Details and patient eligibility

About

The purpose of this study is to determine if the device, CATS tonometer prism, measures intraocular pressure significantly differently than the current standard of care tonometer prism (Goldmann) before and after a corneal crosslinking procedure. This difference would be a measurement of the amount of corneal biomechanical changes made due to the cross-linking procedure.

Full description

This clinical trial is a prospective, controlled, study and will be performed at one clinical investigative sites in Tucson Arizona1. The purpose of this study is to determine if the device, CATS tonometer prism, measures intraocular pressure significantly differently than the current standard of care tonometer prism (Goldmann) before and after a corneal crosslinking procedure. This difference would be a measurement of the amount of corneal biomechanical changes made due to the cross-linking procedure.
