ASTIGMATISM
Based on our previous surgical outcomes, we calculated the sample size. A retrospective analysis of our previous surgical outcomes (with a 3-month follow-up period) revealed that the clinical success rate of the suture method was 63% and that of the incision method was 90%. The sample size was then calculated using the following conditions based on these findings: Fisher’s exact test, α error of 0.05, and statistical power of 0.8. The required number of eyes in each group was 45. The success rate was evaluated using Fisher’s exact test. Wilcoxon’s signed-rank test was used to assess the changes in astigmatism. The Mann–Whitney U test was used to compare the groups in terms of astigmatism changes before and after surgery. A
