“…With the advent of virtual reality simulators it is now possible to study the effects of different conditions on surgical outcomes without compromising patient safety [7][8][9][10]. Simulators have been used to study how distractions can influence surgical outcomes [11], including during intraocular procedures involving the anterior segment by Park et al [7].…”

Purpose To determine the effect of distraction on posterior segment surgical performance using a virtual reality simulator in expert and novice ophthalmic surgeons. Methods Twenty subjects were given 6 min to read an unpublished research paper and then were randomized into two groups. Group 1 subjects were allowed 3 min to complete a standardized vitreoretinal simulated task undistracted. Group 2 subjects were asked six questions on the research paper whilst completing the same task. Each subject then performed the alternate scenario. Finally, all participants were asked six questions on the research paper whilst not operating. Results There was no evidence of a difference in the odometer values (p = 0.127), cognitive task score (p = 0.390) or overall surgical task scores (p = 0.113) between the two groups. The time taken by the distracted group was significantly greater (95% CI −26.03 to −1.67, t-test p = 0.028). Conclusion Distraction significantly increases the time taken to perform a simulated vitreoretinal surgical task for all grades of surgeon. More studies are required to understand the impact on different types of distraction on surgical performance.

“…2 Recent studies have demonstrated that a decreased stereoacuity results in a statistically significant decrease in simulated surgical performance for most participants. 3,4 We suggest that all ophthalmic simulatorbased studies should measure participant visual acuity and stereoacuity to ensure reliable results.…”

“…It is, however, possible to do so with the use of an ophthalmic simulator, which we previously used to show other variables that cannot be observed on real patients, such as the effect of distraction, fatigue, and loss of stereopsis on surgical performance. [1][2][3] The aim of this study was to establish the safety of nondominant-hand simulated intraocular surgery.…”
