Abstract

PURPOSE
To evaluate the reproducibility of the flap thickness in LASIK using Moria M2 microkeratome and to examine the safety and the complication rate intraoperatively and postoperatively. METHODS: 92-Ninety-two consecutive eyes of 50 patients that received LASIK using the Moria M2 microkeratome were reviewed. The mean of the predictable corneal flap thickness was compared with the mean of the created corneal flap thickness, and intraoperative and postoperative complication and safety were evaluated. RESULTS: The average corneal flap thicknesses were 140+/-15.16 micrometer with 130 micrometer head and 108.01+/-16.72 micrometer with 110 micrometer head. There was no statistically significant correlation between the predictable corneal flap thickness and the created corneal flap thickness with the 130 micrometer head (p=0.001, one-sample t-test), but there was a stastistically significant correlation with the 110 micrometer head (p=0.573, one-sample t-test). CONCLUSIONS: The M2 Moria microkeratome created a desirable thickness with the 110 micrometer head, and we can expect postoperative stability of the remaining corneal thickness. The complication rate both intraoperatively and postoperatively was very low.
