Laser subepithelial keratomileusis for treatment of myopia and astigmatism / 医学研究生学报

ABSTRACT

Objective:To evaluate the efficacy of laser subepithelial keratomileusis(LASEK) for the treatment of myopia and astigmatism with a thinner cornea.Methods:Eyes(128) from 67 patients were divided into 2 groups,preoperatively,according to the refractive degree.Group I contained 28 eyes with spherical and cylindrical refraction at-2.5 ~-6.0 DS and 0 ~ 2.0 DC,respectively.Group II contained 100 eyes with spherical and cylindrical refraction at-6.25 ~-14.0 DS and 0 ~-2.0 DC,respectively.Following-up was lasted over half a year and the results were compared.Results:The rates of eyes that achieved vision of 0.5 or better after operation in group Ⅰ and Ⅱ were respectively 76 % and 39 % at one week,89 % and 67 % at 1 month,93 % and 56 % at 6 months.The rates of eyes after operation in group Ⅰ and Ⅱ were respectively 93 % and 56 % for spherical refraction within?1.0 DS,and 96.43% and 76% for cylindrical refraction within?1.0 DC.Conclusion:LASEK was safer and more effective in treating low to moderate myopia with astigmatism than in treating high myopia with astigmatism.
