Summary

In order to develop an innovative device to study infectious keratitis, we need to illuminate the cornea of patients suffering from an infectious keratitis with red or near-infrared light. Because of technical reasons the shortest possible wavelength (red) presents advantages.

Detailed description

The aim of this preliminary study is to measure the maximal intensity tolerated during illumination with 6 wavelength corresponding : 2 red, 2 far red and 1 near infrared lights in order to determine the shortest wavelength well tolerated by patients, in comparison with the standard blue light illumination.

Conditions

• Keratitis
