Description
Summary:	To assess the rate of unplanned vitrectomies with femtosecond laser-assisted cataract surgery (FLACS) compared to conventional phacoemulsification at a single, high-volume, multi-surgeon ambulatory surgical center. Retrospective, comparative study of phacoemulsification cases performed in a community-based ambulatory surgical center. A chart review of 2,480 consecutive FLACS procedures performed by 30 surgeons and 36,865 consecutive conventional phacoemulsification surgeries performed by 47 surgeons was conducted. The rate of unplanned vitrectomies was evaluated. In eyes with unplanned vitrectomy, the rates of posterior capsule tear, anterior capsule tear, and zonular dehiscence were analyzed. The unplanned vitrectomy rates between early and late FLACS cases were compared using thresholds of greater than 10, 20, and 50 cases. There were 230 (0.62%) and 16 (0.65%) unplanned vitrectomies in the conventional phacoemulsification and FLACS groups, respectively (P = .89). Of the cases requiring unplanned vitrectomy, posterior capsule tear, anterior capsule tear, and zonular dehiscence rates (conventional phacoemulsification vs FLACS) were 70.9% versus 56.3%, 8.3% versus 12.5%, and 20.9% versus 31.3%, respectively (P = .35). The difference in unplanned vitrectomy rates between early and late cases did not reach statistical significance in any threshold group. FLACS had a rate of unplanned vitrectomy comparable to conventional phacoemulsification. There was no statistically significant difference in unplanned vitrectomy rates between early and late FLACS cases suggesting a short learning curve. [J Refract Surg. 2018;34(9):610-614.].
