Clinical Analysis of Combined Vitrectomy and Phacoemulsification with Intraocular Lens Implantation for Proliferative Diabetic Retinopathy

Purpose: To describe the results and complications of combined pars plana vitrectomy and phacoemulsification with intraocular lens implantation in patients with proliferative diabetic retinopathy, and to analysis the factors to be associated with visual outcome. Methods: Retrospective study was performed on 70 eyes of 58 patients who had undergone combined pars plana vitrecotmy and phacoemulsification with intraocular lens implantation because of proliferative diabetic retinopathy. Preoperative, intraoperative, and postoperative complicated factors to be associated with visual outcome were analyzed. Results: The changes of visual acuity were classified into “improved” 57eyes (81%), “stationary” 7eyes (10%), and “decreased” 6eyes (9%). Posterior capsule rupture during operation was occurred in 2 eyes (2.9%). After cataract, macular edema and neovascular glaucoma were developed in order of incidence of postoperative complications. The factors to be associated with visual outcome were diabetic nephropathy, posterior capsule rupture, macular edema, neovascular glaucoma, and retinal detachment. (P
