摘　　要：目的探讨三维眼前段分析仪（OCUlUSpentacam）对后发性白内障晶状体后囊观察的意义。方法通过动物实验确定本仪器测量的准确性，对后发性白内障后囊厚度的变化做动态观测。结果本仪器囊厚度线状断面可视图的建立数据与光镜检查数据进行比较，差异无统计学意义，个体内可信度检验的标准差的差异也无统计学意义；本仪器囊的线状断面厚度与光镜扫描后发障的后囊厚度比较差异无统计学意义。结论采用oculuspentacam对后发障后囊浑浊过程厚度发展的动态观察具有可信、准确、无创、简便的优点，可以作为选择治疗方法的数据依据。Objective To investigate the accuracy of oculus pentacam in measuring posterior cap- sular thickness of after-cataract patients. Methods The study included experimental investigation and clini- cal observation. Thirty three rabbit eyes were made into after-cataract animal model successfully. The posteri- or capsular thicknesses were measured at 10 days, 6 months and 12 months by oeulus pentacam. The eyeballs were removed and posterior capsular thicknesses were detected by immunohistochemistry under light micro- scope at l0 days, 6 months and 12 months. The results of the same time points were compared. In the clini- cal observation, 52 eyes with after-cataract were enrolled and posterior capsular thicknesses were detected by oculus pentacam at 1 week, 1 month, 3 months and 12 months after cataract surgery. Results In animal experiment, the data of linear cross-sectional graph detected by oculus pentacam were compared with the re- sults of light microscope examination and there was no significant difference between them. The linear cross- sectional thicknesses of posterior capsule were not significantly different from the thicknesses tested under light microscope. The difference of individual credibility test was not statistically significant. In clinical ob- servational study, posterior capsular thickness did not increase until 1 year after surgery. Conclusion Pos- terior capsular thickness of after-cataract detected by oculus pentacam is accurate, reliable, non-invasive and easy to operate, which provides objective data for the choice of clinical treatment.
