目的 评价实时虹膜识别技术在波前像差引导准分子激光原位角膜磨镶术(LASIK)中的价值.方法 随机对照研究.接受实时虹膜识别联合波前引导LASIK手术的近视患者50例(100眼)作为虹膜识别组,接受常规波前引导LASIK手术的近视患者51例(102眼)作为对照组,对两组患者术后1、3、6个月的裸眼视力、屈光度、高阶像差、对比敏感度等进行比较.采用配对t检验、成组t检验、方差分析和卡方检验.结果 术后6个月时,虹膜识别组最佳矫正视力提高1行以上的患者(62眼,62.0％)多于对照组(48眼,47.1％),差异有统计学意义(x2=4.99,P＜0.05)；虹膜识别组的平均散光(-0.19±0.24)D低于对照组(-0.30±0.36)D,差异有统计学意义(t=2.49,P＜0.05).术后6个月,当瞳孔直径为6 mm时,虹膜识别组彗差、三叶草像差均方根值均小于对照组,差异均有统计学意义(t=2.22、3.31,P＜0.05).术后6个月对照组对比敏感度恢复到术前水平,而虹膜识别组略优于术前.结论 实时虹膜识别技术能够提高波前像差引导LASIK手术的视觉质量.

Objective To evaluate the practical value of first-time iris recognition in wavefront aberration-guided laser in situ keratomileusis (LASIK).Methods In a randomized contrast study,101 patients (202 eyes) with myopia were randomly divided into 2 groups:the iris recognition group (50 cases,100 eyes) that agreed to undergo first-time iris recognition combined with wavefront-guided LASIK,and the non-iris recognition group (51 cases,102 eyes) that agreed to undergo conventional wavefront aberration-guided LASIK.Uncorrected visual acuity,refractive error,higher order aberrations and contrast sensitivity were compared between the two groups at 1 month,3 months and 6 months postoperatively.The data were analyzed by SPSS 17.0 statistical software,a t test for the measurement data,and a chi-square test for the enumeration data.Results Six months after the operation,the number of patients who gained more than 1 line of best spectacle-corrected visual acuity (BSCVA) in the iris recognition group (62 eyes,62.0％) was significantly more than that of the non-iris recognition group (48 eyes,47.1％) (x2=4.99,P＜0.05).The degree of astigmatism in the iris recognition group (-0.19±0.24 D) was significantly lower than that in the non-iris recognition group (-0.30±0.36 D) (t=2.49,P＜0.05).At a 6.0 mm pupil size,there was a statistically significant difference in third-order aberration root mean square value between the iris recognition group and non-iris recognition group (t=2.22,3.31,P＜0.05).Six months after the operation,the contrast sensitivity of the non-iris recognition group returned to their preoperative baseline.However,the iris recognition group had slightly better contrast sensitivity than their preoperative levels.Conclusion First-time iris recognition can increase visual quality in wavefront aberration-guided LASIK.
