Correlation of Visual Outcome with Postoperative Glycemic Control in Patients with Diabetes Following Cataract Surgery

Purpose: To evaluate visual outcome and analyse the correlation of visual acuity and ocular findings with glycemic control following cataract surgery in diabetic patients. Setting: Department of ophthalmology, Hassan Institute of Medical Sciences, Hassan, Karnataka, India. Design: Prospective Observational Study Methods: Prospective observational study in 54 diabetic patients with cataract. These patients were followed up for 6 months after cataract surgery with evaluation of visual acuity, ocular findings and were correlated with the postoperative glycemic control. Results: 1 week after cataract surgery, 13 patients with normal RBS (<140mg/dl) had visual acuity of 6/6-6/12, four patients with RBS more than 141mg/dl had visual acuity of 6/60- 3/60. Anterior chamber reaction was seen in eight patients with RBS >141mg/dl. At the end of six months, 36 patients with normal RBS had visual acuity of 6/6- 6/12. Remaining patients with RBS >141mg/dl had visual acuity less than 6/12 Conclusion: Good glycemic control after cataract surgery is essential for good postoperative visual outcome in diabetic patient.
