RESUMEN

BACKGROUND: To determine which resident and program characteristics correlate with ophthalmic knowledge, as assessed by resident Ophthalmic Knowledge Assessment Program (OKAP) performance. METHODS: An online survey was sent in June 2017 to all US ophthalmology residents who took the OKAP in April 2017. RESULTS: The survey response rate was 13.8% (192/1387 residents). The mean respondent age was 30.4 years, and 57.3% were male. The mean [SD] self-reported 2017 OKAP percentile was 61.9 [26.7]. OKAP performance was found to have a significant positive correlation with greater number of hours spent/week studying for the OKAPs (p = 0.007), with use of online question banks (p < 0.001), with review sessions and/or lectures arranged by residency programs (p < 0.001), and with OKAP-specific didactics (p = 0.002). On multivariable analysis, factors most predictive of residents scoring ≥75th percentile were, higher step 1 scores (OR = 2.48, [95% CI: 1.68-3.64, p < 0.001]), presence of incentives (OR = 2.75, [95% CI: 1.16-6.56, p = 0.022]), greater number of hours/week spent studying (OR = 1.09, [95% CI:1.01-1.17, p = 0.026]) and fewer hours spent in research 3 months prior to examination (OR = 1.08, [95% CI: 1.01-1.15, p = 0.020]. Lastly, residents less likely to depend on group study sessions as a learning method tended to score higher (OR = 3.40, [95% CI: 1.16-9.94, p = 0.026]). CONCLUSIONS: Programs wishing to improve resident OKAP scores might consider offering incentives, providing effective access to learning content e.g. online question banks, and adjusting the curriculum to highlight OKAP material. Step 1 scores may help educators identify residents who might be at risk of not performing as well on the OKAP.

RESUMEN

BACKGROUND: Cataract and age-related macular degeneration (AMD) are common causes of decreased vision that often occur simultaneously in people over age 50. Although cataract surgery is an effective treatment for cataract-induced visual loss, some clinicians suspect that such an intervention may increase the risk of worsening of underlying AMD and thus have deleterious effects on vision. OBJECTIVES: The objective of this review was to evaluate the effectiveness and safety of cataract surgery compared with no surgery in eyes with AMD. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 11), Ovid MEDLINE, Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily (January 1946 to December 2016), Embase (January 1980 to December 2016), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to December 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 2 December 2016. SELECTION CRITERIA: We included randomized controlled trials (RCTs) and quasi-randomized trials that enrolled participants whose eyes were affected by both cataract and AMD in which cataract surgery was compared with no surgery. DATA COLLECTION AND ANALYSIS: Two review authors independently evaluated the search results against the inclusion and exclusion criteria. Two review authors independently extracted data, assessed risk of bias for included studies, and graded the certainty of evidence. We followed methods as recommended by Cochrane. MAIN RESULTS: We included two RCTs with a total of 114 participants (114 study eyes) with visually significant cataract and AMD. We identified no ongoing trials. Participants in each RCT were randomized to immediate cataract surgery (within two weeks of enrollment) or delayed cataract surgery (six months after enrollment). The risk of bias was unclear for most domains in each study; one study was registered prospectively.In one study conducted in Australia outcomes were reported only at six months (before participants in the delayed-surgery group had cataract surgery). At six months, the immediate-surgery group showed mean improvement in best-corrected visual acuity (BCVA) compared with the delayed-surgery group (mean difference (MD) -0.15 LogMAR, 95% confidence interval (CI) -0.28 to -0.02; 56 participants; moderate-certainty evidence). In the other study, conducted in Austria, outcomes were reported only at 12 months (12 months after participants in the immediate-surgery group and six months after participants in the delayed-surgery group had cataract surgery). There was uncertainty as to which treatment group had better improvement in distance visual acuity at 12 months (unit of measure not reported; very low-certainty evidence).At 12 months, the mean change from baseline between groups in cumulated drusen or geographic atrophy area size was small and there was uncertainty which, if either, of the groups was favored (MD 0.76, 95% CI -8.49 to 10.00; 49 participants; low-certainty evidence). No participant in one study had exudative AMD develop in the study eye during 12 months of follow-up; in the other study, choroidal neovascularization developed in the study eye of 1 of 27 participants in the immediate-surgery group versus 0 of 29 participants in the delayed-surgery group at six months (risk ratio 3.21, 95% CI 0.14 to 75.68; 56 participants; very low-certainty evidence). Quality of life was measured using two different questionnaires. Scores on the Impact of Vision Impairment (IVI) questionnaire suggested that the immediate-surgery group fared better regarding vision-related quality of life than the delayed-surgery group at six months (MD in IVI logit scores 1.60, 95% CI 0.61 to 2.59; low-certainty evidence). However, we could not analyze scores from the Visual Function-14 (VF-14) questionnaire from the other study due to insufficient data. No postoperative complication was reported from either study. AUTHORS' CONCLUSIONS: At this time, it is not possible to draw reliable conclusions from the available data as to whether cataract surgery is beneficial or harmful in people with AMD after 12 months. Although cataract surgery provides short-term (six months) improvement in BCVA in eyes with AMD compared with no surgery, it is unclear whether the timing of surgery has an effect on long-term outcomes. Physicians must make recommendations to their AMD patients regarding cataract surgery based on experience and clinical judgment until large controlled trials are conducted and their findings published.There is a need for prospective RCTs in which cataract surgery is compared with no surgery in people with AMD to better evaluate whether cataract surgery is beneficial or harmful in all or a subset of AMD patients. However, ethical considerations preclude withholding surgery, or delaying it for several years, if it may be a potentially beneficial treatment. Designers of future trials are encouraged to utilize existing standardized systems for grading cataract and AMD and for measuring key outcomes: visual acuity, change in visual acuity, worsening of AMD, quality of life measures, and adverse events.

