One hundred eyes with lens opacities requiring cataract extraction were examined preoperatively by laser interferometry. Sixty-eight of these eyes were also clinically evaluated by estimating media clarity with a direct ophthalmoscope. The predicted acuities obtained from these tests were compared to the actual postoperative Snellen acuity achieved. Both tests were found to be useful predictors; correlation coefficients for interferometry and media estimation were .91 and .88, respectively. Each test was less dependable in patients with the densest cataracts, with poorer correlation coefficients reflecting this; interferometry r = .49 and media estimation r = .19. These results confirm that both tests are useful predictors, but their strengths and weaknesses must be understood.
对100只需要进行白内障摘除术的晶状体混浊眼睛进行了术前激光干涉测量检查。其中68只眼睛还通过直接检眼镜评估介质清晰度进行了临床评估。将这些测试获得的预测视力与术后实际的斯内伦视力进行了比较。发现这两种测试都是有用的预测指标;干涉测量法和介质评估法的相关系数分别为0.91和0.88。在白内障最致密的患者中,每种测试的可靠性都较低,较差的相关系数反映了这一点;干涉测量法r = 0.49,介质评估法r = 0.19。这些结果证实这两种测试都是有用的预测指标,但必须了解它们的优缺点。
