Can virtual reality simulation help to determine the importance of stereopsis in intraocular surgery

摘要: Aim To establish the effect of acute loss stereopsis on simulated intraocular surgical performance. Methods This study was performed using EYESi ophthalmic simulator. Thirty junior doctors with no previous experience were enrolled and distance visual acuity (Snellen), near stereoacuity (Frisby) recorded. All participants completed a standard introductory programme forceps module to eliminate learning curve. They then undertook four attempts level 4 binocularly another monocularly simulate an stereopsis. Total score, odometer movement, corneal area injured, lens injured total time taken Results Mean age 31 years (SD±9). None had amblyopia, all demonstrating 6/6 or better N6 for near. 35 s arc (SD±18). Average score decreased from 60 while operating 47 (p 2 2.30 mm 3.53 mm Conclusion The importance surgery is difficult in live theatre setting without compromising patient safety. Virtual reality simulators provide safe alternative. demonstrates statistically significant decrease performance potential training applicants.
