Keratoconus · Surgery in Fez, Morocco
Keratoconus
A progressive cone-shaped deformation of the cornea. When detected early and slowed in time with cross-linking, it stabilizes and vision can be corrected — in Fez, Morocco, by Dr Hassan Oulehri.
Keratoconus often begins in adolescence or young adulthood. The cornea, normally well rounded, thins and bulges into a cone, which blurs and distorts vision. The good news: today it can be detected early, its progression slowed, and sight corrected.
What is keratoconus?
Normal corneaKeratoconus
The cornea — the transparent window at the front of the eye — loses its strength and gradually bulges forward. This deformation creates myopia and astigmatism that are irregular and progressive : hence frequent changes of glasses and vision that stays blurred despite correction.
Eye rubbing is the main aggravating factor. The first reflex to protect your cornea: stop rubbing your eyes (and treat itchy allergies).

Specialty contact lenses
Clear vision without surgery.
Frequently asked questions
Can keratoconus cause blindness?
No. It can significantly impair vision if left untreated, but it does not cause blindness. With screening, follow-up and today’s treatments, vision is preserved in the great majority of cases.
Does cross-linking cure keratoconus?
It does not “cure” it, it stabilizes it : it halts progression in the great majority of cases. The earlier it is performed, the more effective it is. See the treatments.
Can you have LASIK with keratoconus?
No, LASIK is contraindicated : it would weaken the cornea further. Other solutions exist (custom-fitted contact lenses, rings, topography-guided PRK combined with cross-linking).
Do I really have to stop rubbing my eyes?
Yes, it is essential: rubbing is the main aggravating factor. If you have allergies or itching, they should be treated so you no longer feel the urge to rub.
Are glasses enough?
Often yes at first. But as the deformation increases, glasses no longer correct well enough: you then move to custom-fitted lenses or treatments.
