Clinical observation of laser in situ keratomileusis in treatment of 391 patients with myopia

Objective To investigate the clinical effect of laser in situ keratomileusis(LASIK) for treatment of different degree smyopia.Methods According to the diopters(D) of myopia,391 patients were divided into 4 groups: low myopia(-3.00D),moderate myopia(-3.00D～-6.00D),high myopia (-6.00D～-9.00D)and extremely high myopia(-9.25D),follow-up was 1 year postperatively. Results The naked vision ≥1.0 on 1 year after operation in low myopia,moderate myopia and high myopia were 100%,98.6% and 95.7%,respectively,but was 1.0～0.8 in extremely high myopia(90.2%).The vision regression was observed in 6.3% patients with pre-operative higher astigmia(±1.00D) and myopia(±1.00D). Conclusion Using LASIK to treat different myopia is an effective,divinable and safe operation.
