Laser in situ keratomileusis (LASIK) for the treatment of low, moderate, and high myopia

Abstract

Purpose: To evaluate the efficacy, safety and predictability of LASIK in the treatment of low, moderate and high myopia. Methods: A prespective study of LASIK for low myopia of -0.75 to -6.00 with less than +1 D of astigmatism and for moderate and high myopia of 6.12 to -20 D with astigmatism up to +4.50 D was performed at our institution from March through November, 1996. The Chiron automated corneal shaper was used for the initial flap, and either the Summit or VISX laser was used for the refractive ablation. Preoperative refraction, uncorrected and corrected visual acuity were compared to postoperative refraction, uncorrected and corrected visual acuity. One day and 1 month results were a..
