Risk factors for complications in resident-performed cataract surgery: A systematic review.

We assessed risk factors for complications associated with resident-performed cataract surgery. Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, we searched 4databases in September, 2023. We included peer-reviewed, full-text, English-language articles assessing risk factors for complications in resident performed cataract surgery. We excluded studies describing cataract surgeries performed by fellows, combined surgeries, and studies with insufficient information. Our initial search yielded 6244 articles; 15 articles were included after title/abstract and full-text review. Patient-related risk factors included older age, hypertension, prior vitrectomy, zonular pathology, pseudoexfoliation, poor preoperative visual acuity, small pupils, and selected types of cataracts. Surgeon-related risk factors included resident postgraduate year and surgeon right-handedness. Other risk factors included absence of supervision, long phacoemulsification time, and phacoemulsification with high power and torsion. The quality of the studies was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation; most studies graded as moderate, primarily due to risk of bias. When assigning cases to residents, graduate medical educators should consider general and resident-specific risk factors to facilitate teaching and preserve patient safety.

Preclinical training of future ocular surgeons: a French opinion-based study.

PURPOSE: To assess ophthalmology residents satisfaction regarding surgical training during residency in France. METHODS: A questionnaire consisting of 28 questions was designed and sent to residents of ophthalmology across the 27 French regions. RESULTS: A total of 30.3% ophthalmology residents in France completed our questionnaire. All French regions participated. They rated 5,27 ± 2.42/10 the global surgical training during residency. They had performed at least one step of any type of ocular surgery for 93.4% of them, while 80.7% had completed at least one full cataract surgery, by the beginning of their second year of residency on average (Paris: 2.59 ± 1.36 semesters; regions: 4.05 ± 1.96 semesters, p < 0.0001). Only 48.9% identified a surgical mentor during their residency, but 82.2% did not clearly identify surgical goals & objectives during their training. Simulation was available for any type of ocular surgery to all residents in the Paris (Île-de-France) region and to 78.1% in other regions (p < 0.005). Residents who accessed drylabs and wetlabs gave a satisfaction score of 7.31 ± 1.89/10 and 6.39 ± 2.15/10 to it respectively. Simulation was a mandatory part of the curriculum for 35.2% of the resident. They commented on on reduced access to subspecialized surgery. They were willing for more access to simulation and surgery on real patients, as well for closer mentoring and clearly defined surgical goals within the curriculum. CONCLUSION: Ophthalmology residents seemed globally satisfied with their surgical training nationwide, although we observed disparities across region. They largely acknowledged a lack of standard procedures nationwide. They acclaimed simulation during the initial phase of residency, progressively switching towards surgery on real patients. An "operating license" during residency could be a viable way for the resident to demonstrate that they have acquired enough surgical abilities to perform surgery on real patients.

Cataract surgical training in Europe: European Board of Ophthalmology survey.

PURPOSE: To survey recently graduated European ophthalmologists concerning cataract surgery (CS) training opportunities. SETTING: Countries affiliated to the European Board of Ophthalmology (EBO). DESIGN: Cross-sectional study of anonymous survey results. METHODS: A 23-question online survey was emailed to candidates who sat the EBO Diploma Examination as residents between 2018 and 2022. RESULTS: 821 ophthalmologists from 30 countries completed the survey. The mean residency duration was 4.73 (SD 0.9) years. The mean reported number of entire CS procedures performed was 80.7 (SD 100.6) at the end of residency, but more than 25% of respondents (n = 210) had received no live CS training during their residency. The self-confidence (scale, 1 to 10) to perform a simple case or challenging case, manage posterior capsular rupture, and realize a corneal stitch were rated 4.1, 3.2, 4.2, 2.4, respectively. We observed extensive variation in clinical exposure to CS and self-reported confidence to perform CS between European trainees. Females reported a mean of 18% fewer entire procedures than their male colleagues and were also less confident in their surgical skills (P < .05). Trainees in residency programs longer than 5 years performed fewer procedures and were less confident than trainees in residences of shorter duration (P < .001). The importance of fellowships to complete surgical education was rated 7.7 out of 10. CONCLUSIONS: CS training across European countries lacks harmony. Female ophthalmology trainees continue, as in other specialties, to experience apparent gender bias. European level recommendations seem necessary to raise and harmonize competency-based CS training programs and promote post-residency fellowship training programs.