RESUMEN

We report an aggressive fungal keratitis caused by a putatively novel species of Lophotrichus in a patient with traumatic injury to the cornea from a dog paw. The organism was isolated from the patient's necrotic cornea, which perforated despite coverage with hourly fortified broad-spectrum topical antibiotic therapy. This report represents the first case of human infection caused by this species.

RESUMEN

BACKGROUND: Acanthamoeba are microscopic, free-living, single-celled organisms which can infect the eye and lead to Acanthamoeba keratitis (AK). AK can result in loss of vision in the infected eye or loss of eye itself; however, there are no formal guidelines or standards of care for the treatment of AK. OBJECTIVES: To evaluate the relative effectiveness and safety of medical therapy for the treatment of AK. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2015, Issue 1), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to January 2015), EMBASE (January 1980 to January 2015), PubMed (1948 to January 2015), Latin American and Caribbean Health Sciences Literature Database (LILACS) (1982 to January 2015), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic search for trials. We last searched the electronic databases on 9 January 2015. SELECTION CRITERIA: We included randomized controlled trials (RCTs) of medical therapy for AK, regardless of the participants' age, sex, or etiology of disease. We included studies that compared either anti-amoeba therapy (drugs used alone or in combination with other medical therapies) with no anti-amoeba therapy or one anti-amoeba therapy with another anti-amoeba therapy. DATA COLLECTION AND ANALYSIS: Two authors independently screened search results and full-text reports, assessed risk of bias, and abstracted data. We used standard methodological procedures as set forth by the Cochrane Collaboration. MAIN RESULTS: We included one RCT (56 eyes of 55 participants) in this review. The study compared two types of topical biguanides for the treatment of AK: chlorhexidine 0.02% and polyhexamethylene biguanide (PHMB) 0.02%. All participants were contact lens wearers with a median age of 31 years. Treatment duration ranged from 51 to 145 days. The study, conducted in the UK, was well-designed and had low risk of bias overall.Outcome data were available for 51 (91%) of 56 eyes. Follow-up times for outcome measurements in the study were not reported. Resolution of infection, defined as control of ocular inflammation, relief of pain and photosensitivity, and recovery of vision, was 86% in the chlorhexidine group compared with 78% in the PHMB group (relative risk (RR) 1.10, 95% confidence intervals (CI) 0.84 to 1.42). In the chlorhexidine group, 20 of 28 eyes (71%) had better visual acuity compared with 13 of 23 eyes (57%) in the PHMB group at final follow-up (RR 1.26, 95% CI 0.82 to 1.94). Five participants required therapeutic keratoplasty: 2 in the chlorhexidine group compared with 3 in the PHMB group (RR 0.55, 95% CI 0.10 to 3.00). No serious adverse event related to drug toxicity was observed in the study. AUTHORS' CONCLUSIONS: There is insufficient evidence to evaluate the relative effectiveness and safety of medical therapy for the treatment of AK. Results from the one included study yielded no difference with respect to outcomes reported between chlorhexidine and PHMB. However, the sample size was inadequate to detect clinically meaningful differences between the two groups as indicated by the wide confidence intervals of effect estimates.

