目的 探讨晶星900 (Lenstar,LS900)测算人工晶状体度数的准确性.方法 临床病例对照研究.对2012年11月至2013年1月在运城市眼科医院就诊的93例(100只眼)拟行白内障超声乳化联合人工晶状体植入术的患者,行晶星900和A超联合手动角膜曲率计两种方法测量眼轴长度和角膜曲率,比较其病例检出率和眼轴长度;术后随诊3个月观察患者屈光状态.结果 晶星900和A超检查法的病例检出率分别为74％ (74/100)和100％ (100/100),两者间差异有统计学意义(P＜0.05).晶星900和A超测得的眼轴长度分别为(23.13±0.81) mm和(23.00±0.77) mm,两者间差异无统计学意义(P＞0.05);晶星900和A超测得的绝对屈光度差值分别为(0.16±0.35)D和(0.36±0.25)D,两者间差异无统计学意义(P＞0.05).结论 晶星900适用于绝大多数白内障患者,适用范围较A超小,但测算的人工晶状体度数较A超稳定,且能提供角膜厚度、前房深度、晶状体厚度、视网膜厚度及瞳孔大小等更多生物信息.

Objective To evaluate the accuracy of intraocular lens power calculation using Lenstar LS 900.Methods The detection rate and axial length of the Lenstar LS 900 and combined A-scan biometry and manual keratometry in 100 eyes of 93 subjects scheduled for cataract surgery was compared.The refractive outcomes were followed-up 3 months after operation.Results The detection rate of Lenstar LS 900 was 74％,which was statistically significant (P ＜0.05) compared with A-scan biometry with 100％.There was no significant difference in axial length between Lenstar LS 900 with 23.13±0.81mm and A-scan biometry with 23.00±0.77mm (P ＞0.05).There was no significant difference in mean absolute refractive error between Lenstar LS 900 with 0.16±0.35D and A-scan biometry with 0.36±0.25D (P ＞0.05).Conclusions Lenstar LS 900 is suitable for most patients with cataract and has smaller using scale,but it is stable in intraocular lens power calculation of Lenstar LS 900.It can provide additional information,such as corneal thickness,anterior chamber depth and so on.
