GAT-DCT-Discordance Due to Corneal Properties

Influence of Discordant Intraocular Eye Pressure Readings Taken by Dynamic Contour Tonometry and Goldmann Applanation Tonometry

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

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