Harmonizing ophthalmic residency surgical training across Europe: A proposed surgical curriculum.

BACKGROUND: One of the core aims of the European Union of Medical Specialists is to harmonize training across Europe by creating European Training Requirements for all medical specialties including Ophthalmology. The theoretical part is already defined by the EBO, however as ophthalmology also includes surgical skills, we herein propose a surgical minimum curriculum for ophthalmology residents in Europe. METHODS: National and international ophthalmic training curricula which are publicly available in English were reviewed and compared. The final proposal was created from 5 criteria: 1. Disease prevalence; 2. Patient safety; 3. Case-trainee ratio; 4. Skill transfer; and 5. Technical difficulty. RESULTS: In total 7 different training curricula from across the world were compared. Among the surgical procedures, cataract surgery has the highest median number of procedures required to be completed during residency: 86 procedures (50-350). Followed by oculoplastics: 28 procedures (10-40) and panretinal photocoagulation: 27.5 procedures (10-49) Full procedural competence is proposed in 9 surgical skills, including YAG laser posterior capsulotomy, retinal argon laser, intravitreal injection, corneal foreign body removal, removal of corneal sutures, facial and periocular laceration repair, eyelid laceration repair, minor eyelid procedures, and punctal occlusion. These procedures are deemed essential and feasible for all ophthalmology residents in Europe to perform independently upon completion of their training. CONCLUSION: This proposal should be regarded as a recommendation based on comparable surgical curricula in use worldwide to establish standards across European countries and may serve as valuable insight to those responsible for compiling ETRs for ophthalmology, or their national curriculums.

Patient perspective on the participation of ophthalmology residents in their cataract surgery.

OBJECTIVE: To determine the proportion of patients consenting to resident participation in cataract surgery and to identify factors predictive of consent. DESIGN: Prospective cross-sectional study. PARTICIPANTS: The 330 consecutive patients referred for cataract evaluation from February-April 2021 to 3 surgeons at a tertiary care referral centre in London, Ontario. METHODS: Using a standardized disclosure script, individuals were asked about resident participation in their cataract surgery. A phone survey and medical record review were conducted to obtain clinical and demographic information. Predictors of consent were assessed using logistic regression modelling. RESULTS: Responses were received from 279 individuals (85% response rate), with a mean age of 71.7 ± 8.6 years, and 113 were female. The consent rate was 71%. Prior negative experience with any medical trainee was an independent predictor for refusing resident participation (odds ratio [OR] = 3.10; 95% CI, 1.32-7.28; p = 0.009). Nonconsenters also had more prior negative experiences with other physicians (35% vs 23%; p = 0.031) and knew someone who had had a problem after eye surgery (36% vs 22%; p = 0.016). Individuals with an occupation involving apprenticeship (OR = 2.87; 95% CI, 1.08-7.67; p = 0.035) and those with a preoperative acuity of 20/200 or worse (OR = 2.78; 95% CI, 1.03-7.14; p = 0.043) were more likely to consent. CONCLUSIONS: Patients should be explicitly asked about resident involvement. Negative experiences can make individuals reluctant to have learners involved in their future care. Patient education describing the apprenticeship model in medicine may increase consent.

Incidence of re-surgery after manual small-incision cataract surgery at a tertiary eye-care center in South India.

Purpose: To study the incidence of re-surgery after manual small-incision cataract surgery (MSICS) at a tertiary eye-care center in South India and to compare the re-surgery rate between trainees and experts. Methods: A retrospective study was conducted at a tertiary eye-care center in Andhra Pradesh state of South India, which included 19,515 patients who underwent MSICS between 2012 and 2022 with 369 eyes of 369 patients who underwent re-surgery within 1 week of primary surgery. Factors included demographic data, type of re-surgery, that is, wound re-suturing, IOL repositioning, cortical wash, as well as anterior chamber (AC) wash. Results: 19,515 eyes from the year 2012-2022 were analyzed. Most of the patients undergoing re-surgery belonged to the age group of 61-70 years (40.3%). Wound re-suturing was the more frequently performed re-surgery (47.6%). Wound re-suturing rates were comparable between the trainees and experts, whereas IOL repositioning, cortical wash, and AC wash were higher in the cases performed by trainees though statistically not significant. Conclusion: Careful pre-operative assessment, training under supervision, and other measures can be taken to reduce the re-surgery rates. Timely diagnosis and early treatment can give better outcomes and prevent devastating complications like endophthalmitis.

