Abstract

Objective In the present study, we reviewed surgically induced astigmatism (SIA) in femtosecond laser-assisted cataract surgery (FLACS) compared with conventional phacoemulsification in patients who have cataract. Background To assess SIA following clear corneal incisions created manually or with the Catalys femtosecond laser. Patients and methods In the present study, patients undergoing FLACS or manual cataract surgery between 2017 and 2019 from a single surgical center in Egypt were considered for inclusion. Postoperative corneal astigmatism values were compared with preoperative astigmatism indices to determine the SIA at 3 months postoperatively using the Alpins vector method. Results Refractive and topographic outcomes from 80 eyes of 40 patients (40 eyes in the manual group and 40 eyes in the FLACS group) were included. There was no significant difference in SIA (manual: 0.96 D and FLACS: 0.72 D) after 3 months postoperatively. Conclusions There was no significant difference in SIA between FLACS and manual cataract surgery after 3 months of surgery.
