| Abstract |
|
Photorefractive keratectomy (PRK), Keratomileusis In Situ (KM), Laser Assisted In Situ Keratomileusis (LASIK), and clear lens extraction have been performed for high myopic patients. Among the above surgical procedures KM and LASIK are applied to young patients in general. However, comparison of clinical results of these two procedures was not reported yet in Korea. To evaluate the clinical results of KM (n=16) and LASIK (n=11) for high myopic patients between -15 diopter (D) and -23 diopter (D), spherical equivalent (S.E) and uncorrected visual acuity were studied for more than ten months, retrospectively. The mean S.E. was changed from -17.36 D before operation to -3.70 D ten months after operation in KM, whereas it was from -17.41 D to -0.31 D in LASIK. At ten months after operation, uncorrected visual acuity equal or better than best corrected visual acuity before operation was 43. 8% in KM and 63. 6% in LASIK. This results show that the clinical result of LASIK were superior to that of KM for high myopia. |
