Diabetes mellitus (DM) affects about 400 million adults globally, a number that is predicted to be doubled by 2035 according to the world health organization (WHO).When cataract surgery is done on diabetic patient the status of retina and retrieval of vision depends on severity of diabetic retinopathy and previous treatment received. In diabetic patients, macular oedema after cataract surgery can be a frequent and complex problem, especially in the patients with pre-existing diabetic retinopathy. The objective of present study is to evaluate the status of diabetic retinopathy after cataract surgery. The hospital based prospective, observational study was carried out. 50 diabetic patients underwent cataract surgery between October 2017 to September 2018. All were studied postoperatively at 1 month and 3 months. This study used OCT to evaluate macular oedema in patients which in turn helped to find out the status of diabetic retinopathy. The present study does not show any progression in diabetic retinopathy in the operated eyes over the short term follow up of 3 months. None of the patients who were having no retinopathy pre-operatively developed retinopathy post operatively.