RESUMEN

Objective: To demonstrate that electronic health record (EHR) data can be used in an automated approach to evaluate cataract surgery outcomes. Design: Retrospective analysis. Subjects: Resident and faculty surgeons. Methods: Electronic health record data were collected from cataract surgeries performed at the Johns Hopkins Wilmer Eye Institute, and cases were categorized into resident or attending as primary surgeon. Preoperative and postoperative visual acuity (VA) and unplanned return to operating room were extracted from the EHR. Main Outcome Measures: Postoperative VA and reoperation rate within 90 days. Results: This study analyzed 14 537 cataract surgery cases over 32 months. Data were extracted from the EHR using an automated approach to assess surgical outcomes for resident and attending surgeons. Of 337 resident surgeries with both preoperative and postoperative VA data, 248 cases (74%) had better postoperative VA, and 170 cases (51%) had more than 2 lines improvement. There was no statistical difference in the proportion of cases with better postoperative VA or more than 2 lines improvement between resident and attending cases. Attending surgeons had a statistically greater proportion of cases with postoperative VA better than 20/40, but this finding has to be considered in the context that, on average, resident cases started out with poorer baseline VA.A multivariable regression model of VA outcomes vs. resident/attending status that controlled for preoperative VA, patient age, American Society of Anesthesiologists (ASA) score, and estimated income found that resident status, preoperative VA, patient age, ASA score, and estimated income were all significant predictors of VA. The rate of unplanned return to the operating room within 90 days of cataract surgery was not statistically different between resident (1.8%) and attending (1.2%) surgeons. Conclusions: This study demonstrates that EHR data can be used to evaluate and monitor surgical outcomes in an ongoing way. Analysis of EHR-extracted cataract outcome data showed that preoperative VA, ASA classification, and attending/resident status were important in predicting postoperative VA outcomes. These findings suggest that the utilization of EHR data could enable continuous assessment of surgical outcomes and inform interventions to improve resident training.

RESUMEN

Background: Currently, surgical education utilizes a combination of the apprentice model, wet-lab training, and simulation, but due to reliance on subjective data, the quality of teaching and assessment can be variable. The "language of surgery," an established concept in engineering literature whose incorporation into surgical education has been limited, is defined as the description of each surgical maneuver using quantifiable metrics. This concept is different from the traditional notion of surgical language, generally thought of as the qualitative definitions and terminology used by surgeons. Methods: A literature search was conducted through April 2023 using MEDLINE/PubMed using search terms to investigate wet-lab, virtual simulators, and robotics in ophthalmology, along with the language of surgery and surgical education. Articles published before 2005 were mostly excluded, although a few were included on a case-by-case basis. Results: Surgical maneuvers can be quantified by leveraging technological advances in virtual simulators, video recordings, and surgical robots to create a language of surgery. By measuring and describing maneuver metrics, the learning surgeon can adjust surgical movements in an appropriately graded fashion that is based on objective and standardized data. The main contribution is outlining a structured education framework that details how surgical education could be improved by incorporating the language of surgery, using ophthalmology surgical education as an example. Conclusion: By describing each surgical maneuver in quantifiable, objective, and standardized terminology, a language of surgery can be created that can be used to learn, teach, and assess surgical technical skill with an approach that minimizes bias. Key message: The "language of surgery," defined as the quantification of each surgical movement's characteristics, is an established concept in the engineering literature. Using ophthalmology surgical education as an example, we describe a structured education framework based on the language of surgery to improve surgical education. Classifications: Surgical education, robotic surgery, ophthalmology, education standardization, computerized assessment, simulations in teaching. Competencies: Practice-Based Learning and Improvement.

