目的:比较优化的非球面切削准分子激光原位角膜磨镶术(optimized aspheric transition zone,OATz-LASIK)与传统LASIK治疗近视的效果。方法:前瞻性对照研究接受OATz-LASIK治疗近视患者44例(88眼)和同期接受传统切削模式的LASIK手术患者50例(92眼)两组疗效,包括视力、残留屈光度、对比敏感度和眩光敏感度、角膜非球面Q值。结果:术后两组屈光度无显著差异(P>0.05),3mo后OATz-LASIK组视力、对比敏感度和眩光敏感度、显著高于传统组(P<0.05),Q值增加量显著低于传统组(P<0.05)。结论:OATz-LASIK手术安全可靠,术后视觉效果优于传统LASIK。
Objective: To compare the effects of optimized aspheric transition zone (OATz-LASIK) with conventional LASIK in the treatment of myopia. METHODS: Forty-four eyes (88 eyes) with OATz-LASIK and 50 eyes (92 eyes) with LASIK who had undergone conventional cutting were enrolled in this prospective controlled study, including visual acuity, residual refraction, contrast sensitivity and glare Sensitivity, corneal aspheric Q value. Results: After 3 months, the visual acuity, contrast sensitivity and glare sensitivity of OATz-LASIK group were significantly higher than those of the traditional group (P <0.05), and the Q value increased significantly Traditional group (P <0.05). Conclusion: OATz-LASIK operation is safe and reliable, and the postoperative visual effect is better than the traditional LASIK.