Embracing technology in cataract surgical training - The way forward.

While ophthalmology as a surgical branch itself has evolved technologically with newer instruments, techniques and procedures; ophthalmic surgical training appears to have stagnated in terms of how it is delivered and how trainees' learning and performance are assessed. This collaborative editorial attempts to identify the lacunae in ophthalmic residency training and highlight how technological tools such as surgical simulators can be incorporated into ophthalmic training even in limited-resource settings with good results.

Impact of COVID-19 on surgical specialist training as quantified by trainee complication rates for cataract surgery.

BACKGROUND: Reduction in elective surgeries during the COVID-19 pandemic has negatively impacted surgical specialist training. Posterior capsule rupture rate (PCR), a complication of cataract surgery, is an objective measure of the quality of ophthalmic surgery. This study aimed to compare PCR pre- and post-COVID-19 in trainees and consultants. METHODS: A single-centre consecutive cases series of cataract surgeries performed at Groote Schuur Hospital, between 1 February 2017 and 31 May 2021 were analysed. Our main outcome measure was the effect of the volume of cataract surgeries on PCRs between ophthalmology trainees and consultants before and after the COVID-19 reduction in elective surgeries on 23 March 2020. RESULTS: During the study period, 4 157 cataract surgeries were performed (3 493 in the 38 months pre-COVID-19 and 664 in the 14 months post-COVID-19). Fourteen ophthalmology trainees and six consultants performed 2 919 and 1 238 cataract surgeries, respectively. In the trainees the PCR was 4.4% pre-COVID-19 and 10.0% post-COVID-19 (odds ratio [OR] 2.44; p < 0.001; CI 1.71-3.47; relative risk [RR] 2.29). The PCR of consultants remained unchanged with a PCR of 3.4% pre- and post-COVID-19 (OR 1.02; p = 0.97; CI 0.42-2.46; RR 1.02). CONCLUSION: COVID-19 has caused a marked reduction in the volume of cataract surgery which has resulted in a deterioration in the performance of trainees, but not consultants, and quantifies the negative impact of the pandemic on surgical training in ophthalmology. This highlights the need to develop plans to improve surgical training during the COVID-19 recovery period.

The impact of distance cataract surgical wet laboratory training on cataract surgical competency of ophthalmology residents.

BACKGROUND: This study assessed the impact of distance cataract surgical wet laboratory training on surgical competency of ophthalmology residents at a tertiary-level ophthalmic training center in Trujillo, Peru. METHODS: Three five-week distance wet lab courses were administered through Cybersight, Orbis International's telemedicine platform. Weekly lectures and demonstrations addressed specific steps in phacoemulsification surgery. Each lecture had two accompanying wet lab assignments, which residents completed and recorded in their institution's wet lab and uploaded to Cybersight for grading. Competency was assessed through anonymous grading of pre- and post-training surgical simulation videos, masked as to which occurred before and after training, using a standardized competency rubric adapted from the Ophthalmology Surgical Competency Assessment Rubric (OSCAR, scale of 0-32). Day one best-corrected post-operative visual acuity (BVCA) was assessed in the operative eye on the initial consecutive 4-6 surgeries conducted by the residents as per the norms of their residency training. An anonymous post-training satisfaction survey was administered to trainees'. RESULTS: In total, 21 ophthalmic residents participated in the courses, submitting a total of 210 surgical videos. Trainees' average competency score increased 6.95 points (95%CI [4.28, 9.62], SD = 5.01, p < 0.0001, two sample t-test) from 19.3 (95%CI [17.2, 21.5], SD = 4.04) to 26.3 (95%CI [24.2, 28.3], SD = 3.93). Visual acuity for 92% of post-training resident surgeries (n = 100) was ≥20/60, meeting the World Health Organization's criterion for good quality. CONCLUSIONS: Structured distance wet lab courses in phacoemulsification resulted in significantly improved cataract surgical skills. This model could be applicable to locations where there are obstacles to traditional in-person training, such as the current COVID-19 pandemic.

