Corneal sensitivity is the most important protective mechanism of the eye. Thus, measuring it at any given time gives important indicators of corneal physiology, especially in the diagnostics of corneal and systemic diseases (e.g. diabetes, herpes simplex and keratitis) and recovery from ocular surgery. Current commercial measurement methods are outdated, non-quantitative and uncomfortable to use, hence left unused. This results in suboptimal, even poor, diagnosis and treatment for patients.~In this study the operating parameters for a state-of-the-art esthesiometer are defined. The operating principle is based on existing rebound technology which is already approved for IOP measurement.
The purpose of this study is to define the operating parameters for a new method to measure corneal sensitivity.
