目的:通过与非接触式眼压计(non-contact tonometer,NCT)的比较,评价Diaton眼压计(DT)在准分子激光原位角膜磨镶术(laser in situkeratomileusis,LASIK)前后眼压测量中的应用价值。方法:在LASIK术前及术后1mo,分别使用NCT和DT测量患者眼压,使用SPSS13.0统计软件对所得结果进行统计学分析。结果:术后1mo时,NCT眼压测量值较术前下降(5.76±2.31)mmHg,DT眼压测量值则无显著差异(t=0.70,P=0.487);NCT与DT读数测量值差值与术中切削量呈正相关,与术后中央角膜厚度呈负相关。结论:Diaton测量眼压不受角膜厚度的影响,因此更适用于LASIK术后患者的眼压测量。

AIM: To evaluate the performance of Diaton tonometer(DT) before and after laser in situ keratomileusis(LASIK) by comparing it with non-contact tonometer (NCT). METHODS:NCT and DT were used to measure the intraocular pressure before and 1 month after LASIK, the results were analyzed with SPSS 13.0. RESULTS: One month postoperatively, NCT readings declined by 5.76±2.31mmHg, DT readings did not differ significantly(t=0.70,P=0.487); the difference between NCT and DT readings had positive correlation with declined corneal thickness, and had negative correlation with the central corneal thickness postoperatively. CONCLUSION: DT readings were not affected by corneal thickness; therefore, Diaton tonometer may be a better choice for the measurement of intraocular pressure after LASIK.
