Laser in Situ Keratomileusis to Treat Low to Moderate Myopia

ABSTRACT

Laser in Situ keratomileusis(LASIK) has advantages over other refractive surgery. In particular, the refractive outcome to correct high myopia is relatively good. However, photorefractive keratectomy(PRK) is more widely used to treat low to moderate myopia than LASIK procedure. This study was a retrospective analysis of the surgical results after LASIK in the low to moderate myopia(-0.75D~-6.00D). Mean spherical equivalent refractive error was -0,12D, six month postoperatively, which was changed from mean spherical equivalent refractive error -5.07D preoperatively. Mean uncorrected visual acuity showed 0.91. None of the patients have lost their best corrected VA. Retreatment with LASIK enhancement for residual myopia was necessary in 6 eyes, because of undercorrection. This results showed that LASIK can be recommend to treat low to moderate myopia.
