Abstract Objective: To explore curative effect after microkeratome excimer laser epithelial keratomileusis (EpiLASIK) and laser in situ keratomileusis (LASIK) for high myopia, and to evaluate the safety and efficacy of EpiLASIK and LASIK. Methods: Used United States VISX StarS4 laser, and Moria flat push type micro corneal epithelial knife making corneal flap was used for EpiLASIK, with 0.02% mitomycin C sponge soaked in. LASIK used Moria rotating type corneal knife making 110 μm corneal flap. The patients was followed up more than 6 months,and compared postoperative symptoms, visual acuity, refraction, and so on. Results: One week postoperative,the proportion of UCVA≥0.8 of EpiLASIK (47.8%) was less than LASIK (95.8%), the difference was statistically significant (χ2=27.056, P= 0.000); no statistically significant differences were found in those of EpiLASIK(95.7%, 97.8%, 97.8%) and LASIK(97.9%, 97.9%, 97.9%) after 1,3,6 months. After 1 week, the diopter difference was statistically significant (t=-7.123,P= 0.000); after 1,3,6 months the diopter difference was not statistically significant. Conclusion: LASIK was still the mainstream of current treatment of myopia. EpiLASIK was an effective and safe procedure for high myopia. Although the recovery of visual acuity was slower than LASIK, it had a wide range of operation indication, its longterm efficacy still remains to be seen.