RESUMEN

PRCIS: Cataract, glaucoma, and glaucoma suspect patients report differing visual symptoms. Asking patients about their visual symptoms may provide useful diagnostic information and inform decision-making in patients with comorbid conditions. PURPOSE: To compare visual symptoms in glaucoma, glaucoma suspect (controls), and cataract patients. METHODS: Glaucoma, cataract, and glaucoma suspect patients at Wilmer Eye Institute responded to a questionnaire rating the frequency and severity of 28 symptoms. Univariate and multivariable logistic regression determined the symptoms that best differentiate each disease pair. RESULTS: In all, 257 patients (mean age: 67.4 ± 13.4 y; 57.2% female; 41.2% employed), including 79 glaucoma, 84 cataract, and 94 glaucoma suspect patients, participated. Compared with glaucoma suspects, glaucoma patients were more likely to report poor peripheral vision (OR 11.29, 95% CI: 3.73-34.16), better vision in 1 eye (OR 5.48, 95% CI: 1.33-22.64), and light sensitivity (OR 4.85, 95% CI: 1.78-13.24), explaining 40% of the variance in diagnosis (ie, glaucoma vs. glaucoma suspect). Compared with controls, cataract patients were more likely to report light sensitivity (OR 3.33, 95% CI: 1.56-7.10) and worsening vision (OR 12.20, 95% CI: 5.33-27.89), explaining 26% of the variance in diagnosis (ie, cataract vs. glaucoma suspect). Compared with cataract patients, glaucoma patients were more likely to report poor peripheral vision (OR 7.24, 95% CI: 2.53-20.72) and missing patches (OR 4.91, 95% CI: 1.52-15.84), but less likely to report worsening vision (OR 0.08, 95% CI 0.03-0.22), explaining 33% of the variance in diagnosis (ie, glaucoma vs. cataract). CONCLUSIONS: Visual symptoms distinguish disease state to a moderate degree in glaucoma, cataract, and glaucoma suspect patients. Asking about visual symptoms may serve as a useful diagnostic adjunct and inform decision-making, for example, in glaucoma patients considering cataract surgery.

RESUMEN

Purpose: To estimate the opportunity cost to attending surgeons of teaching residents cataract surgery in the operating room. Patients and methods: Operating room records at an academic teaching hospital from July 2016 to July 2020 were analyzed in this retrospective review of cases. Cases were identified using Current Procedural Terminology (CPT) codes 66982 and 66984 for cataract surgery. Outcomes measured include operative time and work relative value units (wRVUs). Cost analysis was performed using the generic 2021 Medicare Conversion Factor. Results: Of 8813 cases, 2906 (33.0%) included resident involvement. For CPT 66982 cases, median (interquartile range (IQR)) operative time was 47 (22) minutes with resident involvement and 28 (18) minutes without (p<0.001). For CPT 66984 cases, median (IQR) operative time was 34 (15) minutes with resident involvement and 20 (11) minutes without (p<0.001). Median wRVUs was 78.5 (20.9) with resident involvement and 61.0 (14.4) without (p<0.001) which converted to an opportunity cost (IQR) per case of $1393.72 ($1055.63). Among cases involving residents, median operative time was significantly higher during the first and second quarters (p<0.001) and for every quarter when compared to cases performed by attendings only (p<0.001). Conclusion: Teaching cataract surgery in the operating room is associated with a considerable opportunity cost for attending surgeons.

