Abstract

Keratomileusis-in-situ was performed on 18 eyes(15 patients) to correct high myopia. Average preoperative spherical equivalent was -19.26 diopter(D) with a range of -13.25 to -30.50D. The mean postoperative myopia was -4.80D(-0.00 to -9.00D), checked at 6 months postoperatively. Preoperative corneal refractive power was +43.63D, while it decreased to +35.41D at 6 months postoperatively Of all the cases, there was no significant complication except the one who had irregular astigmatism caused by the epithelial ingrowth in the interface. Uncorrected vision of all the patients improved markedly, compared to those preoperatively. In conclusion, keratomileusis-in-situ is a feasible technique for correcting high amounts of myopia, though the calculation program might be improved to obtain adequate prediction.
