ABSTRACT

aims and objective: To assess and evaluate changes in best corrected visual acuity and the foveal thickness in an uncomplicated cataract surgery in an early post-operative period using optical coherence tomography. Methodology: A prospective clinical study, in which 100 eyes were assessed at baseline, post day-1, week-2 and month -1 using optical coherence tomography after successful SICS with IOL implantation. BCVA and central foveal thickness (CFT) was assessed on every visit. BCVA was recorded on Snellen’s chart, later converted to LOGMAR, while CFT was measured using OCT. results: The mean pre-operative CFT was 234.88± 15.90μm, which increased to 254.20±16.01 μm on day 1, and 246.50±14.93 μm on week 2, which significantly reduced to 237.52±15.23 μm at month 1. Mean pre-operative BCVA was LOGMAR 0.53. BCVA improved significantly to 0.23(6/9p), 0.18(6/9p) and 0.14(6/9) at day 1, week 2 and month 1. The estimated correlation coefficient between pre-operative and post-operative CFT and BCVA were significant (p< 0.05). Conclusion: Following SICS increase in central foveal thickness was seen in early post operative period which returned to baseline by the end of 1 month post operative period. Significant improvement in BCVA can be attributed to decrease in CFT.
