Abstract:
The purpose of this study is to evaluate the changes of central corneal thickness and axial length after laser-assisted in situ keratomileusis (LASIK) surgery for myopia. 101 eyes of 53 patients who underwent laser in-situ keratomileusis (LASIK) were included in this study.Routine examinations were done in all cases. Central corneal thickness, axial length, keratometry, and refractive error were measured preoperatively and on the 6 month post-operatively. Mean preoperative spherical equivalent was -5.52 D (SD, 1.98 D).Preoperative and postoperative mean central corneal thickness was 530.64 micrometer (SD, 27.62 micrometer)and 468.84 micrometer (SD, 33.32 micrometer).Preoperative and postoperative keratometry was 43.69 D (SD, 1.90 D)and 39.12 D (SD, 1.98 D).Preoperative and postoperative average axial length was 25.56 mm (SD, 1.05 mm)and 25.51 mm (SD, 1.08 mm).When postoperative measurements were compared with preoperative measurements, there was a significant decrease in central corneal thickness (t=25.68, p=0.000)and keratometry (t=23.61, p=0.000), but there was no significant difference in axial length (t=1.82, p=0.072). Refractive changes related to axial length measurements changes on the 6 month after LASIK are not important compared with the total refractive corrections of LASIK.
