- 主要终点
- This study aims to examine the agreement among the three devices(GAT, Icare and Corvis ST) and to investigate potential factors that might account for the difference between the IOP values. It is expected to correlate IOP values with various refractive statuses such as emmetropia, hypermetropia and myopia.

简要总结
Comparison and correlation of the efficacy and accuracy of intraocular pressure (IOP) readings taken with Goldmann Applanation Tonometer (GAT), Icare Tonometer, and Corvis ST in subjects having different refractive errors.
Correlate the influence of corneal biomechanism on the values of IOP evaluated by the use of Goldmann Applanation Tonometer (GAT), Icare Tonometer, and Corvis ST in Emmetropia, Hypermetropia and Myopia.