Intense Simulation-Based Surgical Education for Manual Small-Incision Cataract Surgery: The Ophthalmic Learning and Improvement Initiative in Cataract Surgery Randomized Clinical Trial in Kenya, Tanzania, Uganda, and Zimbabwe.

Importance: Cataracts account for 40% of cases of blindness globally, with surgery the only treatment. Objective: To determine whether adding simulation-based cataract surgical training to conventional training results in improved acquisition of surgical skills among trainees. Design, Setting, and Participants: A multicenter, investigator-masked, parallel-group, randomized clinical educational-intervention trial was conducted at 5 university hospital training institutions in Kenya, Tanzania, Uganda, and Zimbabwe from October 1, 2017, to September 30, 2019, with a follow-up of 15 months. Fifty-two trainee ophthalmologists were assessed for eligibility (required no prior cataract surgery as primary surgeon); 50 were recruited and randomized. Those assessing outcomes of surgical competency were masked to group assignment. Analysis was performed on an intention-to-treat basis. Interventions: The intervention group received a 5-day simulation-based cataract surgical training course, in addition to standard surgical training. The control group received standard training only, without a placebo intervention; however, those in the control group received the intervention training after the initial 12-month follow-up period. Main Outcomes and Measures: The primary outcome measure was overall surgical competency at 3 months, which was assessed with a validated competency assessment rubric. Secondary outcomes included surgical competence at 1 year and quantity and outcomes (including visual acuity and posterior capsule rupture) of cataract surgical procedures performed during a 1-year period. Results: Among the 50 participants (26 women [52.0%]; mean [SD] age, 32.3 [4.6] years), 25 were randomized to the intervention group, and 25 were randomized to the control group, with 1 dropout. Forty-nine participants were included in the final intention-to-treat analysis. Baseline characteristics were balanced. The participants in the intervention group had higher scores at 3 months compared with the participants in the control group, after adjusting for baseline assessment rubric score. The participants in the intervention group were estimated to have scores 16.6 points (out of 40) higher (95% CI, 14.4-18.7; P < .001) at 3 months than the participants in the control group. The participants in the intervention group performed a mean of 21.5 cataract surgical procedures in the year after the training, while the participants in the control group performed a mean of 8.5 cataract surgical procedures (mean difference, 13.0; 95% CI, 3.9-22.2; P < .001). Posterior capsule rupture rates (an important complication) were 7.8% (42 of 537) for the intervention group and 26.6% (54 of 203) for the control group (difference, 18.8%; 95% CI, 12.3%-25.3%; P < .001). Conclusions and Relevance: This randomized clinical trial provides evidence that intense simulation-based cataract surgical education facilitates the rapid acquisition of surgical competence and maximizes patient safety.

The influence of surgeons and technicians on the learning curve of femtosecond-laser cataract surgery / Influencia de los cirujanos y técnicos en la curva de enseñanza de la cirugía de cataratas con láser de femtosegundo

PURPOSE: To demonstrate the influence of the surgeon's and the operating room (OR) technicians' experience upon the outcome of femtosecond laser-assisted cataract surgery (FLACS). MATERIALS AND METHODS: Our study included 250 eyes from 156 patients who had undergone either cataract surgery or clear-crystalline-lens extraction and where capsulorhexis and lens fragmentation had been performed using the CATALYS® Precision System femtosecond platform (Abbott Medical Optics Inc., Santa Ana, CA, USA).The patients were operated either by an experienced surgeon in the use of femtosecond laser or by an inexperienced surgeon in that field and two technicians. The quantitative outcome measures were: Suction loss rate, vacuum time, number of consumables used by the patient and intraoperative complication rate. RESULTS: Both for the experienced and the inexperienced surgeons, suction loss rates as well as vacuum time decreased progressively as time went by and more surgical procedures had been completed by that surgeon. For a given surgeon suction time decreased significantly, going from 137 to 99s, as the assisting technician gradually gained experience. The number of consumables used in each procedure by the experienced surgeon ranged from 1.10 (for the first 50 cases) to 1.02 from those initial cases onwards. Regarding intraoperative complications, they also decreased progressively as the number of procedures completed by the surgeon increased. CONCLUSIONS: The experience of each team member involved in such procedures-be it surgeons or technicians-have an impact, to a greater or lesser extent, upon the surgery's outcome, as quantified by the outcome variables of choice

