目的 了解年龄相关性白内障患者术前角膜散光的特征.方法 连续收集2008年7至12月诊断为年龄相关性白内障,并拟行超声乳化白内障吸除术的患者1389例(1389只眼)的术前角膜曲率资料.双眼患者纳入第一手术眼,对患者角膜散光的大小、类型和分布情况进行描述性统计,并分析年龄、眼轴等因素与角膜散光的关系以及双眼角膜散光的对称性.构成比比较用x2检验,两个变量间的相互关系用Spearman相关分析,对称趋势采用一元线性回归分析.结果 患者平均年龄(67.8±12.3)岁(40.0～79.0岁).角膜散光的中位数0.84 D(0.12～4.36 D),角膜散光≥1.00 D的占32.9%(457只眼),其中逆规性散光(ATR)占53.2%(243只眼).随年龄增加,角膜散光有ATR方向漂移的趋势.眼轴与角膜散光量无相关关系(r=0.179,P=0.203).双眼角膜散光量呈对称趋势,并且散光轴呈镜面对称趋势.结论 在年龄相关性白内障患者中,术前角膜散光患病率较高,主要以轻度散光为主;而且角膜散光有双眼对称趋势;眼轴不是角膜散光大小的直接影响因素.

Objective To investigate the characters of corneal astigmatism in cataract surgery candidates. Methods IOLMaster 5.0 was adopted in this study to measure preoperative corneal keratometry. The first suffered eye was taken as the observed eye when both eyes were involved. Descriptive statistics of keratometric cylinder data were analyzed. The mean of corneal astigmatism, distribution of astigmatism and the cumulated distribution were calculated. The relationship between age, axial length and astigmatism was analyzed respectively. The symmetry of binocular astigmatism was also studied. Results Preoperative keratometric data were obtained from 1389 patients (1389 eyes) with age related cataract (mean age 67.75 years, range from 40 to 79 years). The median of astigmatism was 0. 84 D (0. 12 -4. 36 D). The percentage of corneal astigmatism of 1. 0 diopters(D) or higher was 32. 9% (457 eyes), of which 243 eyes (53.2%) were against-the-rule ( ATR ) astigmatism. With aging, the amount of ATR astigmatism was increasing. Axial length was not correlated with the amount of astigmatism( r = 0. 179 ,P =0. 203 ). Corneal astigmatism was mirror symmetry in both eyes of one person. Conclusions Astigmatism,especially mild astigmatism, was common in patients with cataract, which suggests the importance of astigmatism correction. The symmetry of astigmatism should be considered when both eyes need cataract surgery. Axial length is not related to astigmatism, indicating that the measurement and correction of astigmatism are important even in emmetropia eyes.
