摘　　要：目的评价非接触性眼压计（non—contact tonometry，NCT）经绷带型角膜接触镜测量眼压的可行性和准确性。方法选取2013年11月至2014年6月在温州医科大学眼视光医院需要配戴绷带型角膜接触镜的角膜病、角膜外伤及角膜术后患者42例，共42只患眼。应用NCT分别在患者配戴角膜接触镜前、后测量眼压3次取平均值，比较配戴角膜接触镜前后眼压测值，并进行相关分析以判断角膜接触镜对眼压测量的影响。结果42例患者配戴前的眼压为（13．05±6．16）mmHg，配戴后的眼压为（15．26±6．81）mrnHg，差异有统计学意义（P〈0．05），配戴前后眼压差为（2．21±2．04）mmHg，眼压差最小值-8mmHg，最大值1．4mmHg，95％可信区间为-1．58—2．85mmHg。相关分析显示，配戴前眼压与配戴后眼压差异有统计学意义（r=0．96，P〈0．01）。眼压差与配戴前眼压差异无统计学意义（r=0．17，P=0．28）。结论应用NCT经绷带型角膜接触镜测量眼压是可行的，无需移除接触性角膜镜，可避免不必要角膜再次损伤，但要注意眼压结果可能会高估。Objective To evaluate the feasibility and accuracy of the measurement of intraocular pressure （IOP） by non-contact tonometer （NCT） through bandage contact lenses. Methods IOPs were measured by （NCT） in 42 eyes of 42 patients with and without bandage contact lenses for three times each to get the averages. The values of with and without bandage contact lenses were compared. The correlation of the measurements with and without bandage contact lenses was analyzed. Results The measurement with bandage contact lenses appeared greater than the one without bandage contact lenses （15.26±6.81mmHg vs 13.05±6.16mmHg, P 〈0.05）. The difference of lOPs was 2.21±2.04mmHg, with a maximum of 8mmHg, a minimum of-1.5mmttg, and 95% confidence interval （1.58-2.85mmHg）. The measurements with bandage contact lenses significantly correlated with the measurements without ban- dage contact lenses （r =0.96, P 〈0.01）, while the differences of lOPs did not significantly correlated with the native measurement （r =0.17, P =0.28）. Condusions The measurement of intraocular pres- sure by non-contact tonometer through bandage contact lens is feasible, so it＇s unnecessary to remove lenses frequently before the procedures, lest the corneas will be injured once more. However, it should be noted that IOPs through bandage contact lenses may be overestimated.
