Effect of femtosecond laser on long term visual outcome in patients with refractive cataract

Abstract

Objective To explore the effect of femtosecond laser on long term visual outcome in patients with refractive cataract. Methods 75 patients (84 eyes) with refractive cataract treated by ultrasound emulsification operation at our hospital from Aug. 2015 to Aug. 2016 were selected and divided into an observation group (42 eyes) and a control group (42 eyes). The control group was given traditional ultrasound emulsification operation and intraocular lens implantation. The observation group was given femtosecond laser before the ultrasound emulsification operation. The clinical data of the patients was analyzed retrospectively. Results All operations were completed successfully. The incidence of complications was lower in the observation group than in the control group [9.5%(4/42) vs. 26.2%(11/42)] (P 0.05). The naked eye near vision and naked eye far vision of the observation group were higher than those of the control group 1 day, 1 week, and 1 month after the operation (all P<0.05). The clinical effect of the observation group was better than that of the control group (P<0.05). Conclusion Femtosecond laser assisted treatment for refractive cataract can effectively improve the patients’ prognosis of visual acuity and has few complications, so its clinical application prospects are bright.
