Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

IOP is measured with two devices (Dynamic Contour Tonometry (DCT) and Goldmann applanation tonometry (GAT)).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

DCT reading will be compared to a corrected GAT reading by the formula of Elsheikh, Alhasso and Pye.