OBJETIVO: Demostrar la influencia de la experiencia del cirujano y los técnicos de quirófano en los resultados de la cirugía de cataratas asistida por láser de femtosegundo (FLACS). MATERIALES Y MÉTODOS: Nuestro estudio incluyó 250 ojos de 156 pacientes sometidos a cirugía de cataratas o extracción de cristalino transparente, en las que la capsulorrexis y la fragmentación de lente se habían realizado utilizando la plataforma de femtosegundo CATALYS(R) Precision System (Abbott Medical Optics Inc., Santa Ana, CA, EEUU). Los pacientes fueron operados, bien por un cirujano con experiencia en el uso del láser de femtosegundo, o bien por un cirujano sin experiencia en dicho campo, y dos técnicos. Las medidas del resultado cuantitativo fueron: tasa de pérdida de succión, tiempo de vacío, número de consumibles utilizados por el paciente, y tasa de complicación intraoperatoria. RESULTADOS: Tanto para cirujanos expertos como inexpertos, las tasas de pérdida de succión, así como el tiempo de vacío disminuyeron progresivamente a medida que transcurría el tiempo, y que se incrementaba el número de intervenciones quirúrgicas completadas por el cirujano. Para un cirujano dado, el tiempo de succión disminuyó significativamente, pasando de 137 a 99 segundos, a medida que el técnico asistente ganaba experiencia gradualmente. El número de consumibles utilizados en cada procedimiento por un cirujano experto oscilaba entre 1,10 (para los primeros 50 casos) y 1,02 desde los casos iniciales en adelante. En cuanto a complicaciones intraoperatorias, también disminuyeron progresivamente a medida que aumentaba el número de intervenciones completadas por el cirujano. CONCLUSIONES: La experiencia de cada miembro del equipo involucrado en dichos procedimientos-bien fueran cirujanos o técnicos-tiene un impacto, en mayor o menor medida, sobre el resultado de la cirugía, según lo cuantificado por las variables de elección del resultado

Simulation of advanced cataract surgery - validation of a newly developed test.

PURPOSE: To develop and investigate an Eyesi simulator-based test for the more experienced cataract surgeon for evidence of validity. METHODS: The study was a prospective interventional cohort study and carried out at the Copenhagen Academy for Medical Education and Simulation. The Eyesi Simulator was used for the test which was developed by three expert cataract surgeons. Ten cataract surgeons (>250 surgeries performed) and ten ophthalmic residents performed two repetitions of the test. The test consisted of four modules: Iris Expansion Ring insertion - level 1, Iris Expansion Ring extraction - level 2, Capsulorhexis - level 3 and Anterior Vitrectomy - level 6. RESULTS: Internal consistency reliability showed Cronbach's alpha of 0.63. Test-retest reliabilities were significant for Iris Expansion Ring extraction - level 2 (p = 0.012) and Capsulorhexis - level 3 (p = 0.018). Differences between the two groups were only significant in both repetitions for the Iris Expansion Ring extraction - level 2 (p < 0.001 and p = 0.041, respectively). Furthermore, we found a statistically significant difference between the mean module scores for novices and the more experienced surgeons for Iris Expansion Ring insertion - level 1 (p = 0.021) and Capsulorhexis - level 3 (p = 0.019) in the first repetition. CONCLUSION: The investigated modules show evidence of validity within several aspects of Messick's framework. However, the evidence is not strong enough to apply the test for certification purposes of cataract surgeons, but the modules may still be relevant in the training of advanced cataract surgical procedures.
