Abstract: Purpose: To study the effect of cataract surgery on macular thickness in diabetic patients.
Materials and Method: This prospective comparative study enrolled 100 diabetics and 100 non-diabetics undergoing cataract surgery fulfilling inclusion criteria. Complete ocular examination was done for both the groups preoperatively and postoperatively at 1 week, 1month and 3 months including central macular thickness evaluation using optical coherence tomography.
Result: Significant increase in mean central foveal thickness in diabetics and in non-diabetics post 1 month (P<0.01) of surgery was observed. Incidence of development of clinically significant macular edema was 14% in diabetics and 5% in non-diabetics post 1 month of surgery. No progression of diabetic retinopathy post operatively at any follow up visit was observed.
Conclusion: There was a statistically significant increase in macular thickness after cataract surgery in diabetic patients as compared to non-diabetic patients at 1 month, however at 3 month the difference was not significant.
