Icare Tonometry Effects on Keratometry Readings, Topography Readings, and Corneal Staining

Icare tonometry effects of keratometry readings, topography, and corneal staining to demonstrate that the Icare tonometer does not alter subsequent evaluation or testing. This would allow IOP testing to be performed by technical staff at any time during the examination process without affecting subsequent tests. A total of fifteen patients at each of four sites will be evaluated using Icare tonometers provided by Icare USA. The investigator will be masked as to which eye will undergo Icare tonometry. Both the study eye and the control eye will undergo pre-tonometry and post-tonometry testing; Keratometry readings, IOL master, Topography via Pentacam, and corneal staining with fluorescein using the Oxford scoring scale.
