目的：目的：研究LASIK术后夜间视力不适（NVCs）的术前危险因素。设计：回顾性非比较病例系列研究。参与者：795例（1488只眼）因近视度达-9.75D（D）而接受LASIK手术的患者（从1999年1月1日至12月31日）。方法：进行完整的术前检查。患者使用Nidek EC-5000非波前引导狭缝扫描准分子激光器和Moria LSK One微型角膜刀进行双侧LASIK手术。术后观察患者12个月。主要结果测量：报告的NVCs为每只眼睛的功能视觉舒适度的基础上进行了主观评分。临床上重要的NVC比值比（OR）计算。结果：报告的NVC从25.6%，在1个月后，在12个月后，4.7%，在这个时候，所有患者报告相似的NVC在双眼。术后12个月的风险因素分层显示，初始近视>5 D的NVCs增加2.8倍，光学区小于或等于6.0 mm的NVCs增加2.5倍，术后等效球镜超出正视+/-0.5 D的NVCs增加2.9倍。在术后第一年的OR的logistic回归中，尝试的球镜矫正、患者年龄和术后等效球镜的作用具有重要意义。在使用6个月和12个月数据的逐步logistic回归中，尝试球面矫正和光学区是NVCs最具预测性的因素（P
Purpose: To study the preoperative risk factors for night vision complaints (NVCs) after LASIK in a clinical setting.Design: Retrospective noncomparative case series.Participants: Seven hundred ninety-five patients (1488 eyes) who underwent LASIK for myopia up to -9.75 diopters (D) (from January 1 to December 31, 1999).Setting. Private clinic.Methods: A complete preoperative examination was performed. Patients had bilateral LASIK surgery using the Nidek EC-5000 non-wavefront guided slit-scanning excimer laser and the Moria LSK One microkeratome. Patients were observed postoperatively for 12 months.Main Outcome Measures: The reported NVCs for each eye were rated on a subjective scale based on functional visual comfort. Clinically important NVC odds ratios (ORs) were calculated.Results: Reports of NVCs decreased considerably from 25.6% at 1 month to 4.7% at 12 months postoperatively, at which time all patients reported similar NVCs in both eyes. Stratification of risk factors at 12 months postoperatively showed a 2.8-times increase in NVCs for initial myopia of >5 D, a 2.5-times increase for an optical zone of less than or equal to6.0 mm, and a 2.9-times increase for a postoperative spherical equivalent outside +/-0.5 D of emmetropia. The role of attempted spherical correction, age of the patient, and postoperative spherical equivalent had significant importance in logistic regression of the OR throughout the first postoperative year. In a stepwise logistic regression using 6- and 12-month data, attempted spherical correction and optical zone were the most predictive factors of NVCs (P
