Retrospective study to evaluate the refractive results of laser in-situ keratomileusis (LASIK) using excimer laser performed on myopic eyes; to determine the accuracy, predictability, safety and stability of LASIK as a treatment to correct myopia. LASIK was performed on 475 eyes of 302 consecutive patients with preoperative spherical equivalent refraction (SE) ranging from -0.50 to -27.00 diopters (D). The eyes were assigned to one of three groups: Croup A (SE less than -6.00 D). B (SE -6.00 to -11.99 D), or C (SE-12.00 D or higher). Follow-up lime was up to 6 months. Results: For all groups, follow-up was obtained for 122 eyes at 6 months. The mean preoperative spherical equivalent was -8.45D 4.66 ISD], and the mean preoperative cylinder was -1.10D ± 1.07 [SD] (range: piano to -6.00D). At 6 months, 95.6% of the eyes in Group A, 97.7% in Group B, and 78.1% in Group C were within 2.00 D of intended correction. The mean regression at 6 months was less than 1.00 D in all groups. Complications were observed in 29 eyes (6%) of all groups. Conclusion: LASIK was found to be very effective and predictable in the correction of low and moderate myopia. For high myopia (> -12.00 D), the effectiveness and predictability of LASIK were fairly good. Results after 6 months tend to suggest the stability of postoperative refraction, but long-term follow-up will be required to make further conclusions.
