超声乳化术后眼压变化的影响因素（英文）

目的:探讨行超乳手术患者前房参数的变化及影响眼压变化的因素。方法:本文对82例105眼行白内障手术的非青光眼患者临床资料进行了纵向分析。研究术后3wk内前房参数、白内障分级、人口统计学资料和眼压变化之间的关系。并评估眼压-前房深度(PD)比率与此期间眼压变化之间的关系。结果:纳入的82例患者平均年龄为60. 1±7. 8岁。术前平均IOP为15. 06±3. 36 mmH g;术后1d增加到15. 75±4. 21mmH g (P=0. 20)。在多因素模型中,与术前值比较,术后21±5d平均IOP变化为-1. 715 mmH g(95%CI:-2. 795,-0. 636)。前房深度(ACD)、眼轴长度、年龄、性别和白内障分级与眼压变化无显著相关。PD比率每增加一个单位,平均眼压就增加1. 289 mmH g (95%CI:0. 906,1. 671)。对术前PD值进行校正后,ACD、眼轴长度、颞侧房角与平均IOP无显著相关性。结论:PD比值是影响术后3wk眼压变化的单一重要因素。

A comparison of visual outcomes in three different types of monofocal intraocular lenses

AIMTo compare the visual outcomes (distance and near) in patients opting for three different types of monofocal intraocular lens (IOL) (Matrix Aurium, AcrySof single piece, and AcrySof IQ lens).METHODSThe present study is a cross-sectional analysis of secondary clinical data collected from 153 eyes (52 eyes in Matrix Aurium, 48 in AcrySof single piece, and 53 in AcrySof IQ group) undergoing cataract surgery (2011-2012). We compared near vision, distance vision, distance corrected near vision in these three types of lenses on day 15 (±3) post-surgery.RESULTSAbout 69% of the eyes in the Matrix Aurium group had good uncorrected distance vision post-surgery; the proportion was 48% and 57% in the AcrySof single piece and AcrySof IQ group (P=0.09). The proportion of eyes with good distance corrected near vision were 38%, 33%, and 15% in the Matrix Aurium, AcrySof single piece, and AcrySof IQ groups respectively (P=0.02). Similarly, The proportion with good “both near and distance vision” were 38%, 33%, and 15% in the Matrix Aurium, AcrySof single piece, and AcrySof IQ groups respectively (P=0.02). It was only the Matrix Aurium group which had significantly better both “distance and near vision” compared with the AcrySof IQ group (odds ratio: 5.87, 95% confidence intervals: 1.68 to 20.56).CONCLUSIONMatrix Aurium monofocal lenses may be a good option for those patients who desire to have a good near as well as distance vision post-surgery.

不同年龄段前角膜散光和后角膜散光相关性的横断面研究（英文）

目的:以不同年龄段分组评估前角膜散光(ACA)和后角膜散光(PCA)。同时分析各年龄段ACA、PCA之间散光程度、散光轴的相关性。方法:横断面研究,包括381眼。将临床测得的散光数值转换为向量记法,以分析ACA和PCA。在整体人群和四个不同年龄段(5~19,20~39,40~59,和≥60)中评估ACA和PCA之间散光程度、散光轴的关系。使用随机效应线性回归模型评估ACA、PCA散光程度之间的关系。结果:在5~9岁儿童中,ACA平均散光度最高为3.59D,PCA为0.50D。总体上来说,ACA在1~10.0D,PCA在0~3.5D。在较年轻的分组中(5~19岁),ACA和PCA显著相关(r=0.85,P<0.001)。在60岁以上组中,ACA每增加1D,PCA增加0.04D(95%CI:0.005,0.07;P=0.03),增加程度相比其余组最少。结论:在60岁以上人群中,相比仅仅依靠经验公式,通过ACA数据计算IOL度数,更为谨慎的方法是同时测定后角膜散光度和散光轴。
