摘　　要：为评价非接触式眼压计和Ｓｃｈφｔｚ氏眼压计对准分子激光角膜切削术后眼的眼压测量结果和价值，用准分子激光角膜切削术治疗正常眼压的近视患者６２例１２０只眼，术前用非接触式眼压计测量眼压，术后应用０．１％氟甲龙（Ｆｌｕｏｒｏｍｅｔｈｏｌｏｎｅ）点眼四周，术后一月复诊时，分别用非接触式眼压计和Ｓｃｈｉφｔｚ氏眼压计测量眼压。结果：术前眼压非接触式测量平均１６．６２±２．６１ｍｍＨｇ，术后眼压Ｓｃｈｉφｔｚ氏测量平均１８．７６±３．４３ｍｍＨｇ，非接触式测量平均１１．２９±２．８０ｍｍＨｇ，二者有显著差异性（Ｐ＜０．００１），术后异常眼压者Ｓｃｈｉφｔｚ氏检查发现２７例，非接触式眼压计未发现，对异常眼压的诊断有显著差异性（Ｐ＜０．００５）。结论：激光切削是导致术后两种测量方法结果差异的主要原因，使用非接触式眼压计进行准分子激光角膜切削术后眼压的测量并按传统正常值衡量是不准确的，否则会延误类固醇性青光眼的诊断。To evaluate the results and valuation of measuring the intraocular pressure(IOP)after photorefractive keratectomy(PRK)with non contact tonometer(NCT)and Schiφ tz tonometer respectively.method:62 myopic patients(120 eyes)with normal IOP were treated by PRK,IOP was examined with NCT before operation,0 1% fluoremethalone was given four times a day in the first month after operation.At the end of the month,the patientsIOP was measured with NCT and Schiφ tz tonometer.RESULTS:Average IOP examined with NCT is 16 62±2 61mmHg before operation and 11 29±2 80mmHg with NCT at the end of the month after operation,18 76±3 46mmHg with Schiφ tz tonometer.The results of two measurements are of statistically significant differences(P<0 001).Hypertension was found in 27 eyes with Schiφ tz tonometer,but no one with NCT.There is statistically significant differences in finding hypertension between NCT and Schiφ tz tonometer too(P<0 005).conclusion:Photoablation depth is the main cause that makes differences.It isnt accurate to examine IOP with NCT and to value results according to traditional standard after PRK,or it will delay the diagnose of corticosteroid glaucoma.
