AIM: To investigate the clinical efficacy and safety of vitrectomy combined with stage I/II intraocular lens implantation for diabetic retinopathy complicated with cataract.

METHODS: Select 67 case(76 eyes)of diabetic retinopathy complicated with cataract patients in the First Affiliated Hospital of Jiamusi University during March 2015 to April 2017 as retrospective analysis. According to different surgical methods, they were divided into group A(stage I vitrectomy + phacoemulsification + silicone oil filling + intraocular lens implantation, phase II silicone oil extraction)and group B(stage I vitrectomy + lens phacoemulsification + silicone oil filling), stage II silicone oil extraction + intraocular lens implantation). The visual acuity improvement, intraocular pressure and postoperative complications were compared between the two groups.

RESULTS: At 3mo after operation, there was no difference in visual acuity between the two groups(P>0.05). There was no significant change in intraocular pressure between the two groups 3mo before and after surgery(P>0.05). Vitreous hemorrhage(3% vs 5%), choroidal hemorrhage(0% vs 2%), retinal detachment(6% vs 2%), retinal tears(6% vs 10%)There was no significant difference in incidence(P>0.05).

CONCLUSION: There was no significant difference in the efficacy of vitrectomy combined with I/II intraocular lens implantation for diabetic retinopathy complicated with cataract.
