Title: [Excimer laser in situ keratomileusis for treatment of myopia].
Abstract: To evaluate the effectiveness of excimer laser in situ keratomileusis (LASIK) for treatment of myopia.928 eyes of 678 myopic patients who received LASIK were studied. The patients were divided into 3 groups according to preoperative diopters (-2.00 - -6.00D, -6.10 - -10.00D & -10.10 - -20.00D). The mean follow-up was 12 months (6 - 18 months) and the results were statistically analyzed.12 months after surgery, in the first group the mean residual refraction was -0.24 +/- 0.50D in 86% and 92% of eyes were in the ranges of refraction +/- 0.50D and +/- 1.00D, the uncorrected visual acuities of 0.5 and 1.0 were in 99% and 86% of the eyes respectively. In the second group, the mean residual refraction was -0.47 +/- 0.64D, the refraction of 83% and 90% of eyes was in the ranges of +/- 0.50D and +/- 1.00D, and the uncorrected visual acuities in 95% and 79% of eyes were 0.5 and 1.0 respectively. In the third group, the mean residual refraction was -0.89 +/- 1.02D, the refraction of 36% and 62% of the eyes were in the ranges of +/- 0.50D and +/- 1.00D, and the uncorrected visual acuities in 68% and 45% of the eyes were 0.5 and 1.0 respectively. 47 eyes had been retreated with LASIK. 5 eyes lost two or more lines of the best corrected visual acuity due to irregular astigmatism, decentration and progressive myopic maculopathy.The results indicate that LASIK can treat myopia in the range of -2.00 - -20.00 D effectively without vision threatening complications. Some modification of the surgical techniques and laser nomogram will help to improve predictability and stability of outcome.
