Efficacy of vitreoretinal surgery for the treatment of retinal detachment after laser posterior capsulotomy

Objective To observe the efficacy of vitreoretinal surgery in the treatment of retinal detachment after laser posterior capsulotomy. Methods A retrospective case-control study. A total of 30 eyes of 30 cases with retinal detachment after laser posterior capsulotomy were enrolled and all cases underwent 23 G vitrectomy under non-contact wide angle lens. The follow-up time was 12 months. Results The retina was reattached successfully after once operation in 27 eyes (90.00%). The retina failed to be reattached in 3 eyes. Among them 2 eyes received second and third operations respectively to achieve retinal reattachment. The retinal detachment with severe proliferative vitreoretinopathy (PVR) was untreatable in 1 eye. Finally there were 29 eyes (96.67%) with retinal reattachment. The difference of visual acuity (Log MAR) was significant between before and after operation (F=2.468, P=0.001). The visual acuity was best at 12 months after operation. Conclusion 23 G vitrectomy with non-contact wide angle lens for the treatment of retinal detachment after laser posterior capsulotomy is safe and effective.