RESUMEN

PURPOSE: To evaluate the cost-effectiveness of phacoemulsification simulation training in virtual reality simulator and wet laboratory on operating theater performance. METHODS: Residents were randomized to a combination of virtual reality and wet laboratory phacoemulsification or wet laboratory phacoemulsification. A reference control group consisted of trainees who had wet laboratory training without phacoemulsification. All trainees were assessed on operating theater performance in 3 sequential cataract patients. International Council of Ophthalmology Surgical Competency Assessment Rubric-phacoemulsification (ICO OSCAR phaco) scores by 2 masked independent graders and cost data were used to determine the incremental cost-effectiveness ratio (ICER). A decision model was constructed to indicate the most cost-effective simulation training strategy based on the willingness to pay (WTP) per ICO OSCAR phaco score gained. RESULTS: Twenty-two trainees who performed phacoemulsification in 66 patients were analyzed. Trainees who had additional virtual reality simulation achieved higher mean ICO OSCAR phaco scores compared with trainees who had wet laboratory phacoemulsification and control (49.5 ± standard deviation [SD] 9.8 vs 39.0 ± 15.8 vs 32.5 ± 12.1, P < .001). Compared with the control group, ICER per ICO OSCAR phaco of wet laboratory phacoemulsification was $13,473 for capital cost and $2209 for recurring cost. Compared with wet laboratory phacoemulsification, ICER per ICO OSCAR phaco of additional virtual reality simulator training was US $23,778 for capital cost and $1879 for recurring cost. The threshold WTP values per ICO OSCAR phaco score for combined virtual reality simulator and wet laboratory phacoemulsification to be most cost-effective was $22,500 for capital cost and $1850 for recurring cost. CONCLUSIONS: Combining virtual reality simulator with wet laboratory phacoemulsification training is effective for skills transfer in the operating theater. Despite of the high capital cost of virtual reality simulator, its relatively low recurring cost is more favorable toward cost-effectiveness.

RESUMEN

PURPOSE: To determine whether VISX S4 (VISX Inc) custom photorefractive keratectomy (PRK) results in better visual outcomes than VISX S4 conventional PRK. METHODS: Photorefractive keratectomy was performed on 80 eyes from 40 patients in this randomized, prospective, contralateral eye study. Dominant eyes were randomized to one group with the fellow eye receiving the alternate treatment. Primary outcome measures included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), contrast sensitivity, and root-mean-square (RMS) higher order aberrations. RESULTS: Mean UDVA was -0.023±0.099 (20/19) in the custom group and -0.044±0.080 (20/18) in the conventional group 6 months after surgery (P=.293). Mean CDVA was -0.073±0.067 (20/17) in the custom group and -0.079±0.071 (20/17) in the conventional group 6 months after surgery (P=.659). Total higher order aberration RMS and spherical aberration increased in both groups compared to preoperative values (P<.05). Coma increased in the conventional group (P<.05) whereas it was similar to preoperative values in the custom group. No significant differences were noted in induction of trefoil. CONCLUSIONS: Custom and conventional PRK were shown to be safe and effective with excellent visual acuity and contrast sensitivity performance at 6 and 12 months. Conventional PRK induced more coma than custom PRK; however, this did not seem to correlate with clinical outcomes.

