Disparities in cataract surgical training at the University of Toronto based on sex and medical school graduate type.

Objective: To compare sex and medical school graduate type differences in cataract surgical training volumes at Canada's largest residency program, the University of Toronto (UoT).

Design: Retrospective cohort study PARTICIPANTS: Ophthalmology residents completing cataract surgical training from 2015 to 2020.

Methods: Data collected from surgical logbooks at the main cataract surgical teaching site at UoT were analyzed from July 1, 2015, to June 30, 2020. Data collected included stage of resident training and degree of participation for each case. The main outcome measure was mean number of complete cataract cases as a function of resident sex, medical school graduate type, and level of training.

Results: Thirty-five (19, 54.3% female) residents completed cataract surgical training during the study period. There were 24 (68.6%) Canadian medical graduates (CMGs) and 11 (31.4%) international medical graduates (IMGs). Female residents performed a lower mean number of complete cataract cases compared to males (464.2 versus 504.8, respectively). IMGs completed on average 110.0 (22.8%) fewer cataract cases compared to CMGs. Compared to all residents, female IMGs had the lowest number of complete cataract cases (mean of 380.8 versus 465.7, respectively). The greatest difference occurred between male CMGs and female IMGs, with male CMGs performing 153.8 (40.4%) more complete cases (534.6 vs 380.8, respectively).

Conclusion: The greatest difference in surgical volumes occurred between CMGs and IMGs. Female IMGs had the lowest complete cataract case volumes compared to all residents. Our study highlights novel medical school graduate type disparities in cataract surgical training warranting further exploration.
