Methods
The study was performed in accordance with the US Health Insurance Portability and Accountability Act of 1996, and an investigational review board exemption was granted by the Office of the Human Research Protection Program at Harbor-UCLA Medical Center and Los Angeles Biomed.
The Eyesi ophthalmic microsurgical simulator with software versions 2.4 and 2.5 was used during the study. A Capsulorhexis Intensive Training Curriculum (CITC) was developed by one of the study authors (C.A.M.). The
Results
During the study, 38 residents performed surgery at Harbor-UCLA Medical Center, and because of the sequential nature of the study years and residency training, many of them contributed to more than 1 PGY or cohort. The baseline cohort consisted of 25 residents, who contributed to the cohort as PGY 2 (3 residents), PGY 3 (15 residents), and PGY 4 (14 residents). In the postintervention cohort, there were 23 residents who contributed to the cohort as PGY 3 (16 residents) and PGY 4 (16 residents).
Discussion
The introduction of the CITC on the Eyesi virtual reality ophthalmic microsurgical simulator was associated with a statistically significant 68%, or 3.2-fold, reduction in errant capsulorhexis rates among ophthalmology residents performing cataract surgery at a teaching hospital. Furthermore, in the baseline cohort, there were fewer errant CCCs among the group of PGY 4 residents compared with the group of PGY 3 residents (Fig 2). In contrast, the post-intervention cohort showed no difference in
