Visual outcome following cataract surgery in diabetic retinopathy patients

This study was conducted to find out the visual outcomes and factors that affect visual outcomes following cataract surgery in diabetic retinopathy patients. : The study included 200 patients, 100 patients with diabetes but without diabetic retinopathy, and 100 patients with diabetic retinopathy for this study. The duration of diabetics will be equal in two groups. Ophthalmic examination included visual acuity, anterior segment, and fundus examination- stage of retinopathy pre and post-operative, evaluation 12 months postoperatively included visual acuity (VA), retinopathy progression, and macular edema incidence.: Postoperative visual acuity increased by 2 or more lines in patients. Progression of retinopathy occurred in 26.5% of eyes after cataract surgery and in 9.5% of non-operated fellow eyes. The most common complication during surgery was intraoperative miosis accounting for 12%. The most common long-term complication after surgery was cystoid macular edema. The most common complication following surgery was corneal edema (19%) Cataract surgery in diabetic patients results in a good visual outcome. However, duration of type 2 diabetes mellitus plays an important role in progression of cataract. Poor control of diabetes mellitus was associated with an earlier onset of diabetic retinopathy, as well as the progression of previously controlled retinopathy. Uncomplicated cataract surgery seems to exacerbate the progression of DR in patients with worse-controlled diabetes.
