Summary

Soft contact lens wear reduces the amount of oxygen reaching the eye, which may have an influence on corneal sensitivity. The aim of this study is to measure corneal sensitivity with means of liquid jet esthesiometry at baseline and after 6 days of continuous, extended contact lens wear.

Detailed description

Contact lens wear may have an influence on corneal sensitivity, by three mechanisms: hypoxic, mechanical and inflammatory. Extended silicone hydrogel contact lens wear increases the risk of infections. A change in corneal sensitivity may be considered as an indicator for change in corneal physiology. It is there the aim of this study is to measure corneal sensitivity with means of liquid jet esthesiometry at baseline and after 6 days of continuous, extended contact lens wear.
