PURPOSE: To compare capsulotomy outcomes between two femtosecond laser platforms for cataract surgery. METHODS: This retrospective case series included 205 eyes of 162 consecutive patients (75 male and 87 female) aged 68.32 ± 10.27 years (range: 38 to 92 years) who underwent femtosecond laser-assisted cataract surgery (FLACS) using either the LenSx (Alcon Laboratories, Inc., Fort Worth, TX) or the Catalys (Abbott Medical Optics, Abbott Park, IL) laser platform. Intraoperative assessment of the capsulotomy was performed and graded as one of the following four types: complete treatment pattern (type 1), microadhesions (type 2), incomplete treatment pattern (type 3), and complete pattern but not continuous (type 4). RESULTS: Ninety-seven eyes underwent FLACS using the LenSx platform and 108 eyes using the Catalys platform. Ninety-four capsulotomies in the LenSx group were graded as type 1 (96.91%), and three were graded as type 2 (3.09%); all capsulotomies in the Catalys group were graded as type 1 (100%). There was no statistically significant difference between the LenSx and Catalys groups (P >.05). No intraoperative complications (specifically, no posterior capsular extension or vitreous loss) were noticed in any of the eyes included in the study. CONCLUSIONS: The LenSx and Catalys laser platforms demonstrate similar capsulotomy outcomes. The microadhesions that were demonstrated in three cases in the LenSx group did not lead to intraoperative or postoperative complications.
