RESUMO

PURPOSE: To assess the accuracy of intraocular lens (IOL) power calculation in different age groups using various IOL calculation formulas. METHODS: Data from 421 eyes of 421 patients ≥60 years old (ages: 60-69, n = 131; 70-74, n = 105; 75-84, n = 158 and ≥85, n = 27), who underwent uneventful cataract surgery with SN60WF IOL implantation at John A. Moran Eye Center, Salt Lake City, USA, were retrospectively obtained. The SD of the prediction error (PE), median and mean absolute PEs and the percentage of eyes within ±0.25, ±0.50, ±0.75 and ±1.00 D were calculated after constant optimizations for the following formulas: Barrett Universal II (BUII), Emmetropia Verifying Optical (EVO) 2.0, Haigis, Hoffer Q, Hoffer QST, Holladay 1, Kane, Radial Basis Function (RBF) 3.0 and SRK/T. Results were compared between the different age groups. RESULTS: Predictability rates within 0.25D were lower for the eldest age group compared with the other groups using the EVO 2.0 (33% vs. 37%-53%, p = 0.045), Kane (26% vs. 35%-50%, p = 0.034) and SRK/T (22% vs. 31%-49%, p = 0.002). Higher median absolute refractive errors for all formulas were observed in the oldest group [range: 0.39 D (Haigis, Hoffer QSR)-0.48 D (Kane)], followed by the youngest group [range: 0.30 D (RBF 3.0)-0.39 D (Holladay 1, SRK/T)] but did not reach statistical significance. No significant differences between the groups in the distribution parameter were seen. CONCLUSION: Current IOL power calculation formulas may have variable accuracy for different age groups. This should be taken into account when planning cataract surgery to improve refractive outcomes.

RESUMO

Purpose: To evaluate efficiency of grooving, nuclear fragment removal, and changes in pressure control in the Oertli Faros using traditional peristaltic and Speed and Precision (SPEEP) features. The SPEEP mode uses novel peristaltic technology permitting independent control of flow and vacuum. Methods: A porcine lens model was used with an enclosed chamber simulating the anterior segment. Grooving efficiency is evaluated with flow rates of 10, 30, and 50 mL/min using whole lenses. Lens cubes were emulsified at 20, 40, 60, 80, and 100% power with both SPEEP and non-SPEEP modes. Surge was evaluated with pressure gauges placed on the irrigation tubing and aspiration tubing. Pressure readings were recorded per the following: fluid and vacuum were initiated for 15 seconds, vacuum tubing was occluded for 5 seconds, tubing patency was then re-introduced for 15 seconds. Differences between sensors were recorded. Results: No significant increase in efficiency was seen with increasing flow rate from 30 to 50 mL/min using SPEEP. No significant differences were shown in lens fragment removal in SPEEP and non-SPEEP modes at any power tested. Pressure difference measurements were not significantly different with SPEEP and non-SPEEP modes. Conclusion: We showed that lower flow rates show comparable efficiency of grooving when using the SPEEP mode. The SPEEP function did not show increased efficiency in nuclear fragment removal when compared to traditional mode. Surge control was also comparable with both SPEEP and non-SPEEP modes. We suggest that the SPEEP function included in the Oertli Faros may have some advantages.

RESUMO

PURPOSE: To determine whether there is a difference in efficiency during phacoemulsification when using the hybrid polymer tip compared with the metal balanced tip, as measured by cumulative dissipated energy (CDE) and total procedure time. SETTING: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah. DESIGN: Experimental study. METHODS: Phacoemulsification was performed with the Centurion Vision System and Infiniti OZil handpiece, with a 30-degree bevel metal balanced tip and hybrid polymer tip. The vacuum was set at 500 mm Hg and the aspiration flow rate at 50 mL/min. Power was changed for torsional and longitudinal ultrasound (US) at 20%, 40%, 60%, 80%, and 100%. Hardened porcine lenses were cut into 200 two mm cubes, 10 for each specified tip/power setting. They were placed into an artificial anterior chamber filled with a balanced salt solution, and phacoemulsification was performed. A second observer randomly assigned the US type and power. The same observer timed trials with a stopwatch, and CDE was recorded. RESULTS: There were no significant differences in time or CDE for any power levels or US modes when comparing the 2 tips. CONCLUSIONS: No significant difference in efficiency was observed when comparing the metal balanced tip with the hybrid polymer tip. Given the known improved safety profile and the overall equivalent efficiency of the hybrid tip, it could improve the performance of beginning and advanced surgeons in the future. Future study is needed to evaluate other setting combinations and to evaluate the hybrid tip in clinical settings.

