Abstract
Background: Cataract in diabetic patients is a major cause of visual impairment in the world. The aim of cataract surgery in diabetics with raised serum glucose levels is to achieve good postoperative vision and reduced complications. Purpose: The purpose of this study is to observe the intraoperative and postoperative complications and postoperative visual acuity after cataract surgery with intraocular lens implantation in diabetic patients with raised preoperative random blood sugar levels. Materials and method: A single surgeon carried out manual small incision cataract surgery followed by implantation of a posterior chamber intraocular lens. Patients were followed up at day 1, 6 weeks, 6 months and 1 year after surgery. At every visit Best Corrected Visual Acuity, measurement of intraocular pressure, anterior segment examination by slit lamp and dilated fundus examination was done. Result: Maximum number of patients was having excellent visual acuity (85.3%) at 6 weeks follow up and in accordance to WHO recommendations. The most common postoperative complications were early postoperative fibrinous exudates (28.2%), cystoid macular edema (23%), posterior capsular opacification (20.5%). Conclusion: In this study, we observed that over one year period, diabetic patients with raised serum glucose levels who underwent cataract surgery did not show any vision threatening complications. There was no influence of preoperative serum glucose levels on final visual outcome.
Highlights
Diabetes Mellitus (DM) refers to a group of common metabolic disorders that share the phenotype of hyperglycemia
In this study we found that progression of diabetic retinopathy was not correlated with cataract surgery but with the natural course of diabetic vascular disease
The role of perioperative hyperglycemia remains controversial in causation of postoperative endophthalmitis in patients of diabetes mellitus [28, 29], we cannot conclude that higher levels of blood glucose poses a higher incidence of endophthalmitis or poor wound healing in diabetics
Summary
Diabetes Mellitus (DM) refers to a group of common metabolic disorders that share the phenotype of hyperglycemia. More than 285 million people are affected by diabetes mellitus. Cataract is one of the major causes of visual impairment in diabetic patients [4]. Cataract in diabetic patients is a major cause of visual impairment in the world. The aim of cataract surgery in diabetics with raised serum glucose levels is to achieve good postoperative vision and reduced complications. Purpose: The purpose of this study is to observe the intraoperative and postoperative complications and postoperative visual acuity after cataract surgery with intraocular lens implantation in diabetic patients with raised preoperative random blood sugar levels. Conclusion: In this study, we observed that over one year period, diabetic patients with raised serum glucose levels who underwent cataract surgery did not show any vision threatening complications. There was no influence of preoperative serum glucose levels on final visual outcome
