传导性角膜成形术后眼内压的变化(英文)

Measurements of intraocular pressure after conductive keratoplasty

目的:探讨传导性角膜成形术(CK)对眼压测量可能影响。方法:在术前和术后第1wk,第4wk,分别用非接触式眼压计(NCT)、Goldmann眼压计(GAT)和Schiotz眼压计测量接受CK治疗的20例36眼的眼压,所得结果采用SPSS11.5软件进行统计分析。结果:和术前比较,CK术后NCT、GAT以及Schiotz眼压计测量值显著降低。眼压变化和年龄、性别、角膜曲率以及拟矫正屈光度无关。结论:CK术后压平式眼压计测量眼压值偏低。

AIM： To investigate the possible impact of conductive keratoplasty（CK）on intraocular pressure（ IOP ）. METHODS： 36 eyes of 20 patients with hyperopia underwent IOP measurement with non-contact tonometer （NCT）, Goldmann applanation tonometer （GAT） and Schiotz tonometer before and after CK. RESULTS： After CK, a significant decrease was observed by NCT, GAT and Schiotz measurements. The change in IOP readings was not correlated with age, sex, keratometric readings, or attempted correction. CONCLUSION： The applanation tonometer atend to underestimate the true IOP after CK.
