RESUMO
INTRODUCTION AND OBJECTIVES: Cataract surgery is one of the most common procedures in outpatient surgery units. The use of information and communication technologies (ICT) in clinical practice and the advent of new health scenarios, such as the Covid pandemic, have driven the development of pre-anaesthesia assessment models that free up resources to improve access to cataract surgery without sacrificing patient safety. The approach to cataract surgery varies considerably among public, subsidised and private hospitals. This raises the need for guidelines to standardise patient assessment, pre-operative tests, management of background medication, patient information and informed consent. RESULTS: In this document, the SEDAR Clinical Management Division together with the Major Outpatient Surgery Division SEDAR Working Group put forward a series of consensus recommendations on pre-anaesthesia testing based on the use of ITCs, health questionnaires, patient information and informed consent supervised and evaluated by an anaesthesiologist. CONCLUSIONS: This consensus document will effectivise pre-anaesthesia assessment in cataract surgery while maintaining the highest standards of quality, safety and legality.

This study assessed the performance of automated machine learning (AutoML) in classifying cataract surgery phases from surgical videos. Two ophthalmology trainees without coding experience designed a deep learning model in Google Cloud AutoML Video Classification for the classification of 10 different cataract surgery phases. We used two open-access publicly available datasets (total of 122 surgeries) for model training, validation and testing. External validation was performed on 10 surgeries issued from another dataset. The AutoML model demonstrated excellent discriminating performance, even outperforming bespoke deep learning models handcrafter by experts. The area under the precision-recall curve was 0.855. At the 0.5 confidence threshold cut-off, the overall performance metrics were as follows: sensitivity (81.0%), recall (77.1%), accuracy (96.0%) and F1 score (0.79). The per-segment metrics varied across the surgical phases: precision 66.7-100%, recall 46.2-100% and specificity 94.1-100%. Hydrodissection and phacoemulsification were the most accurately predicted phases (100 and 92.31% correct predictions, respectively). During external validation, the average precision was 54.2% (0.00-90.0%), the recall was 61.1% (0.00-100%) and specificity was 96.2% (91.0-99.0%). In conclusion, a code-free AutoML model can accurately classify cataract surgery phases from videos with an accuracy comparable or better than models developed by experts.

PURPOSE: To determine the effects of cataract surgery and preoperative factors on the vision-related quality of life (QOL) in patients with retinitis pigmentosa (RP). MATERIALS AND METHODS: This was a prospective, interventional study of 54 patients diagnosed with RP. The 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) was used to determine the QOL before and after the cataract surgery. The correlations between the scores of the questionnaire and the best-corrected visual acuity (BCVA), macular structure, and degree of improvement of the NEI VFQ-25 scores were also determined. RESULTS: Statistically significant improvements were observed in the BCVA and all of the NEI VFQ-25 subscale scores except for color vision. The improvement of general vision was the largest. The postoperative BCVA of the better-seeing eye was more strongly and significantly correlated with the postoperative NEI VFQ-25 scores than that of the worse-seeing eye. All of the postoperative NEI VFQ-25 scores were significantly correlated with the length of the ellipsoid zone (EZ) of the photoreceptors. No significant correlation was found between the preoperative general vision, near vision, mental health scores, and EZ length. All of the preoperative NEI VFQ-25 scores except the social function and mental health scores were negatively and significantly correlated with the degree of improvement of the NEI VFQ-25 score. The EZ length was significantly correlated with the degree of improvement of the NEI VFQ-25 scores of the general vision, distance vision, mental health, dependency, and composite 9 scores. CONCLUSIONS: Cataract surgery can significantly improve the NEI VFQ-25 scores in RP patients. The EZ length can be used to predict the postoperative VFQ scores. We conclude that the NEI VFQ-25 is a useful method to evaluate the impact of cataract surgery on the BCVA in patients with RP.

The eye care sector is well positioned to contribute to the advancement of universal health coverage within countries. Given the large unmet need for care associated with cataract and refractive error, coupled with the fact that highly cost-effective interventions exist, we propose that effective cataract surgery coverage (eCSC) and effective refractive error coverage (eREC) serve as ideal indicators to track progress in the uptake and quality of eye care services at the global level, and to monitor progress towards universal health coverage in general. Global targets for 2030 for these two indicators were endorsed by WHO Member States at the 74th World Health Assembly in May, 2021. To develop consensus on the data requirements and methods of calculating eCSC and eREC, WHO convened a series of expert consultations to make recommendations for standardising the definitions and measurement approaches for eCSC and eREC and to identify areas in which future work is required.

This study evaluated the accuracy of total keratometry (TK) and standard keratometry (K) for intraocular lens (IOL) power calculation in eyes treated with femtosecond laser-assisted cataract surgery. The retrospective study included a retrospective analysis of data from 62 patients (91 eyes) who underwent uneventful femtosecond laser-assisted cataract surgery with Artis PL E (Cristalens Industrie, Lannion, France) IOL implantation by a single surgeon between May 2020 and December 2020 in Severance Hospital, Seoul, South Korea. The new IOLMaster 700 biometry device (Carl Zeiss Meditec, Jena, Germany) was used to calculate TK and K. The mean absolute error (MAE), median absolute error (MedAE), and the percentages of eyes within prediction errors of ± 0.25 D, ± 0.50 D, and ± 1.00 D were calculated for all IOL formulas (SRK/T, Hoffer-Q, Haigis, Holladay 1, Holladay 2, and Barrett Universal II). There was strong agreement between K and TK (intraclass correlation coefficient = 0.99), with a mean difference of 0.04 D. For all formulas, MAE tended to be lower for TK than for K, and relatively lower MAE and MedAE values were observed for SRK/T and Holladay 1. Furthermore, for all formulas, a greater proportion of eyes fell within ± 0.25 D of the predicted postoperative spherical equivalent range in the TK group than in the K group. However, differences in MAEs, MedAEs, and percentages of eyes within the above prediction errors were not statistically significant. In conclusion, TK and K exhibit comparable performance for refractive prediction in eyes undergoing femtosecond laser-assisted cataract surgery.

BACKGROUND: The aim of our case control study was to evaluate the impact of glistening and tear film quality on visual performance after implantation of two different hydrophobic acrylic intraocular lenses (IOLs). MATERIALS AND METHODS: In our retrospective study we included cataract patients operated between January 1, 2011 and December 31, 2012, with follow-up controls between January 2016 and December 2019. Z-Flex 860FAB (Medicontur) and AcrySof IQ SN60WF (Alcon) monofocal IOLs were implanted during standard phacoemulsification. Best corrected distance visual acuity (BCDVA) and contrast sensitivity were monitored over the post-operative period of up to 6 years. Glistening was evaluated semi-quantitatively with slit-lamp biomicroscopy and quantitatively using Pentacam HR (Oculus). Using HD Analyzer OQAS (Visiometrics), total intraocular light diffusion was interpreted with the objective scatter index (OSI) and tear film quality was evaluated with the tear film related objective scatter index (TF-OSI). RESULTS: 26 eyes implanted with the Z-Flex and 25 eyes with the AcrySof IQ IOLs were included in the analysis. The slit-lamp evaluation of patients with the Z-Flex IOL (0.57 ± 0.60) revealed significantly less glistening (p<0.0001), compared to the AcrySof IQ group (1.82 ± 0.90), and these observations were confirmed by the Pentacam HR analyses, as well (Z-Flex group: 35.1 ± 1.63, Acrysof IQ: 39.6 ± 3.69, p<0.0001). TF-OSI differed between the two sets of patients remarkably (1.53 ± 1.03 vs. 2.51 ± 1.76 for AcrySof IQ and Z-Flex groups, respectively, p = 0.043). Both groups of patients provided similar results of BCDVA and contrast sensitivity. CONCLUSION: Glistening and tear film quality both contribute to visual performance outcomes after cataract surgery. In our study the advantage of less glistening in the Z-Flex IOL might have been masked by the adverse effects of the more pronounced tear film insufficiency of these patients, compared to the AcrySof IQ group. Among other factors, tear film quality should also be taken into consideration when comparing the impact of glistening on visual quality of patients implanted with different IOLs.

Cataract is the second leading cause of preventable blindness on the globe. Several programs across the country have been running efficiently to increase the cataract surgical rates and decrease blindness due to cataract. The current COVID-19 pandemic has led to a complete halt of these programs and thus accumulating all the elective cataract procedures. At present with the better understanding of the safety precautions among the health care workers and general population the Government of India (GoI) has given clearance for functioning of eye care facilities. In order to facilitate smooth functioning of every clinic, in this paper, we prepared preferred practice pattern based on consensus discussions between leading ophthalmologists in India including representatives from major governmental and private institutions as well as the All India Ophthalmological Society leadership. These guidelines will be applicable to all practice settings including tertiary institutions, corporate and group practices and individual eye clinics. The guidelines include triage, use of personal protective equipment, precautions to be taken in the OPD and operating room as well for elective cataract screening and surgery. These guidelines have been prepared based on current situation but are expected to evolve over a period of time based on the ongoing pandemic and guidelines from GoI.

PURPOSE: To facilitate the development of standardized guidelines for the surgical management of patients with pediatric traumatic cataracts by assessing current ophthalmologists' practice patterns. METHODS: This was a cross-sectional, observational, and retrospective study. A 24-question electronic survey of current practices pertaining to the surgical management of pediatric traumatic cataracts was sent to pediatric ophthalmologists worldwide. Preferences for pre-operative evaluation, surgical timing and techniques, and postoperative management were analyzed. RESULTS: Of the 56 respondents, 62.5% practiced in academic settings. Of the 49 respondents (87.5%) who performed pediatric ruptured globe repair, 41.7% would perform simultaneous cataract extraction if anterior capsular violation existed, whereas 4.1% would do so without capsular violation (P < .001). Most respondents (50.9%) would remove visually significant cataracts within 4 weeks in patients within the amblyogenic age range (P = .02), whereas 63.6% would wait longer outside the amblyogenic range. Preferences for intraocular lens selection, primary posterior capsulotomy, and timing of amblyopia therapy differed. CONCLUSIONS: Individual management practices regarding pediatric traumatic cataracts vary depending on associated globe injuries and patient age. Trends exist in surgical planning, intraoperative techniques, and visual rehabilitation methods, but no single approach has achieved complete unanimity. Therefore, further investigation into optimal timing and the extent of surgical intervention, refractive correction, and postoperative care is necessary prior to developing evidence-based guidelines for enhancing visual outcomes in this population.

Construct: Authors investigated the perspectives of stakeholders on feasibility elements of workplace-based assessments (WBA) with varying designs. Background: In the transition to competency-based medical education, WBA are taking a more prominent role in assessment programs. However, the increased demand for WBA leads to new challenges for implementing suitable WBA tools with published validity evidence, while also being feasible and useful in practice. Despite the availability of published WBA tools, implementation does not necessarily occur; a more fulsome understanding of the perspectives of stakeholders who are ultimately the end-users of these tools, as well as the system factors that both deter or support their use, could help to explain why evidence-based assessment tools may not be incorporated into residency programs. Approach: We examined the perspectives of two groups of stakeholders, surgical teachers and resident learners, during an assessment intervention that varied the assessment tools while keeping the assessment process constant. We chose diverse exemplars from published assessment tools that each represented a different response format: global rating scales, step-by-step surgical rubrics, and an entrustability scale. The primary purpose was to investigate how stakeholders are impacted by WBA tools with varying response formats to better understand their feasibility for assessment of cataract surgery. Secondarily, we were able to explore the culture of assessment in cataract surgery education including stakeholders' perceptions of WBA unrelated to assessment form design. Semi-structured interviews with teachers and a focus group with the residents enabled discussion of their perspectives on dimensions of the tools such as acceptability, demand, implementation, practicality, adaptation, and integration. Findings: Three themes summarize teachers' and residents' experiences with the assessment tools: (1) Feedback is the priority; (2) Forms informing coaching; and (3) Forcing the conversation. The tools helped to facilitate the feedback conversation by serving as a reminder to initiate the conversation, a framework to structure the conversation, and a memory aid for providing detailed feedback. Surgical teachers preferred the assessment tool with a design that best aligned with their approach to teaching and how they wanted to provide feedback. Orientation to the tools, combined with established remediation pathways, may help preceptors to better use assessment tools and improve their ability to give critical feedback. Conclusions: Feedback, more so than assessment, dominated the comments provided by both teachers and residents after using the various WBA tools. Our typical assessment design efforts focus on the creation or selection of a robust assessment tool according to good design and measurement principles, but the current findings would encourage us to also prioritize the coaching relationship and include efforts to design WBA tools to function as a mediator to augment teaching, learning, and feedback exchange within that relationship in the workplace.

INTRODUCTION: Cataract surgery is the most commonly performed surgery in the world, and its success depends in part on the quality of mydriasis. PURPOSE: To compare, for the same eye, the pupillary dilation obtained with Mydrane® (standardized intracameral solution of 0.02% tropicamide, combined with 0.31% phenylephrine and 1% lidocaine) intraoperatively versus Mydriasert® (0.28mg tropicamide insert and 5.4mg phenylephrine) with a contact time between 45 and 60 minutes in the preoperative period. METHODS: Single center prospective study from November 2016 to January 2018 at the Laveran Army Instructional Hospital in Marseille. Patients referred for surgery were dilated at the preoperative consultation with Mydriasert®. The pupillary diameter after 45-60 minutes of contact with the insert was manually measured, by two different examiners, through the "iris image" tab of the Pentacam® elevation topography. Patients were dilated on the day of their cataract surgery with 0.2cc of Mydrane® injected in the anterior chamber through a paracentesis. Thirty seconds later, prior to injection of viscoelastic, an eye photograph was taken by screen capture. The pupillary diameter was evaluated by two different examiners with to the Piximeter 5.9 metrology software. The difference in pupil dilation between Mydriasert® and Mydrane® was tested with the paired series Student t-test. RESULTS: A hundred and eleven eyes of 82 patients were included. Mydriasert® achieved a mean pupillary dilation of 7.21±0.79mm. The mydriasis obtained with Mydrane® averaged 6.35±0.8mm. This difference of 0.86mm was statistically significant (P<0.001) with a confidence interval of 95% [-0.97; -0.74]. CONCLUSION: On average, Mydrane® dilates the pupil less than Mydriasert®. However, the mydriasis obtained with Mydrane® remains comfortable for the performance of the capsulorhexis. It helps save preoperative time and affords additional anesthetic to the cataract surgery. Nevertheless, the use of Mydriasert® is beneficial when extra mydriasis is required.

BACKGROUND: A proactive risk assessment using the Healthcare Failure Mode and Effect Analysis (HFMEA) process was completed on the intraocular lens (IOL) selection and implantation process to analyze system vulnerabilities that could cause patient harm. The three largest ophthalmology clinics based on patient surgical volume were studied in the analysis. The analysis included in-clinic eye measurements needed for IOL selection through the actual implantation of the lens in the operating room. METHODS: The HFMEA process was used for the analysis. A detailed process and subprocess diagram was created through interviews and observations. A multidisciplinary team met 12 times over a 14-week period, evaluating 170 discrete process and subprocess steps and identifying 177 failure modes and 75 failure mode causes for analysis. RESULTS: A high degree of process variability and lack of a robust quality assurance process was found. Areas for improvement included reducing variability between and within clinics, reducing variability in processes used by surgeons, modifying equipment and software to better support the work processes, and implementing a quality assurance program requiring observation of staff performing their routine work as opposed to relying on self-reports of quality metrics. CONCLUSION: The HFMEA process provided a more complete understanding of all of the processes associated with cataract surgery. This allowed for the identification of a variety of risk factors to patient safety that had not previously been identified by the more traditional reactive analysis methods, which tend to focus only on vulnerabilities identified by a specific event.

INTRODUCTION: This retrospective consecutive case series assessed 12-month effectiveness and safety of iStent® or iStent inject® trabecular micro-bypass implants with cataract surgery in patients with open-angle glaucoma (OAG) in a real-world clinical setting. METHODS: Effectiveness outcomes consisted of intraocular pressure (IOP) reduction; glaucoma medication reduction; proportions of eyes achieving IOP < 18, < 15, or < 12 mmHg; and proportional analysis of medication usage. Safety outcomes included adverse events, secondary surgeries, and best-corrected visual acuity (BCVA). RESULTS: This evaluation included 58 eyes with OAG (35 iStent, 23 iStent inject), with 96.6% of eyes having mild or moderate glaucoma. Diagnoses included primary open-angle glaucoma (the majority; 72.4%), pseudoexfoliative glaucoma, and pigmentary glaucoma. Baseline mean IOP and medications were statistically comparable between groups: 16.1 ± 3.6 mmHg on a mean of 1.8 ± 0.8 medications in the iStent group, and 16.2 ± 3.1 mmHg on a mean of 1.7 ± 0.8 medications in the iStent inject group. Twelve months after stent-cataract surgery, mean IOP was significantly lower in the iStent inject group than in the iStent group (13.1 mmHg vs. 15.4 mmHg, respectively; p < 0.001), and the percent reduction in IOP from baseline was significantly greater in iStent inject eyes than in iStent eyes (19.1% vs. 4.3% reduction, respectively; p < 0.001). At 12 months postoperative, significantly greater proportions of iStent inject eyes than iStent eyes achieved IOP < 18 mmHg (100% vs. 80.0% of eyes, respectively; p = 0.035), IOP < 15 mmHg (73.9% vs. 34.3% of eyes, respectively; p = 0.003), and IOP < 12 mmHg (26.1% vs. 0% of eyes, respectively; p = 0.002). Meanwhile, both groups achieved significant medication reductions at 12 months vs. baseline (94.1% reduction in iStent inject eyes, p < 0.0001; and 72.2% reduction in iStent eyes, p < 0.0001), with the percent reduction being significantly greater in iStent inject eyes than in iStent eyes (p = 0.023). At 12 months, mean number of medications was significantly lower in iStent inject eyes than iStent eyes (0.1 vs. 0.5 medications, respectively; p = 0.021), and significantly more iStent inject eyes (95.7%) than iStent eyes (71.4%) were off medications entirely (p = 0.021). A similarly high safety profile was observed in both groups. CONCLUSION: iStent or iStent inject implantation with cataract surgery resulted in substantial and safe reductions in IOP and medications through 12 months postoperative. Consistent with prior observations, greater efficacy was observed with iStent inject than with iStent. FUNDING: The Rapid Service Fees were funded by Glaukos Corporation.

Cataract surgery is the most common operation performed in most developed countries, including Canada. Nuanced, evidence-driven policies are needed to ensure appropriate access to this sight-saving operation while maintaining the highest standards in quality of care. The Vision Health Services Research Program at Queen's University, in partnership with members of the Ontario Provincial Vision Task Force, has developed evidence to inform policies aimed at optimizing both access and quality across the eye care spectrum.

OBJECTIVE: To evaluate preoperative testing for cataract surgery, implement stakeholder-driven change, and increase the number of patients who arrived for surgery with complete preoperative requirements, for the purpose of delivering safe, high-quality, and cost-effective care for patients. DESIGN: Quality improvement. PARTICIPANTS: Cataract surgery patients, health care staff in Ophthalmology Day Surgery, an Ophthalmology improvement team, the Clinical Section Heads of Ophthalmology and Anaesthesia, Quality Consultants, and members of the Quality Council participated in this study. METHODS: A lean quality improvement approach was used to define and build understanding of the problem. Between July and November 2016, a chart-based reporting system captured all patients who arrived for cataract surgery with expired or incomplete preoperative requirements. A cost analysis was completed, and evidence was reviewed to ensure alignment with best practice preoperative recommendations. RESULTS: On average, 25% (619/2451 over a 17-week period) of patients per day arrived at the Ophthalmology Day Surgery for cataract surgery with incomplete and/or expired physical history forms and ECGs. An improvement team worked to implement a radical improvement idea and relied on an existing questionnaire to ensure patient safety preoperatively. CONCLUSIONS: Based on the literature, best practice guidelines, and a cost analysis, it was decided that patients undergoing routine cataract surgery in Edmonton Zone Hospitals under regional anaesthesia would no longer require physician history and physicals and ECGs. Elimination of the preoperative requirements for all but select high-risk patients meant that 100% of patients who arrived for cataract surgery would not have outstanding presurgery requirements.

INTRODUCTION: In 2017, over 75,000 cataract surgeries were performed within the Veterans Health Administration System (VHA). Previous reports of outcomes of cataract surgery in veterans include patients with pre-existing ocular disease, which can affect vision. To exclude the confounding factor of pre-existing ocular comorbidities, we investigated the long-term visual outcomes and complications associated with small incision cataract surgery performed on veterans without any pre-existing eye disease. MATERIALS AND METHODS: Institutional Review Board approved cohort study with detailed retrospective chart review of all phacoemulsification (small incision) cataract surgeries performed at the Veterans Affairs Medical Center in Washington D.C. over 11 years, including all pre-and postoperative visits until postoperative month 12. RESULTS: A total of 1,513 consecutive surgical cases without any pre-existing ocular disease except the cataract were included. Vision improved significantly after cataract surgery compared to the preoperative best-corrected visual acuity (BCVA) (p = 0.0001) and remained stable over the first intra- and postoperative year. All eyes without complicated surgery and 99.1% of eyes with complications achieved 20/40 or better final vision postoperatively. The most common intra-and postoperative complications were vitreous loss (3.1%) and cystoid macular edema (CME; 1.4%). Patients with complications achieved final mean BCVA of 0.04 (20/22, vitreous loss) and 0.06 (20/23, CME) mean logMAR (Snellen). CONCLUSION: Analysis of 11 years of small incision cataract surgery in eyes without pre-existing ocular disease within the VHA showed significant improvement in vision and stability 12 months after uncomplicated and complicated surgery in veterans.

In January 2015 Zilveren Kruis, the largest health insurer in The Netherlands, engaged in a new three-year, unlimited volume contract with five carefully selected providers of cataract surgery. Zilveren Kruis used a novel method, designed to identify the top expert providers in a certain discipline. This procedure for provider selection uses the principles of Best Value Procurement (BVP), and puts the provider in charge of defining key performance indicators for health care quality. The procedure empowers the professional and acknowledges that the provider, not the purchaser, is the true expert in defining what is high quality care. This new approach focuses purely on provider selection and is thus complementary to innovations in health care reimbursement, such as value-based hospital purchasing or outcome-based financing. We describe this novel approach to preferred provider selection and show how it makes affordable quality the core topic in negotiations with providers.
