Complication And Learning Curve Of Femtosecond Laser Assisted Cataract Phacoemulsification

Objective:To analyze the incidence of complications associated with femtosecond laser-assisted phacoemulsification and to study the learning curve.Methods:Retrospective analysis.242 patients(403 eyes),who underwent femtosecond laser assisted cataract surgery in Shanxi eye hospital from December 2013 to May 2017,were included in this retrospective study.Used the Alcon LenSx femtosecond laser design completed the anterior capsular circular capsulotomy,lens prepare nucleus chopping and clear corneal incision,then transferred to another operating room completed cataract phacoemulsification combined with intraocular lens implantation,and recorded the complications occurred in femtosecond laser-assisted phacoemulsification.Applied Fisher test compared the incidence of complications in each group.Result:Subconjunctival hemorrhage occurred in 115 eyes(28%);contracted pupil occurred in36 eyes(8.9%);capsulorhexis incomplete or capsulorhexis partial center occurred in 41eyes(10%);intraoperative corneal incision production failed or abnormal position occurred in 44 eyes(11%);the incidence of complications in the above groups showed that the incidence of complications in group A was higher than in group B,group C and group D,moreover the incidence of group B,group C and group D tended to decline gradually stabilized.Conclusion:Femtosecond laser-assisted cataract surgery has some learning curve in the first 100 cases,and the incidence of various surgical complications could significantly be reduced by careful operation and improvement of surgical capability.
