摘　　要：Background:To present a surgical technique using a rigid intraocular lens as endocapsular supporting device in manual small incision cataract surgery(MSICS)for treating mild-moderate subluxated cataracts.Methods:In our technique,a single-piece rigid polymethyl methacrylate(PMMA)lens was implanted in the bag following the nucleus removal,with its axis vertical to the zonular dialysis.This endocapsular-implanted IOL stretched the bag and provided sufficient stability and lens centration.This technique was performed in 19 eyes with subluxated cataracts,with zonulysis of≤120 degree and nuclear sclerosis of grade≤3.Mean follow-up time was 9.8 months.Results:All eyes had endocapsular IOL implantation during surgery.Intraoperative extension of the dialysis did not occur in any eye.The IOL was placed in the bag in all but 1 case,in which dislocation of the IOL haptic into the vitreous occurred.Though the IOL was slightly decentered in 3 cases,it kept stable.All patients were asymptomatic.Conclusions:This approach provides a simplified and practical strategy for surgically managing subluxation with mild-moderate zonular loss.
