Ocular Surface Clinical Trial
— E2LCOfficial title:
Ocular Surface in Patients With Soft Contact Lenses
Contact lenses modify the structure of the tear film by biophysical and biochemical
interactions. These changes may explain more common dry eye symptoms and may sometimes cause
lens failure or discontinuation.
In recent years, the investigators have various objective non-invasive methods of tear film
evaluation such as the non-invasive break up time, interferometry, and tears meniscus height.
These measurements are performed in clinical practice during consultation by devices such as
LACRYDIAG.
The improvement of lens comfort requires a better knowledge of the ocular surface in patients
with contact lenses. But currently none of these objective parameters have been accurately
described.
Therefore, the investigators would like to build a database to describe the different
parameters of ocular surface in patients with soft contact lenses.

Secondary | Ocular Surface Disease Index score | is a 12-item questionnaire designed to provide a rapid assessment of the symptoms of ocular irritation consistent with dry eye disease and their impact on vision-related functioning. The overall OSDI score defined the ocular surface as normal (0-12 points) or as having mild (13-22 points), moderate (23-32 points), or severe (33-100 points) disease. |
