AIM: To observe the clinical effect of vitrectomy combined with cataract surgery in the treatment of proliferative diabetic retinopathy(PDR).

METHODS: Totally 80 patients(83 eyes)with PDR who underwent treatment in the hospital during the period from February 2013 to February 2017 were selected and divided into the control group and the observation group according to the treatment method. The control group was treated by vitrectomy combined with lensectomy while the observation group was treated by vitrectomy combined with phacoemulsification. The clinical curative effect was compared between the two groups.

RESULTS: After surgery, the visual acuity of the two groups was improved significantly, and the visual acuity of the observation group was better than that of the control group(P<0.05). The incidence rates of iris neovascularization(INV)and capsular opacities in the observation group after surgery were lower than those in the control group(P<0.05).

CONCLUSION: The clinical effect of vitrectomy combined with phacoemulsification is better than that of vitrectomy combined with lensectomy in the treatment of PDR.
