Abstract

PURPOSE: To investigate how experience in simulated cataract surgery impacts and transfers to the learning curves for novices in vitreoretinal surgery.

METHODS: Twelve ophthalmology residents without previous experience in intraocular surgery were randomized to (1) intensive training in cataract surgery on a virtual-reality simulator until passing a test with predefined validity evidence (cataract trainees) or to (2) no cataract surgery training (novices). Possible skill transfer was assessed using a test consisting of all 11 vitreoretinal modules on the EyeSi virtual-reality simulator. All participants repeated the test of vitreoretinal surgical skills until their performance curve plateaued. Three experienced vitreoretinal surgeons also performed the test to establish validity evidence. Analysis with independent samples t-tests was performed.

RESULTS: The vitreoretinal test on the EyeSi simulator demonstrated evidence of validity, given statistically significant differences in mean test scores for the first repetition; experienced surgeons scored higher than novices (p = 0.023) and cataract trainees (p = 0.003). Internal consistency for the 11 modules of the test was acceptable (Cronbach's α = 0.73). Our findings did not indicate a transfer effect with no significant differences found between cataract trainees and novices in their starting scores (mean ± SD 381 ± 129 points versus 455 ± 82 points, p = 0.262), time to reach maximum performance level (10.7 ± 3.0 hr versus 8.7 ± 2.8 hr, p = 0.265), or maximum scores (785 ± 162 points versus 805 ± 73 points, p = 0.791).

CONCLUSION: Pretraining in cataract surgery did not demonstrate any measurable effect on vitreoretinal procedural performance. The results of this study indicate that we should not anticipate extensive transfer of surgical skills when planning training programmes in intraocular surgery.
