Observation of artificial lens implantation suture fixation into capsular bag when cataract suspensory ligament rupture without capsular tension ring

Abstract

AIM: To explore the cataract suspensory ligament rupture and artificial lens implantation suture fixation into capsular bag without capsular tension ring(CTR).METHODS: We reviewed 20 cases of 20 cataract suspensory ligament rupture without CTR intraocular lens(IOL)implantation fixation in our department from Jan.2012 to Dec.2016. The needle crossed into ocular ciliary sulcus, in the equator of the eye ball which suspensory ligament rupture from, then the needle crossed out 1.5mm away from the angle of sclera. Sutures fixed on the IOL, then the artificial lens implantation in the pouch, carried out in accordance with the “Z” type suture, or to the beforehand prepared triangle scleral flap. The visual acuity, intraocular pressure, the anterior chamber and the IOL position were measured after operations. RESULTS: All of the postoperative visual acuity improved different level. The postoperative best corrected visual acuity(BCVA)was ≥0.8 in 4 eyes(20%), 0.5-0.6 in 7 eyes(35%), 0.3-0.4 in 8 eyes(40%), 0.1 in 1 eye(5%)because of the glaucoma optic atrophy. There were 12 cases with mild corneal endothelium edema, 4 cases exudation membrane in the pupil area, 2 cases hyphema, all of which recovered after treatment. There were 2 eyes with vitreous prolapse in the pupil, 1 case appeared mild IOL center deviation and no special treatment for the vision did not be involved. Followed up for 6mo, displaced stitches or artificial lens shift did not occur. CONCLUSION: Without CTR, the IOL implantation and suture fixation in capsular bag during cataract surgery is a surgical method for basic-level hospitals.
