非球面个体化切削LASIK与传统LASIK术后视觉效果的比较(英文)

Visual outcome after optimized aspheric transition zone laser in situ keratomileusis compared to conventional LASIK

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。

AIM： To compare the visual effects of optimized aspheric transition zone Laser in situ keratomileusis （OAT z -LASIK ） versus conventional Laser in situ keratomileusis （con. LASIK）. METHODS： In a prospective study 44 patients （88 eyes） underwent OAT z -LASIK and 50 patients （92 eyes） received conventional LASIK surgery. Visual acuity, refractions,contrast sensitivity （CS）,glare sensitivity （GS）, and increment of Q-value after surgery were studied. RESULTS： All of operations on 94 cases were successful without severe complication after 3 months＇ follow-up. There was no significant difference in term of postoperative refractions between the two groups （t-test, P〉0.05）. The uncorrected visual acuity （UCVA）, CS, GS, and increment of Q-value of OAT z group were significantly better compared to the tradition group 3 months after the surgery （P〈0.05）. CONCLUSION： OAT z - LASIK is a more effective procedure to improve visual quality compared to conventional LASIK.
