【摘要】：目的:测量近视眼手术人群的角膜直径，探讨不同性别、眼别角膜直径的差别及角膜直径与等效球镜度数之间的相关性。 方法:对2013年3月—8月来我院近视门诊行准分子激光手术的近视眼126例(252眼),男48例96眼)，女78例(156眼),年龄18～45岁(平均年龄24.23±5.35岁),应用德国Zeiss公司的IOL-Master测量角膜直径[white-to-white（WTW）]距离。对252眼都采用NIDEK RT-2100综合验光仪进行主觉验光,并换算成等效球镜[Spherical equivalent (SE)]，，按照等效球镜度数分成3组：轻度近视(3.00SE≤0.50)、中度近视(6.00SE≤3.00D)、高度近视(SE≤-6.00D)。统计分析此类人群不同性别、眼别之间的角膜直径有无差别及与等效球镜度数之间的相关性。 结果:全部病例角膜直径平均值为(11.52±0.41)mm，其中男性角膜直径(11.60±0.35mm)大于女性(11.43±0.36mm)(P=0.009)；右眼平均角膜直径(11.53±0.40mm)与左眼(11.51±0.42mm)比较无显著统计学差异(P=0.912)；低度、中度和高度近视者的角膜直径的平均值分别为11.59mm、11.48mm、11.45mm,角膜直径与屈光度间呈负相关性（P=0.001），且3组近视患者角膜直径之间存在显著统计学差异(P=0.004)。 结论:近视眼手术人群中男性角膜直径大于女性；近视程度越高，角膜直径越短。
[Abstract]:Aim: to measure the corneal diameter of myopia patients and to explore the relationship between corneal diameter and equivalent spherical lens. Methods: from March 2013 to August, 126 myopia patients (96 eyes in 48 males and 156 eyes in 78 females) underwent excimer laser surgery in our hospital from March 2013 to August. The mean age was 24.23 卤5.35 years old (1845 years old). The corneal diameter was measured by IOL-Master of Zeiss Company in Germany. [White-to-whiteboard WTW] distance. NIDEK RT-2100 comprehensive optometry was used for principal optometry in 252 eyes and converted to equivalent spherical mirror. [Spherical equivalent was divided into 3 groups according to the equivalent spherical degree: mild myopia (3.00 SE 鈮
