Abstract :
Aims: To evaluate changes in macular thickness via-a-vis visual acuity post uncomplicated manual small incision cataract surgery (MSICS) & phacoemulsification surgery
Materials and Methods: Prospective clinical study on 160 patients of uncomplicated immature senile cataract, aged 40-70yrs, patients were randomised into two groups, MSICS & phacoemulsification, by simple 1:1 randomization, who underwent uncomplicated cataract surgery with posterior chamber intraocular lens (PCIOL). Post-operatively, the patients were evaluated for best corrected visual acuity (BCVA) and changes in macular thickness by optical coherence tomography (OCT) at post-op Day 1, 7, 21, 48, and 12 weeks. Paired t-test was used for comparison across follow up.
Results: At 12 weeks post-operative, mean logMAR BCVA was 0.01±0.02 for MSICS group and 0±0.02 for Phacoemulsification group. Macular thickness was not statistically significant (p=0.342) between MSICS group (219.19±17.88µm) and Phacoemlusification group (215.61±16.21µm), at the end of 12 weeks post-operative. Clinically significant macular oedema was not diagnosed in any of the patients at the follow-ups.
Conclusion: Both procedures achieved good post-operative Best Corrected visual acuity without significant differences in BCVA between both the groups at the end of 12 weeks.
