Study Design
A prospective, nonrandomized, comparative cohort case series was carried out at 2 centers (centers A and B) in Australia using a commercially purchased femtosecond laser platform (Catalys Precision Laser; OptiMedica, Sunnyvale, CA) to evaluate the incidence of anterior capsule tear between conventional PCS and FLACS. A clinicopathologic correlation was made between anterior capsule tear rates and anterior capsular integrity by examining ultrastructural integrity of FLACS and PCS capsulotomies
Clinical Outcomes
A total of 1626 consecutive patients undergoing cataract surgery at 2 different centers (centers A and B) were included in this prospective study of the incidence of anterior capsule tears. There were 804 eyes in the FLACS group and 822 eyes in the PCS group. There was no difference in demographics or baseline characteristics between groups (Table 1). The incidence of anterior capsule tears in the FLACS group (n = 15) was significantly higher than that in the PCS group (n = 1) (1.87% vs. 0.12%;
Discussion
This prospective, multicenter study evaluated the safety of FLACS with regard to anterior capsule tears. We found a significantly higher rate of anterior capsule tears in the FLACS group beyond the initial learning curve expected with the technology.9, 10 Current published studies of FLACS technology have emphasized the benefits of FLACS. Benefits include lower phacoemulsification energy resulting in less corneal and macular edema, as well as uniform capsulotomy size and shape.13, 14, 21, 22, 23
