Abstract

Objective:

To determine the mean change in central macular thickness after cataract surgery and to compare the mean change in central macular thickness after cataract surgery in non-diabetics and diabetics without diabetic retinopathy

Study design:

Case control

Study settings and duration:

A case control study was carried out at Ophthalmology department, POF hospital, Wah Cantt. Study duration was 6 months (April 2019-September 2019)

Material and methods:

A sample size of 60 patients was calculated by using Open Epi Software. We used non probability consecutive sampling. Patients were divided into two groups; Cases (Diabetic) and controls (non-Diabetic). All patients underwent phacoemulsification and observed after 4 weeks for macular thickness measurement using optical coherence tomography before and after surgery. Data analysis was done with SPSS version 20. Post stratification t test was applied. P value ≤0.05 was considered significant.

Results:

Total 60 patients were included. Mean age of patients was 65.31 ±7. 63SD.There were 35 (58.3%) males and 25 (41.7%) female patients in the study. We found a significant increase in central macular thickness in cases and controls [(223.100±15.86SD vs 227.2667±17.9SD, p=0.000) and (221.200±12.16SD vs 226.289±16.7861SD, p =0.001)] before and after phacoemulsification in cases and controls respectively. However, no significant difference was found between the groups (p=0.486).

Conclusion:

Central macular thickness was increased after uncomplicated phacoemulsification in both diabetics and non-diabetics without retinopathy for up to a follow-up period of 4 weeks but the thickness did not differ between the two groups.
