To compare the visual outcomes of phacoemulsification surgery with intraocular lens (IOL) in persons with and without diabetes at end of follow-up.
This was a comparative, cross sectional, observational study with Non-probability, purposive sampling. After approval from "Research Ethical Committee of Isra Post-graduate Institute of Ophthalmology Karachi, 92 patients with cataract in one eye were selected. Patients were divided into two groups. Group A consisted of 48 diabetics and group B consisted of 44 non- diabetics with or without diabetes in the age group ≥ 30 years were included. Patients with small Pupil, Pseudo exfoliation Syndrome, Diabetic Retinopathy, and positive history of Uveitis, Glaucoma, and Macular Degeneration were excluded. Data analysis was performed by SPSS Version 20.0.
Best Corrected Visual Acuity (BCVA) in diabetic patients improved from 0.813 ± 0.181 Log MAR pre operatively to 0.183 ± 0.143 after the period of six months post-operatively. Corresponding results in non-diabetics were 0.66 ± 0.31 and 0.08 ± 0.092 Log Mar (P value = 0.001). If WHO criteria was considered, 87.5% diabetics and 92% non-diabetics achieved normal vision (Log Mar 0 to 0.5; ≥ 6/12,) on the first post-operative day. Remaining 12.5% diabetics and 8% non-diabetics achieved moderate vision (0.6 to 1 Log MAR) on first post-operative day improving to normal vision within a week.
Visual outcomes in diabetics after phacoemulsification with intra ocular lens implant is almost as good as that in non-diabetic patient if the diabetics have no retinopathy and have good glycemic control.
