摘　　要：目的　评价修氏眼压计和非接触眼压计 (NCT)在激光原位角膜磨镶术 (LASIK)后的眼压测量结果及其相互比较。方法　随机选择接受LASIK治疗的高度近视患者 16 5例 ,排除青光眼或高眼压症 ,于术前用非接触眼压计测量眼压 ,术后 1年以非接触眼压计和修氏眼压计进行测量。结果　 1)非接触眼压测量术前平均 (13.9± 2 .5 )mmHg ,术后 1年平均为 (7.0± 1.8)mmHg ;平均眼压测量值下降(6 .9± 2 .1)mmHg;2 )术后 1年眼压修氏测量平均为 (14.3± 3.5 )mmHg ,与非接触眼压测量比较 ,二者差异有显著性 (P <0 .0 5 )。 3)非接触眼压测量改变值与预期屈光度矫正值存在统计学的相关性 (r =0 .2 379,0 .0 0 2 >P >0 .0 0 1)。结论　术后NCT测量值与修氏眼压计测量值比较明显偏低 ,二者测量结果存在显著性差异 (P <0 .0 5 )。激光切削是导致手术后非接触眼压计测量结果下降的直接原因 ,其下降值与预期屈光度矫正值存在相关性 ,预期屈光度矫正值越大 ,下降值越大。LASIK术后不能按传统正常值衡量非接触眼压计测量结果 ,否则可能延误类固醇性青光眼的早期诊断。术后NCT测量值与修氏眼压计测量值比较明显偏低 。Objective To evaluate the results of intraocular pressure(IOP) measurements with Schiotz tonometer and Non-contact tonometer(NCT) after LASIK, and compare the two measurements.Methods Chosinghigh myopia patients 156 with LASIK, those who had glaucoma and hypertension were exluded. Before LASIK, IOP was measured by NCT.One year after LASIK, IOP was measured by NCT and Schiotz tonometer Results 1)The mean IOP using NCT was (13.9±2.5)mmHg before LASIK, and (7.0±1.8)mmHg one year later, the mean IOP decreased (6.9±2.1)mmHg;2)The average IOP using Schiotz tonometerwas (14.3±3.5)mmHg one year later, there was significant difference between the measurements using NCT and Schiotz tonometer(P<0.05);3)There was positive correlation between IOPdropping using NCT and the diopter treating(r=0.2378, P<0.01).Conclusions The NCT measurement after LASIK can't be judged by the normal value in tradition, which may delay the steroid glaucoma dignosis after LASIK. The IOP measurements using NCT is lower than using Schiotz tonometer, this is probably bacause of various design principles of the two tonometer.
