Evaluation of Central Corneal Thickness with Ultrasound Pachymetry After Micro-Coaxial Cataract Surgery

Pur po se: To evaluate the changes in central corneal thickness (CCT) in patients with different values before cataract surgery. Ma te ri al and Met hod: 90 eyes of 70 patients who had undergone uneventful cataract surgery because of senile cataract were included in this prospective study. The CCT was measured by ultrasound pachymetry. The patients were evaluated in 4 groups according to preoperative CCT values (group 1: 450-500 μm, group 2: 501-550μm, group 3: 551-600μm, and group 4: 601-650μm). The CCT was measured preoperatively and at 1st, 2nd, 4th, and 8th weeks postoperatively. The chi-square test and one-way analysis of variance test were used for statistical analysis. Re sults: The increase in CCT was highest in group 1 determined as 71.3 μm. The increase in group 2 was 43.4, 35.1 in group 3, and 16.6 μm in group 4. The increase in CCT was significant in all groups at week 1 ( p<0.05). The increase in group 1 was statistically significant than in groups 3 and 4 (group 1 and group 3, p=0.025; group 1 and group 4, p