RESUMEN

BACKGROUND: Cataract and age-related macular degeneration (AMD) are common causes of decreased vision that often occur simultaneously in people over age 50. Although cataract surgery is an effective treatment for cataract-induced visual loss, some clinicians suspect that such an intervention may increase the risk of worsening of underlying AMD and thus have deleterious effects on vision. OBJECTIVES: The objective of this review was to evaluate the effectiveness and safety of cataract surgery in eyes with AMD. SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2012, Issue 4), MEDLINE (January 1950 to April 2012), EMBASE (January 1980 to April 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to April 2012), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 16 April 2012. SELECTION CRITERIA: We included randomized controlled trials (RCTs) and quasi-randomized trials of eyes affected by both cataract and AMD in which cataract surgery would be compared to no surgery. DATA COLLECTION AND ANALYSIS: Two authors independently evaluated the search results against the inclusion and exclusion criteria. Two authors independently extracted data and assessed risk of bias for included studies. We resolved discrepancies by discussion. MAIN RESULTS: One RCT with 60 participants with visually significant cataract and AMD was included in this review. Participants were randomized to immediate cataract surgery (within two weeks of enrollment) (n = 29) or delayed cataract surgery (six months after enrollment) (n = 31). At six months, four participants were lost to follow-up; two participants from each group. The immediate surgery group showed mean improvement in best-corrected visual acuity (BCVA) compared with the delayed surgery group at six months (mean difference (MD) 0.15 LogMAR, 95% confidence interval (CI) 0.28 to 0.02). There was no significant difference in the development of choroidal neovascularization between groups (1/27 eyes in the immediate surgery group versus 0/29 eyes in the delayed surgery group). Results from Impact of Vision Impairment (IVI) questionnaires suggested that the immediate surgery group faired better with quality of life outcomes than the delayed surgery group (MD in IVI logit scores 1.60, 95% CI 0.61 to 2.59). No postoperative complication was reported. We identified a second potentially relevant study of immediate versus delayed cataract surgery in 54 people with AMD. Results for the study are not yet available, but may be eligible for future updates of this review. AUTHORS' CONCLUSIONS: At this time, it is not possible to draw reliable conclusions from the available data to determine whether cataract surgery is beneficial or harmful in people with AMD. Physicians will have to make practice decisions based on best clinical judgment until controlled trials are conducted and their findings published.It would be valuable for future research to investigate prospective RCTs comparing cataract surgery to no surgery in patients with AMD to better evaluate whether cataract surgery is beneficial or harmful in this group. However ethical considerations need to be addressed when delaying a potentially beneficial treatment and it may not be feasible to conduct a long-term study where surgery is withheld from the control group. Utilization of pre-existing, standardized systems for grading cataract and AMD and measuring outcomes (visual acuity, change in visual acuity, worsening of AMD and quality of life measures) should be encouraged.

RESUMEN

Background: It is essential to log resident-performed procedures to assess training programs and fulfill specialty requirements, but resident case numbers are often underreported. Current systems require inefficient data entry steps, and residents and fellows report that user interfaces and administrative burden contribute to logging inaccuracy. Objective: To determine the accuracy, feasibility, and acceptability of a single logging approach for resident case logging. Methods: In 2018, we implemented a case logging system integrated with the institutional electronic health record (EHR) and the Accreditation Council for Graduate Medical Education (ACGME) case log system to record procedures performed by ophthalmology residents. We compared the proportion of resident-performed cataract extractions in the EHR that were reported to ACGME for 3 periods: before the deployment of the new system (6 months), during the transition (6 months), and after the change (2 years). Resident satisfaction with the new system was evaluated using surveys. Results: An analysis of resident cataract surgeries showed that the percentage of resident cases logged increased from 85% prior to implementation to 91% after implementation. The integrated system became the preferred case logging method, with 100% of all logged cases being entered using the new platform. Surveys showed that the percentage of trainees who were moderately or very satisfied with the case log process increased from 55% before implementation to 100% after implementation. Conclusions: A resident case log system integrated with an EHR more accurately reflects resident operative volume and increases trainee satisfaction with the logging process.

RESUMEN

PURPOSE: Surgeons' skill in the operating room is a major determinant of patient outcomes. Assessment of surgeons' skill is necessary to improve patient outcomes and quality of care through surgical training and coaching. Methods for video-based assessment of surgical skill can provide objective and efficient tools for surgeons. Our work introduces a new method based on attention mechanisms and provides a comprehensive comparative analysis of state-of-the-art methods for video-based assessment of surgical skill in the operating room. METHODS: Using a dataset of 99 videos of capsulorhexis, a critical step in cataract surgery, we evaluated image feature-based methods and two deep learning methods to assess skill using RGB videos. In the first method, we predict instrument tips as keypoints and predict surgical skill using temporal convolutional neural networks. In the second method, we propose a frame-wise encoder (2D convolutional neural network) followed by a temporal model (recurrent neural network), both of which are augmented by visual attention mechanisms. We computed the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and predictive values through fivefold cross-validation. RESULTS: To classify a binary skill label (expert vs. novice), the range of AUC estimates was 0.49 (95% confidence interval; CI = 0.37 to 0.60) to 0.76 (95% CI = 0.66 to 0.85) for image feature-based methods. The sensitivity and specificity were consistently high for none of the methods. For the deep learning methods, the AUC was 0.79 (95% CI = 0.70 to 0.88) using keypoints alone, 0.78 (95% CI = 0.69 to 0.88) and 0.75 (95% CI = 0.65 to 0.85) with and without attention mechanisms, respectively. CONCLUSION: Deep learning methods are necessary for video-based assessment of surgical skill in the operating room. Attention mechanisms improved discrimination ability of the network. Our findings should be evaluated for external validity in other datasets.

RESUMEN

PURPOSE: To evaluate the clinical outcomes of Artisan phakic intraocular lens (PIOL; Ophtec BV) implantation in patients with stable keratoconus. METHODS: In a prospective, nonrandomized case series, 14 Artisan PIOLs and 2 toric Artisan PIOLs were implanted in 13 patients (16 eyes) with stable keratoconus who had contact lens intolerance. Pre- and postoperative data were collected. RESULTS: Mean follow-up was 14.2 ± 7.8 months. Preoperative uncorrected distance visual acuity (UDVA) was counting fingers in all patients. Mean final logMAR (Snellen equivalent) UDVA and corrected distance visual acuity (CDVA) were 0.15(20/28) ± 0.13 and 0.11(20/26) ± 0.10, respectively. The improvements in UDVA and CDVA were statistically significant (P<.0001 and P<.002, respectively). All patients achieved a final UDVA of 20/40 or better, and 84.6% had a final CDVA of 20/32 or better. No postoperative complications occurred except for two cases of sterile uveitis. CONCLUSIONS: Implantation of the Artisan PIOL is effective in improving visual acuity in patients with stable keratoconus. Long-term safety remains to be established as no postoperative endothelial cell counts were performed.

RESUMEN

Surgery is a major source of errors in patient care. Preventing complications from surgical errors in the operating room is estimated to lead to reduction of up to 41 846 readmissions and save $620.3 million per year. It is now established that poor technical skill is associated with an increased risk of severe adverse events postoperatively and traditional models to train surgeons are being challenged by rapid advances in technology, an intensified patient-safety culture, and a need for value-driven health systems. This review discusses the current methods available for evaluating technical skills in cataract surgery and the recent technological advancements that have enabled capture and analysis of large amounts of complex surgical data for more automated objective skills assessment.

RESUMEN

AIM: To identify instrument holding archetypes used by experienced surgeons in order to develop a universal language and set of validated techniques that can be utilized in manual small incision cataract surgery (MSICS) curricula. METHODS: Experienced cataract surgeons performed five MSICS steps (scleral incision, scleral tunnel, side port, corneal tunnel, and capsulorhexis) in a wet lab to record surgeon hand positions. Images and videos were taken during each step to identify validated hand position archetypes. RESULTS: For each MSICS step, one or two major archetypes and key modifying variables were observed, including tripod for scleral incision, tripod-thumb bottom for scleral tunnel, underhand-index to thumb grip for side port, index-contact tripod for corneal entry, and tripod-forceps for capsulorhexis. Key differences were noted in thumb placement and number of fingers supporting the instrument, and modifying variables included index finger curvature and amount of flexion. CONCLUSION: Identification of optimal hand positions and development of a formal nomenclature has the potential to help trainees adopt hand positions in an informed manner, influence instrument design, and improve surgical outcomes.

RESUMEN

IMPORTANCE: Ophthalmology patients are seeking medical advice on social media websites like Reddit, where users are able to post comments and discuss issues pertaining to different topics that are organized in 'subreddits'. Understanding which issues are most pertinent will guide ophthalmic providers in delivering more effective patient education. METHODS: This cross-sectional study assessed a systematic sample of the first 22 posts and their top 3 comments from each month since January 27th, 2019, the subreddit's creation. Information was gathered from reddit.com/r/eyetriage in October 2019 and analyzed in November 2019. MAIN OUTCOMES: The posts were characterized by date and time, inclusion of an image, type, content, emotional tone, and number of upvotes and comments. The comments were categorized based on content, emotional tone, time of comment, and user background. Post and comment content codes were categorized in an iterative manner with differences resolved by author consensus. Categorical statistics were compiled. RESULTS: Two hundred posts and 456 comments were analyzed since the creation of r/eyetriage, a forum created exclusively for patients to seek advice from health-care professionals. Twenty-six (13%) of the total posts included an image. On average, comments received 1.76 ± 2.17 upvotes along with 4.50 ± 4.47 replies. The most common content codes among the posts were 42 (21.0%) seeking diagnoses, 23 (11.5%) surgical complications, and 13 (6.50%) alternative medication options. Eighty-two (41%) posts conveyed a clear emotional tone, most notably 11 (13.4%) with anxiety and 10 (12.2%) with worry. The top comments came from 165 (36.2%) self-identified patients, 151 (33.1%) optometrists, and 49 (10.8%) ophthalmologists. The top comment codes for replies included 158 (34.7%) with treatment advice, 70 (15.4%) with advice deferred to follow-up appointment with other health-care specialists, and 60 (13.2%) with sharing information. CONCLUSIONS: Patients are asking ophthalmology-related questions on the Eye Triage subreddit, and they are more likely to receive information from other patients or optometrists than from self-identified ophthalmologists. When emotions were revealed, patients were often anxious and worried. Opportunities exist for ophthalmologists to take a more active role on this subreddit and help educate patients.

RESUMEN

PURPOSE: To evaluate time as an objective measure of technical skill assessment in cataract surgery. SETTING: Single academic center. DESIGN: Cross-sectional study. METHODS: One hundred videos of cataract surgery (29 performed by a faculty and 71 performed by trainee surgeons) performed at the Wilmer Eye Institute between July 2011 and December 2017 were analyzed for surgical technical skill as a function of time using task-specific indices, global skill indices, and appointment status. RESULTS: Expert surgeons, defined by global skill, did not consistently have shorter times to complete phases in cataract surgery compared with novice surgeons. Time to complete phases in cataract surgery was predictive of global skill (area under the curve [AUC] of 0.73, 95% CI: 0.63-0.83) and of surgeons' appointment status (AUC 0.82, 95% CI: 0.70-0.91). Time for capsulorhexis correctly distinguished between expert-novice skill class only 58% (AUC 0.58, 95% CI: 0.47-0.69) of the times when capsulorhexis indices were used and 51% (AUC 0.51, 95% CI: 0.39-0.63) of the times when global indices were used. Time to complete quadrants in capsulorhexis also had a low ability to discriminate between novice and expert instances for capsulorhexis skill and global skill. The AUC was 0.54 (95% CI: 0.44-0.66) and 0.53 (95% CI: 0.41-0.65) for capsulorhexis skill and global skill, respectively. CONCLUSIONS: Time as an objective measure of skill was limited in its ability to distinguish between expert and novice skill class in a meaningful way.

RESUMEN

PURPOSE: To describe two cases of ectopia lentis with different preoperative management strategies following the initial diagnostic dilated exam. OBSERVATIONS: In both cases, the patients presented with bilateral subluxation of the crystalline lens. Neither patient had a known history of Marfan's disease, homocystinuria or other systemic disorders that affect the body's connective tissue possibly leading to lens subluxation. Patient 1 was sent home after dilated fundus examination with no special precautions. That same night, he developed severe right eye pain and further decreased vision. He was found to have complete dislocation of his right crystalline lens into the anterior chamber with corneal edema and an elevated pressure, requiring an urgent pars plana lensectomy. In our second case of ectopia lentis, patient 2 was examined prior to dilation and noted to have bilateral subluxation of the lens into the vitreous. Twenty minutes after dilation, the crystalline lens was noted to be in the anterior chamber in the right eye. The patient was laid supine for several minutes and once the lens was in the posterior cavity, she was given 1% pilocarpine in both eyes to constrict the pupil to prevent dislocation in the anterior chamber. Patient 2 had an uneventful perioperative period and did not suffer worsening subluxation after her initial visit. CONCLUSION AND IMPORTANCE: Unlike patient 1, patient 2 did not suffer further subluxation after her initial dilated eye exam, therefore avoiding a more arduous clinical and surgical course. Patients presenting with completely dislocated lenses may benefit from the reversal of pupillary dilation by being placed in the supine position and given reversal drops such as 1% pilocarpine prior to leaving the office. This method may help prevent complications from anterior lens subluxation and pupillary block glaucoma until definitive surgical managment.
