Abstract. Purpose:To compare the incidence of laser disruption of posterior capsule in eyes implanted with acrylic intraocular lens(IOL). Method:This retrospective study was made on 7,368 eyes that received cataract surgery with IOL implantation in the past 6 years. Six types of acrylic IOL were used:SA60AT,MA60BM,VA60CB,VA60BB,YA60BB and YA60BBR. Kaplan-Meier survival estimate was used equating Nd:YAG disruption with death. Results:Laser capsulotomy was performed on 398 out of 7,368 eyes(5.4%). The incidence ranged from 1.1% to 9.7% depending on the type of IOL. Rate of survival was significantly higher for SA60AT and MA60BM than other types of IOL except YA60BBR(p<0.001,log-rank test). Conclusion:Incidence of laser capsulotomy was lower in eyes implanted with IOLs with sharp optic edge.
