Clinical Trial Summary

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.

Outcome

Type Measure Description Time frame Safety issue
Primary eye surface condition presence or not : dry eye, allergies, blepharitis, corneal abscess, corneal ulceration, corneal neovascularization, chronic inflammatory conjunctivitis and others baseline
Secondary refraction measured with vision tests baseline
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.
baseline
Secondary non-invasive tear break-up time with LACRYDIAG baseline
Secondary interferometry with LACRYDIAG. Qualitative & quantitative analysis of the lipid layer. baseline
Secondary tears meniscus height with LACRYDIAG baseline