RESUMO

Purpose: To understand the role of ophthalmic viscosurgical devices (OVDs) in corneal incision contracture (CIC). Specifically, the aim was to evaluate with the tip of the phacoemulsification needle free of OVD, how various OVDs near the tip and sleeve may transmit thermal energy to the incision site. Methods: A small chamber was filled with balanced saline solution (BSS), and a thin membrane was placed on the surface. OVD was placed atop the membrane. A temperature probe was placed in the OVD, while the handpiece pierced the membrane. The experiment was run both with and without flow and vacuum. Temperature measurements were gathered for each of the OVDs at four separate time points at 0 and 20mL/min flow. Results: As expected, there was a more pronounced temperature increase in all test groups with no fluid flow. While the temperature increase was not significantly different from BSS for any of the OVDs tested at either 0 or 20mL/min, Viscoat showed the most variable results at both flow settings. Conclusion: As long as the phaco tip is not in OVD, residual OVD near the incision is not exothermic and so not an additional risk for CIC.

RESUMO

Purpose: To determine the difference, if any, in grooving efficiency at various settings on the Whitestar Signature Pro phacoemulsification (phaco) system. Methods: Cataractous lenses were simulated by exposing porcine lenses to formalin for 2 hours. A total of 120 lenses were analyzed at various power settings on both longitudinal and transversal handpieces. Twenty trials each were performed with power set to 25%, 50%, and 75% on both handpieces. A Whitestar Phaco Handpiece System was used to provide longitudinal power, and a Whitestar Signature Ellipsis Handpiece provided transversal power. Lenses were placed within a plastic chamber and grooved by an investigator blinded to settings. A second investigator recorded times and adjusted settings. The Whitestar Signature Pro phaco system was used for grooving. Results: There was no significant difference in grooving times between the longitudinal and transverse handpieces at any power setting (P > 0.05). There was a significant decrease in grooving times when comparing the 25% power setting with the 75% power setting for the transversal handpiece (P=0.021). Conclusion: Both longitudinal and transversal handpieces on the Whitestar Signature Pro phaco system produce similar results to one another at each power setting. There is a general trend toward shorter grooving times, reflecting greater efficiency, at higher power settings. Grooving efficiency on the transversal handpiece may be more affected by changes in the power settings as compared with the longitudinal settings.

RESUMO

OBJECTIVE: To study the thermal properties and response magnitude of a forced-infusion phacoemulsification machine on 4 ophthalmic viscosurgical devices (OVDs). DESIGN: Experimental study. METHODS: A phacoemulsification tip, thermocouple, and gauge were placed into an artificial anterior chamber with balanced saline solution (BSS) or approximately 0.1 mL of OVD. Once the thermocouple measured a consistent temperature, the pedal was engaged for 60 seconds; then the tip was removed. The machine was cooled for 5 minutes and flushed with BSS to return to baseline. This was repeated 10 times for each OVD. The research consisted of 2 scenarios: vacuum-blocked flow rate and low aspiration flow rate. RESULTS: All OVDs showed greater temperature changes than BSS. In the vacuum-blocked scenario, these increases were statistically significant. The medium viscosity dispersive OVD (DiscoVisc) reached temperatures exceeding 60°C. In the low-flow scenario, HEALON5 and DisCoVisc were significantly different at 5 seconds and only HEALON5 at 10 seconds. No temperature increases over BSS were greater than 1.0°C. CONCLUSIONS: The dispersive, cohesive, and viscoadaptive OVDs demonstrated higher temperature changes than BSS but did not reach the threshold for corneal incision contracture. The study team verified the need for at least a minimal flow rate before ultrasound, which is especially evident in the first 10 seconds, because a flow rate of only 20 mL/minute mitigated OVD-related thermal effects. Understanding thermal responses enables corneal incision contracture risk reduction.

RESUMO

Purpose of Review: To describe the effect of COVID-19 on ophthalmic training programs and to review the various roles of technology in ophthalmology surgical education including virtual platforms, novel remote learning curricula, and the use of surgical simulators. Recent Findings: COVID-19 caused significant disruption to in-person clinical and surgical patient encounters. Ophthalmology trainees worldwide faced surgical training challenges due to social distancing restrictions, trainee redeployment, and reduction in surgical case volume. Virtual platforms, such as Zoom and Microsoft Teams, were widely used during the pandemic to conduct remote teaching sessions. Novel virtual wet lab and dry lab curricula were developed. Training programs found utility in virtual reality surgical simulators, such as the Eyesi, to substitute experience lost from live patient surgical cases. Summary: Although several of these described technologies were incorporated into ophthalmology surgical training programs prior to COVID-19, the pandemic highlighted the importance of developing a formal surgical curriculum that can be delivered virtually. Novel telementoring, collaboration between training institutions, and hybrid formats of didactic and practical training sessions should be continued. Future research should investigate the utility of augmented reality and artificial intelligence for trainee learning.

RESUMO

BACKGROUND: The use of cognitive-enhancing medications and supplements among healthy adults continues to rise. Limited data exists on their use among resident physicians. Given their highly competitive and stressful lifestyle, we sought to evaluate the prevalence, motivations, and side effects of using cognitive-enhancing supplements and medications among resident physicians at a large United States academic institution. METHODS: An anonymous web-based survey was circulated to resident physicians inquiring about using cognitive-enhancing supplements and medications, as well as personal characteristics such as gender, marital and parental status, medical diagnoses, and medical specialty. Before circulation, we performed a pilot study. Weighted logistic regression analyses estimated the impact of personal characteristics on the probability of using both supplements and medications. RESULTS: Survey response rate was 46.4%. Of respondents, 48.6% were female, 45.9% were married, 70.9% were without children, and 67.2% were in a non-surgical medical specialty. Few respondents had a related medical diagnosis, with attention deficit hyperactivity disorder being the most common (7.1%). Male, non-married, surgical residents were more likely to take supplements (odds ratio (OR) = 1.06, 1.05, and 1.05). Males, without children, and those who felt pressure to perform well, were afraid of being left behind, felt pressure because colleagues take them, or felt they could not reach their current level of training without medications were more likely to take medications (OR = 1.11, 1.04, 1.05, and 1.08). Adverse effects with medications were common. CONCLUSION: Supplement and medication use for cognitive enhancement was high among resident physicians at a single institution despite few having a related medical diagnosis. This study raises awareness of the growing pressure in competitive residency environments to use cognitive enhancement regardless of the potential side effects.

RESUMO

The Navajo Nation is the largest Native American reservation by area and citizenship. The study sought to provide the first large-scale examination of ocular pathology within this population. A retrospective review of all Navajo patients seen at Moran Eye Center Navajo Nation Outreach Clinics from 2013 to 2021 for demographics, visual acuity, refractive, and eye pressure data was undergone. Further variables included comorbidity and eye diagnoses among patients at these clinics. Results: First-time patient visits totaled 2251 from 2013 to 2021. The median age was 53 (range, 18 to 92), and clinics had a predominance of female patients (1387:864). Among patients presenting without glasses, 20.67% (198/958), 9.71% (93/958), and 3.13% (30/958) had mild visual impairment (VI), moderate to severe VI, and blindness, respectively. Cataracts were the most common cause of blindness in these patients (40%, 12/30) and the need for glasses was the second most common cause (33%, 10/30). From 2016 to 2021, 17.71% (48/271) of diabetic patients were diagnosed with diabetic retinopathy (DR). Within the subset of Navajo patients that presented without any correction, 73% of bilateral blindness was preventable via glasses prescription or cataract surgery. This study comments on questions of equitable care for Navajo patients.

RESUMO

Purpose: To determine the actual vacuum pressure generated by the Oertli CataRhex 3® (Oertli), using an external measuring system. Methods: The effective vacuum pressure created by the Oertli was measured with a pressure device that was continuous with the vacuum tubing system while closed to the external environment. Measurements were taken with the machine set to 300 and 500 mmHg at flow rates of 20, 35, and 50 mL/min and at bottle heights of 60, 80, and 100 cm. Pressures were recorded after the foot pedal was depressed to vacuum setting (second position), and the pressure was allowed to stabilize. Subsequently, it was compared to the pressure value displayed by the machine. Results: Externally measured vacuum pressure was on average 13.02% greater (39.05 mmHg) than displayed vacuum pressure at 300 mmHg (P < 0.005) and 8.60% greater (42.98 mmHg) than displayed vacuum at 500 mmHg (P < 0.005). The average difference between displayed and measured pressure increased with increasing bottle heights. Conclusion: On average, the vacuum pressure generated in the Oertli was found to be significantly higher than the machine's reading when the machine was set at 300 mmHg and 500 mmHg. Adjusting vacuum had variable effects on the measured versus displayed pressure readings.

RESUMO

PURPOSE: To describe gender representation at 8 national ophthalmology conferences, stratified by role, session category, and subspecialty. DESIGN: Retrospective cross-sectional study. METHODS: Data were examined on 3817 presenters at the 2019 American Academy of Ophthalmology subspecialty days, American Society of Cataract and Refractive Surgery, American Glaucoma Society, American Society of Retina Specialists, American Society of Ophthalmic Plastic and Reconstructive Surgery, American Association for Pediatric Ophthalmology and Strabismus, North American Neuro-Ophthalmology Society, and American Uveitis Society meetings. The main outcome measure was the gender of presenters in 7 subspecialties, stratified by category and role. RESULTS: The proportion of female presenters was less than the American Board of Ophthalmology (ABO)-estimated proportion of women in their respective fields in glaucoma (28.0% vs 39.8%), neuro-ophthalmology (35.3% vs 45.3%), and pediatrics (42.1% vs 53.3%) and greater than expected in retina (24.6% vs 19.8%). Overall, the proportion of female presenters exceeded the ABO-estimated proportion of women in ophthalmology (24.5%) for clinical (mean = 38.5%, 95% CI [35.8%, 41.4%]) and scientific (39.4% [30.3%, 49.2%]) sessions. For clinical subspecialty sessions, the proportion of female leaders exceeded the overall proportion of female leaders in the respective subspecialty in cornea (35.1% [30.4%, 40.1%] vs 24.6% all sessions). Females represented fewer than the expected number of surgical session leaders in cornea (22.0% [19.9%, 24.3%]), glaucoma (18.0% [13.2%, 24.1%]), pediatrics (22.0% [14.4%, 32.1%]), and retina (18.6% [14.2%, 24.1%]). CONCLUSIONS: Gender representation varied, with fewer than expected female presenters in glaucoma, neuro-ophthalmology, and pediatrics. Women led relatively more clinical sessions but were underrepresented in surgical sessions in most subspecialties.

RESUMO

Purpose: To evaluate the effect of each of the tip sizes available for the Oertli CataRhex3® phacoemulsification machine on efficiency. Methods: Porcine lenses were fixed in formalin for 2 hours, then cut into 3.0 mm cubes. We studied three Oertli tips, all of which had a 30-degree bevel: easyTip 2.2 mm (20G), easyTip 2.8 mm (19G), and CO-MICS (21G). For the 19G and 20G tips, vacuum was set at 600 mmHg, irrigation rate at 50 mL/min, continuous power 70%, and bottle height 85 cm. For the 21G tip, vacuum was set at 450 mmHg; irrigation and power settings were identical to those used for the easyTip tips. We measured time to removal and chatter events to determine efficiency. Results: Results from 20 trials for each tip showed that the larger the gauge size, the more quickly lens fragments were removed. Chatter events demonstrated an increasing trend with smaller tip gauge. The 19G tip used an average time to fragment removal of 2.8 seconds; the 20G, 3.2 seconds; and the 21G, 4.6 seconds. Increasing tip diameter from 21G to 20G decreased emulsification time by 33% (P = 0.02). Increasing the diameter from 21G to 19G further decreased time to emulsification by 42% (P = 0.003). The 21G tip had a mean 1.4 events/cube; 20G, 0.35 events; and 19G, 0.1 events. Differences in mean chatter events for each tip were each statistically significant. Conclusion: These data suggest that when evaluated by chatter events and emulsification time, the 2.8 mm (19G) easyTip proves to have greatest efficiency.

RESUMO

Purpose The aim of this study was to assess efficacy of a virtual, double-flipped clinical rotation in ophthalmology for medical students during the coronavirus disease 2019 (COVID-19) pandemic. Methods We instituted a virtual, reverse-classroom clinical elective for eight medical students interested in ophthalmology as a career. The course included required prework, interactive case-based discussions, and follow-up quizzes (first flip) entirely prepared and delivered by the students as teachers (second flip). After completion of the course, we surveyed students on five domains: (1) Autonomy and Leadership, (2) Self-Efficacy, (3) Impact on Career Selection, (4) Quality of Educational Experience, and (5) Clear Goals and Feedback using a Likert scale of 1-5 (5 being the most positive). We also asked open-ended questions regarding the overall experience, that is, strengths, weaknesses, and future recommendations for the course. Due to the small N and exploratory nature of the study, no formal statistical inference was performed. Results Seven students responded to the survey. Aggregated mean survey scores for each domain are represented in parentheses. Responses were very positive in regard to "Autonomy and Leadership" (4.5), "Impact on Career Selection" (4.1), "Quality of Educational Experience" (5.0), and "Clear Goals and Feedback" (4.4). "Self-Efficacy," which had an emphasis on ability to perform an eye exam and basic knowledge of ophthalmology, had a lower mean (3.4). The subjective responses were also very positive, but similarly alluded to the limitation of learning examination skills virtually. Conclusions A medical school clinical elective can be successfully executed in a virtual format with an emphasis on student-directed learning. The novel "double-flipped" approach was highly rated by our small sample size. However, there remained a glaring limitation in the ability to transfer clinical skills in the virtual format. In the context of limited in-person contact due to the COVID-19 pandemic, we believe that the double-flipped, virtual format was a viable replacement for a traditional clinical rotation.

RESUMO

OBJECTIVE: Examine underrepresented minority (URM) recruitment and diversity education initiatives provided by residency programs in ophthalmology and other specialties, and identify means to support programs as they work to enhance diversity efforts. DESIGN: Cross-sectional study. SETTING: Multi-center survey of residency program leadership of the Association of University Professors of Ophthalmology, Johns Hopkins Medicine, University of Utah, and the University of California, Los Angeles. PARTICIPANTS: Residency program leadership (i.e., residency program directors and associate residency program directors) RESULTS: Our survey response rate was 34% (63/188); 56% percent of responses were from ophthalmology and 44% were from other specialties. Across all specialties, programs with a large number of clinical faculty and trainees were associated with having ≥1 URM resident in their program (p = 0.026 and p = 0.028, respectively). There was no significant difference between ophthalmology and other specialties with regard to the number of URM residents. Ninety-two percent of programs utilized strategies to recruit URM applicants. While certain strategies were more common for ophthalmology than other specialties, information sessions for URM students (62%) and a unique review of all URM residency applicants by a separate committee/person (46%) were most commonly used overall. Although 92% of residency program leadership believed it was highly important for health professionals to receive formal diversity training, only 54% of programs had a diversity education curriculum for both trainees and faculty, 11% had a curriculum for faculty only, and 3% had a curriculum for trainees only. Barriers to implementation of curricula included lack of faculty expertise (30%) and curricular time (30%). CONCLUSIONS: An overwhelming majority of programs in our study utilized strategies to recruit URM applicants, but 22% had 0 URM residents in their program. To address the reported barriers to diversity education implementation, shared central resources/diversity education toolkits should be created to provide programs with needed support.

RESUMO

PURPOSE: We assessed the effect of two lens cube sizes, three tip sizes, and two ultrasound (US) approaches on phacoemulsification efficiency and chatter. METHODS: After porcine lens nuclei were soaked in formalin, we divided them into cubes measuring 2.0 mm or 3.0 mm. We collected efficiency and chatter data for 30-degree bent 19 G, 20 G, and 21 G tips with a continuous torsional US system; and for straight 19 G, 20 G, and 21 G tips with a micropulse longitudinal US system. RESULTS: The average time needed for removal was always higher for the 3.0 mm lens cube than for the 2.0 mm lens cube. Statistically significant differences were observed between the 19 G and 21 G tips with micropulse longitudinal US using a 2.0 mm cube and a 3.0 mm cube, and with continuous transversal US using a 2.0 mm lens cube and a 3.0 mm cube. We did not observe significant differences between 19 G and 20 G tips with either cube size in either US system. However, we noted identical trends for both cube sizes with both US approaches; 19 G tips performed better than 20 G and 21 G tips. CONCLUSION: Regardless of the lens size, 19 G needles were the most efficient, and had both the fewest outliers and the smallest standard deviations.

RESUMO

This study was designed to determine the effect of a novel simulation-based training curriculum for scleral tunnel construction in manual small incision cataract surgery (MSICS) compared with traditional training. In this multicenter, investigator-masked, randomized clinical trial, resident surgeons within 3 months of matriculation with minimal or no prior experience with MSICS were assigned either to simulation-based training, the Experimental Group (EG), or to conventional training, the Control Group (CG). EG residents were trained to perform scleral tunnel construction using a simulation-based curriculum (HelpMeSee Eye Surgery Simulator), while residents in the CG followed institution-specific curriculum before progressing to live surgery. Surgical videos of the first 20 attempts at tunnel construction were reviewed by masked video raters. The primary outcome was the total number of any of 9 pre-specified errors. On average, the total number of errors was 9.25 (95% CI 0-18.95) in the EG and 17.56 (95% CI 6.63-28.49) in the CG (P = 0.05); the number of major errors was 4.86 (95% CI 0.13-9.59) in the EG and 10.09 (95% CI 4.76-15.41) in the CG (P = 0.02); and the number of minor errors was 4.39 (95% CI 0-9.75) in the EG and 7.47 (95% CI 1.43-13.51) in the CG (P = 0.16). These results support that novice surgeons trained using the novel simulation-based curriculum performed fewer errors in their first 20 attempts at tunnel construction compared to those trained with a conventional curriculum.

RESUMO

Background In the setting of the COVID-19 pandemic, residency programs implemented videoconferencing "virtual" interviews for the 2020 to 2021 match cycle. There is limited published information on virtual ophthalmology residency interviews. Objective The study aimed (1) to assess applicant, selection committee member, and resident opinions of technical quality, communication quality, and ability to assess applicant or program "fit" during virtual interviews; (2) to determine which interview format-in-person or virtual-each party would prefer in the future; and (3) to survey which residency resources applicants found helpful. Design Surveys were sent to applicants, selection committee members, and residents to assess the above objectives for the 2020 to 2021 match cycle virtual interviews at the Moran Eye Center, University of Utah. Setting This study was conducted in a single residency program interview season from 2020 to 2021. Participants Forty applicants, eight committee members, and seven residents who participated in the virtual interview process were surveyed. Intervention or Exposure Prior to interviews, various avenues were implemented to connect with applicants. A videoconferencing software was utilized for interviews. Applicants and selection committee members met in one-on-one or small group interviews. Residents communicated with applicants in a large group setting between interviews. Main Outcome and Measure The study aims to survey the participants as stated in the objectives. There was no planned outcome for this quality improvement study. Results Survey response rate was 98.2% (54/55). All parties rated the technical components as good or very good. Applicants and selection committee members rated communication as overall good or very good, although residents thought communication was very poor. A total of 92.3% applicants, 75% selection committee members, and 0% residents were reported that they were able to appropriately assess fit of the program with the applicant. However, 46.3% respondents preferred in-person interviews in the future. Popular applicant resources were resident-produced videos (82.1%), conversations with residents (46.2%), and a gift bag (43.6%). Conclusion and Relevance Overall, the technical components of the interview were successful. Small, structured group interactions led to better communication and assessment of fit. There were variable opinions regarding future interview format preference between in-person, virtual, or choice. Amid the COVID-19 pandemic, connecting with applicants via various means can optimize the match process.

RESUMO

Objective This study assesses a new departmental role-a professionalism mentor-who receives sexual harassment reporting, liaisons with campus resources, and organizes educational sessions. Study Design Multicenter randomized controlled survey study. Methods Academic ophthalmology departments in the United States were randomized to a professionalism mentor group ( n = 9) and a control group ( n = 7). Among both pre- and postsurveys, 605 faculty and trainee responses were received and 546 were complete. The intervention group was assigned a professionalism mentor with educational session for a 6- to 10-month period. Sexual harassment and reporting rate change over time were compared between the two groups. Results Among 546 anonymous responses, 16% experienced workplace sexual harassment during the prior 10 months. Location in the South or Midwest was a risk factor ( p < 0.001). Victims were mostly women (76%), including residents/fellows (46%) and academic attendings (49%); perpetrators included patients (35%) and academic attendings (35%). Departments with and without a professionalism mentor had stable harassment from pre- to postsurvey ( p = 0.95 comparing change). The professionalism mentor group had an increase in reporting to an authority from pre- to postsurvey (7-23%), whereas the control group had a decrease (27-12%; p = 0.07 comparing change). Most faculty and trainees in the interventional arm of this study recommended instituting a professionalism mentor with educational session (66% presurvey and 68% postsurvey), compared with educational session alone (25% presurvey and 23% postsurvey), or neither (9% presurvey and 9% postsurvey). Residency program directors in the professionalism mentor group even more strongly supported instituting both a professionalism mentor and educational program (100% presurvey and 100% postsurvey) as opposed to educational program alone (0% presurvey and 0% postsurvey) or neither (0% presurvey and 0% postsurvey). Conclusion This study identified a high sexual harassment rate in academic ophthalmology departments over a brief period. The presence of a professionalism mentor was viewed favorably and may lead to increased reporting.
