Abstract:
Aims & Objectives:
To compare the visual outcome following cataract surgery in diabetics and non-diabetics.
Method:
A comparative study of 58 eyes in the diabetic and 58 eyes in the non-diabetic group that underwent small incision cataract surgery with posterior chamber intraocular lens implantation. Age, sex, surgical technique, follow up, pre- and postoperative best corrected visual acuity (BCVA) and post-op complications were evaluated
Results:
Out of 116 patients, 58 were diabetic and 58 were non diabetics. In this study, in diabetic group 26 (44.8%) were males and 32 (55.2%) were females. Among non-diabetic 19 (32.8%) were males and 39 (67.2%) were females. The mean age group of patients in diabetic group was 56.5±7.4 and 59.6±5.2 in non-diabetic group. In this study all diabetics were on treatment and 58.6% patients had good glycemic control prior to surgery. All patients underwent small incision cataract surgery. Follow up duration was 4 weeks. The mean preoperative best corrected visual acuity in the diabetic group was 1.60±0.81 and in non-diabetic group was 1.62±0.87. The mean post-operative best corrected visual acuity in log MAR units in the diabetic group was 0.39±0.32 and in the non-diabetic group was 0.32±0.27. The difference in pre and post op visual outcome was statistically significant (p=0.001). The difference in pre and post op visual outcome was statistically significant (p=0.001). Post-operative visual acuity of 6/12 or better was achieved in 62.1% eyes in diabetics and 69% among non-diabetics. Post-operative complications included: posterior capsularopacification, corneal edema, anterior chamber reaction striate keratopathy, pigment dispersion, cystoid macular edema and vitreous. The incidence was higher in the diabetic group.
