誗AIM: To evaluate the long-term effect of laser in situ keratomileusis (LASIK) in the treatment of myopia. 誗 METHODS: A retrospective analysis of the uncorrected visual acuity (UCVA) , refractive diopters, corneal curvature, central corneal thickness and postoperative complications were performed for the people who has accepted the operation for at least 8 years. The patients were divided into three groups according to their degree of preoperative myopia:-1. 00 ~-6. 00D of 92 eyes were in group
more » ... eyes were in group A;-6. 25 ~-10. 00D of 68 eyes in group B; 逸-10. 00D of 27 eyes in group C. 誗RESULTS: More than 8 years after the operation, the UCVA 逸 1. 0 were 73. 9% , 52. 9% and 22. 2% and the refractive diopters were-0. 21依0. 06D,-0. 54依0. 12D,-2. 33依 0. 36D in each group. The residual refractive error within 依1. 00D was 83. 4% and within 依 0. 50D was 59. 4%. There were significant differences between group A and group B / C (P < 0. 05). More than 8 years after LASIK compared with that one year after the operation, the refractive regression more than 1. 00D accounted for 9. 09%. 誗 CONCLUSION: LASIK for the treatment of myopia is safe, effective, predictable and stable. Especially for the low to moderate myopia patients who can obtain more satisfactory treatment effect. 誗KEYWORDS:laser in situ keratomileusis; myopia; long-term effectiveness Citation:Liu XQ, Li J, Yi CJ.
