Myopic keratomileusis: results with a follow-up over one year

We report one-year follow-up results on 23 eyes in which we performed myopic keratomileusis. The mean refraction changed from -11.09 diopters (D) preoperatively to -3.66 D postoperatively. In all but two cases, keratometry was reduced one year postoperatively. The average corneal thickness decrease was 0.139 mm. In nine eyes, irregular astigmatism severely affected vision. We do not feel that keratometry changes and refractive changes can be statistically related, nor can corneal thickness and postoperative irregular astigmatism. Although myopic keratomileusis is a technically safe treatment, it is not a precise, predictable method for correcting myopia.
