Clinical observation on the efficacy of preserving anterior lens capsule in lensectomy combined with vitrectomy surgery

Abstract

Objective To observe the efficacy of preserving complete anterior lens capsule in lensectomy combined with vitrectomy. Methods The records of 68 eyes of 68 patients with vitreoretinal disease complicated with opaque lens were analyzed. The conventional three-channel pars plana vitrectomy and lensectomy were performed on all patients.The cental part of posterior capsule, nucleus and cortex of lens were resected completely by cutting head.The complete anterior capsule and peripheral part of the posterior capsule of lens were retained.Vitrectomy and retinal reattachment operations were performed after above operation. Results The patients were followed up for 12 months.The retina reattached in 66 cases of 68 patients (97.06%) .Two cases(2.94%) occurred recurrent retinal detachment, which were reattached after silicone oil tamponade.The posterior chamber IOL implantation were performed at 6 months after vitrectomy and lensectomy surgery. Conclusion Preserving complete anterior lens capsule in lensectomy and vitrectomy surgery is a safe and effective treatment , which can shorten operative time and reduce complication.
