1、Lenstar900与接触性A超测量白内障患者眼轴的对比研宄【摘要】目的探讨Lenstar900与接触性A超测量白内障患者眼轴的差异，评价Lenstar900测量眼轴的准确性。方法150例白内障手术患者，依据测量方式不同分为Lenstar900测量组与接触性A超测量组，各75例。分别应用Lenstar900与接触性A超两种方法同时由同一医师测量每例患者眼轴，且均由同一医师行白内障超声乳化联合人工晶体植入术，将测得的眼轴计算人工晶体度数作为手术植入人工晶体的度数。术后观察患者角膜情况、前房深度、术后视力，并于术后3个月检查患者术眼屈光情况，对比分析两种测

2、量方法有无差异性。结果接触性A超测量组与Lenstar900测量组测量眼轴结果比较差异无统计学意义(P〉0.05)，所有患者顺利完成手术，无并发症，术后部分患者角膜水肿，绝大部分1周内水肿消退，前房深度正常，均较手术前加深，术后视力恢复至0.5〜1.0;术后3个月两组实际屈光范围［(-1.00±0.25)DSVS(-0.50±0.25)DS］及实际与目标屈光绝对差值［(0.46土0.45)DSVS(0.15土0.35)DS］比较差异有统计学意义(P眼轴DOI：10.14163/j.cnki.ll-5547/r.2016.19.015Comparativ
