1、可调节式后房型人工晶体植入的临床观察作者;刘新泉，郭鸣华，杨秋菊，陈洁，陈潞，徐芳［摘要］目的探讨可调节式后房型人工晶体植入术后的临床疗效及调节效果。方法将11例（16眼）单纯性白内障用超声乳化摘除并植入1CU可调节后房型人工晶体作为研究组，同时随机选取同期植入SN60AT后房型人工晶体10例（13眼）作为对照组。手术后随访3个月以上，主要观察远视力、最佳矫正远视力；35cm近视力、最佳矫正近视力；前房深度的变化及调节力的测定（分别用主观法和客观法）。结果1CU可调节后房型人工晶体具有很好的组织耐受性，在囊袋中稳定，居中性好。研究组与对照组裸眼远视力分别为±和土，差异有显著性

2、（t二，Pt=,P»o35cm近视力分别为土和土，差异有显著性（t=,Pt二，Pt二-，P»；客观法（D）分别为土和土，差异有非常显著性（t=-,Pt=4,P结论这种可调式后房型人工晶体早期观察的结果具有良好的术后视功能，比普通的人工晶体具有更大的调节范围，但仍需要观察随着手术后的时间延长其屈光状态和调节能力的变异性及稳定性情况。［关键词］超声乳化；晶状体，人工；前房深度；调节力；1CUClinicaleffectsofanaccommodativePC-IOLafterimplantation[Abstract]ObjectiveToevaluatetheclinicale
