To assess the safety and efficacy of femtosecond laser-assisted cataract surgery (FLACS) in Japanese eyes.
Retrospective case series.
The clinical records of 529 consecutive eyes of 312 Japanese patients who underwent FLACS from 2013 to 2016 were reviewed. The completion rates of anterior capsulotomy and corneal incisions using the femtosecond laser (LenSx, Alcon) and the number of attempts to achieve secure docking between the cornea and laser system were recorded. The uncorrected and corrected distance visual acuities (VAs) and uncorrected and distance-corrected near VAs 1 week postoperatively were evaluated.
Anterior capsulotomies were completed in 98.7% of eyes. The corneal incisions were incomplete in 8.3%, which included eyes with arcus senilis and neovascularization. The mean corneal endothelial cell reduction rate was 5.5%. Multiple docking attempts were required in 22.9% of eyes, while canthotomy was performed in two eyes. The postoperative VAs were favorable.
FLACS was safe and reliable in Japanese eyes. Further improvements in docking are required to accommodate small corneas and narrow palpebral spaces.
