Abstract:
PURPOSE: To compare short-term clinical results of femtosecond LASIK with those of epi-LASIK. METHODS: Twenty subjects (40 eyes) underwent femtosecond LASIK and 20 subjects (40 eyes) underwent epi-LASIK for myopia with astigmatism. The results of each surgery were compared with regard to visual acuity, spherical equivalent, safety, efficacy, stability, predictability and high order aberration. RESULTS: Postoperative uncorrected visual acuities were 0.51 +/- 0.11, 0.95 +/- 0.08, and 0.97 +/- 0.08 for epi-LASIK and 0.76 +/- 0.19, 0.97 +/- 0.07, and 0.98 +/- 0.06 for femtosecond LASIK at one week, one month, and two months after surgery, respectively. Femtosecond LASIK showed faster improvement in visual acuity. Postoperative spherical equivalents were -0.83 +/- 0.24, -0.31 +/- 0.19, and -0.27 +/- 0.09 for epi-LASIK and -0.47 +/- 0.21, -0.28 +/- 0.15, and -0.25 +/- 0.12 for femtosecond LASIK. Safety, efficacy, stability, and predictability showed no differences between the two groups. High order aberrations were increased significantly; however, no significant difference between the two groups was found. CONCLUSIONS: Both epi-LASIK and femtosecond LASIK are effective for surgical correction of myopia with fast visual rehabilitation. In addition, epi-LASIK and femtosecond LASIK showed good safeties, efficacies, predictabilities, and stabilities.
