Larger than standard contact lenses, scleral lenses rest on the white of the eye and form a fluid reservoir in front of the cornea. They correct irregular or fragile corneas that glasses and conventional contact lenses cannot correct.
Who is it for?
Keratoconus or other changes in corneal shape, previously operated or transplanted corneas, irregular astigmatism, severe dry eye, after-effects of burns or ocular surface disease. They often restore clear vision and greater comfort in patients with significant difficulties.
Fitting
Fitting takes several sessions with a trained professional: topography, measurements, lens trials, then checks of the bearing, fluid clarity and comfort. They are custom-made.
Insertion and care
The lens is filled with preservative-free saline before insertion. Thorough cleaning and disinfection with suitable products are essential. Poor hygiene risks corneal infections (see contact lens care).
Follow-up
Regular check-ups are needed, at least annually: corneal condition, fit and lens wear. See also our article scleral lenses and keratoconus.
Frequently asked questions
Are scleral lenses reimbursed?
For certain indications (keratoconus, irregular cornea), they are partially covered under the rules of French health insurance (Assurance maladie). Ask the reception desk.
Are they uncomfortable?
After an adjustment period, they are generally well tolerated.
How long should they be worn each day?
Depending on tolerance and indication, generally during the day; your doctor adjusts this.
