Phacoemulsification and intraocular lens implanted combined with vitrectomy to treat hyperplasia diabetic retinopathy

Objective To evaluate the outcome of combined phacoemulsification, in-the-bag implantation of posterior chamber intraocular lens( PCIOL) ,and pars plana vitrectomy for patients with retinal disorders resulting from diabetic retinopathy. Methods This retrospectiive study consisted of 66 eyes of 61 patients with proliferative diabetic retinopathy and clinically significant lens opacities ( Among them, Ⅳ PDR 20 eyes, Ⅴ PDR 33 eyes, Ⅵ PDR 13 eyes). Phacoemulsification and intraocular lens implantation was combined with pars plana vitrectomy. Postoperative visual acuity, and complications were analyzed. Results The Postoperative visual acuity improved : Ⅳ PDR 19 eyes (95% ) , Ⅴ PDR 28 eye (84.8% )s,Ⅵ PDR 13 eyes (38.5% ). Diabetic macular abnormalities present to eyes with low visual acuity. Postoperative major complications included; introgenic tetinal hole occurred in 7eyes ( 10. 6% ) ; intraoperative vitreous hemorrhage in 17eyes(25. 8% ) postoperative vitreous hemorrhage in 7eyes( 10. 6% ) ;delayed corneal epithelial healing in 9 eyes( 13. 6% ) ;corneal edema in 8eyes( 12. 1% ). Conclusions This study suggests that the combined operation of Phaco and IOL implantation, PPV is safe and effective for PDR coexisting with cataract. Combined surgery may prevent a second operation for postvitrectomy cataract, allowing earlier visual rehabilitation. Diabetic macular abnormalities is main reason preventing visual acuity raising.
