Title: Combining pars plana vitrectomy with cataract surgery for proliferative diabetic retinopathy
Abstract: Objective To evaluate the clinical outcomes of pars plana vitrectomy combined with phacoemulsification retaining anterior capsule and posterior chamber intraocular lens(PCIOL) implantation in treatment of patients with concomitant cataract and proliferative diabetic retinopathy(PDR).Methods This retrospective study consisted of 39 eyes of 36 patients with PDR and clinically significant lens opacities.Pars plana vitrectomy was combined with phacoemulsification retaining anterior capsule and PCIOL implantation.Postoperative visual acuity and intra-and post-operative complications were analyzed.Results 36 cases(39 eyes) underwent combined surgery successfully.The median follow up was(13.4±8.6)months(range 2~42 months).The postoperative visual acuity improved in 37 eyes(94.6%),of them,being≥0.05 in 26 eyes(66.7%),≥0.1 in 17 eyes(43.6%),≥0.3 in 7 eyes(17.95);while visual acuity after operation decreased in 2 eyes(5.1%).Diabetic macular abnormalities or optic neuropathy presented to eyes with low visual acuity.Intra-operative complications included retinal injury caused by the piece of the lens nucleus in 3 eyes(7.7%) and anterior capsule tears in 2 eyes(5.1%);post-operative complications included vitreous hemorrhage in 4 eyes(10.3%),corneal edema and transient intraocular pressure rise in 2 eyes(5.1%) respectively,secondary cataract in 3 eves(7.7%),rubeosis iridis and eyeball atrophy in one eye(2.6%) respectively.Conclusions Combined surgery is safe and effective,and so can be widely used.
