Pars Plana Vitrectomy Combined With Phacoemulsification Cataract Surgery in Phakic Diabetes Retinopathy Patients

In the combined surgery group, phakic diabetes retinopathy patients over 45 years old without severe lens opacity will receive pars plana vitrectomy combined with phacoemulsification and intraocular lens (IOL) implantation at the same time.

In the control group, phakic diabetes retinopathy patients over 45 years old without severe lens opacity will first receive pars plana vitrectomy and a subsequent phacoemulsification with IOL implantation will be performed at least 6 month after the PPV.
