Abstract

In order to investigate the clinical results of keratomileusis-in-situ for high myopia, the effects of the procedure on 54 patients(61 eyes) who were followed up at least for 3 months were analyzed retrospectively. Mean preoperative spherical equivalent(S.E) was -20.32 diopter(D), while mean postoperative S.E was -3.70 D at 3 months, -4.81 D at 6 months, -5.82 D at 9 months and -6.13 D at 12 months. Postoperative myopic regression was more severe in male than in female patient group(p<0.01). Postoperative cylindrical change was not significant but uncorrected visual acuity was markedly improved. The complications of keratomileusis-in-situ were loss of corneal cap93 eyes), foreign body in stromal interface(1 eyes), epithelial in growth(6 eyes), increased intraocular pressure(5 eyes), and keratitis(2 eyes). Keratomileusis-in-situ, when performed for severe high myopia with Ruiz nomogram, resulted in undercorrection. And progressive myopic regression was observed until 9 months after surgery especially for young male patients
