目的:探讨oculyzer眼前节全景仪引导的准分子激光角膜磨镶术(laserin situ keratomileusis,LASIK)治疗远视及远视散光的临床疗效。方法:采用随机数字表法将患者55例110眼分为试验组和对照组。试验组应用oculyzer眼前节全景仪引导,进行个体化LASIK(25例50眼);对照组进行传统LASIK(30例60眼)。比较两组术后视力变化、屈光度变化、偏中心切削并发症的发生。结果:两组患者术后视力均明显提高,屈光度均有不同程度回退,试验组和对照组比较,试验组术后裸眼视力更好,6mo时屈光度更稳定,有显著统计学意义(P<0.05);试验组术后偏中心切削发生率明显少于对照组,有极显著统计学意义(P<0.01)。结论:Oculyzer眼前节全景仪引导的LASIK手术治疗远视散光的术后疗效更好,术后并发症更少。

AIM:To evaluate the clinical effect of oculyzer-guided laser in situ keratomileusis(LASIK) and conventional LASIK on the correction of hyperopia and hypermetropic astigmatism.METHODS:Totally 55 patients(110 eyes) were randomly divided into two groups.One group of 25 patients(50 eyes) were performed with oculyzer-guided customized LASIK,the other group of 30 patients(60 eyes) with conventional LASIK.Postoperative uncorrected visual acuity(UCVA),refraction and decentered ablation complication were observed.RESULTS:The postoperative visual acuity of the two groups both improved significantly and the postoperative refraction regressed in varying degrees.In oculyzer-guided customized LASIK group,the postoperative UCVA was better and the refraction at 6 months after operation was more reliable.There was statistical difference between the two groups(P<0.05).The incidence rate of postoperative decentered ablation in oculyzer-guided customized LASIK group was obviously less than that in conventional LASIK group and presented significantly statistical difference(P<0.01).CONCLUSION:Oculyzer-guided customized LASIK for hyperopia showed better visual acuity,less postoperative complication and was predictable.
