摘要
目的:比较分析超声生物显微镜(ultrasound biomicroscopy,UBM)与IOL-Master测量人眼睫状沟直径的差异,为更准确地计算有晶状体眼后房型人工晶状体植入术(phakicposterior chamber intraocular lens,PPCIOL)也称为可植入的接触镜(implantable contact lens,ICL)的直径提供客观依据(以下简称ICL),从而有效减少术后并发症。方法:选取植入ICL术后1mo的高度近视眼患者32例(60眼)和正视对照组人群28例(48眼),分别作为实验组和对照组,对照组要求排除任何眼科手术史。应用UBM分别测量实验组和对照组的睫状沟直径;应用IOL-Master测量实验组和对照组的角膜横径即水平白到白的距离(whitetowhite,W-W),将所得的数据进行统计学分析。结果:植入ICL后1mo患者的UBM测得的睫状沟直径与IOL-Master测得的W-W值比较其差异有统计学意义(t=2.023,1.988;P<0.05);健康人眼的UBM测得的睫状沟直径与IOL-Maste测得的W-W值比较其差异有统计学意义(P<0.05);ICL术后患者与健康眼的UBM测得的睫状沟直径值比较其差异无统计学意义;二者的IOL-Master测得的W-W值比较其差异也无统计学意义。结论:UBM可以作为测量人眼睫状沟直径的工具;应用IOL-Master眼外测得W-W值与UBM测得的睫状沟直径值是有区别的,我们更倾向于应用UBM测得的值;人眼是存在解剖变异的,这些变异会增加ICL植入的危险性。
AIM： To compare the ultrasound biomicroscopy obtaining more accurate distant of S-S and W-W by （UBM） and IOL-Master for diameter of phakic posterior chamber intraocular lens （ PPC）, also called implantable contact lens （ICL）.
METHODS： Thirty-two high myopia cases （60 eyes） treated with ICL were as experimental group, and 28 normal cases （48 eyes ） without any operation as controls. Ciliary sulcus diameter measured by UBM was denoted by S-S, while,IOL-Master was used to measure the corneal diameter/white to white distant and the records were denoted by W-W. The data were analyzed with statistical method.
RESULTS. There was an excellent correlation between UBM and IOL-Master for the S-S and W-W in the patients after ICL operation （t=2.023, 1,988; P〈0.05）. The mean values of the S-S measured by UBM and IOL-Master were, as follows, 15.96±9.6mm and 11.75±6.9mm. The mean differences of between UBM and IOL-Master measurements were 0.30 ± 0.40mm, and they proved no statistically significance （ t= 0. 002, 0,180; P〉 0.05）.
CONCLUSION： UBM can be a good way to measure ciliary sulcus diameter. The values of W-W and S-S measured by IOL-Master have some differences, and we are more likely to choose S-S value. Anatomical variation will increase risk in ICL operation.
