Abstract

目的 比较非接触眼压计(non-contact tonometer,NCT)和Goldmann压平眼压计测量眼压的差异,并分别探讨中央角膜厚度(central corneal thickniss,CCT)对这两种测量方法的影响.方法对108例拟接受PRK或LASIK手术的患者行CCT,NCT和Goldmann压平计眼压测量.结果NCT和Goldmann压平眼压计测得的眼压均值具有显著性差异(F＝89.7044,P＜0.01).CCT与NCT和Goldmann压平眼压计测量值呈正相关,相关系数分别是r=0.4960(t=8.3563,P＜0.001)和r=0.2113(t＝3.1623,P＜0.001).结论 NCT和Goldmann压平眼压计测量眼压值有差异,NCT测量值大于Goldmann压平眼压计,CCT对NCT的影响大于Goldmann压平眼压计。
