Excimer Laser in Situ Keratomileusis for Ultra-high Myopia

Objective: Myopia is a short-sightedness condition and can now be treated by excimer laser keratomileusis to alter and to correct the curvature of corneal surface. This article is to evaluate the accuracy and predictability of laser in situ keratomileusis (LASIK) for high myopia over -10.0 diopters). Methods: 105 eyes of 56 patients with compound myopia ranging -10.00 to-26.00 diopters(D)(mean -13.4 ±3.9D) were treated with LASIK and followed up for 12 months. Results: One months after LASIK, 81 eyes (77.1%) had achieved best-corrected visual acuity. Six months after LASIK, 96 eyes (91.4%) either exceeded or maintained best-corrected visual acuity. Of the 96 eyes, 26 eyes (24.8%) exceeded best-corrected visual acuity; 6 eyes (5.7%) decreased 1 line of visual acuity and 3 eyes (2.9%) 2 lines or more. Conclusions: Laser in situ keratomileusis for myopia over -10,0 diopters shows safety and efficacy. For getting excellent operation results, serious attention should be paid to selection of operation indications and manipulation skill.
