Ocular Surface in Patients With Soft Contact Lenses (E2LC)

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.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Patients with soft contact lenses

Data collected from patient records

  • Demographic data: date of birth, sex, city of birth
  • Contact lenses: laboratory, brand, model, wearing time before the exam, opening date of the blister, solution of contact lenses, material, renewal time
  • Refraction
  • Dry eye disease: Ocular Surface Disease Index (OSDI) score
  • LACRYDIAG data: Non-Invasive Break-Up Time (NIBUT), interferometry and tears meniscus height

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
eye surface condition
Time Frame: baseline
presence or not : dry eye, allergies, blepharitis, corneal abscess, corneal ulceration, corneal neovascularization, chronic inflammatory conjunctivitis and others
baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
refraction
Time Frame: baseline
measured with vision tests
baseline
Ocular Surface Disease Index score
Time Frame: baseline

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.

Time Frame: baseline

interferometry
Time Frame: baseline
with LACRYDIAG. Qualitative & quantitative analysis of the lipid layer.
baseline
tears meniscus height
Time Frame: baseline
with LACRYDIAG
