Ocular Surface in Patients With Soft Contact Lenses

Centre Hospitalier Universitaire de Saint Etienne524 enrolled

Overview

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.

Time frame: baseline

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.
