Visual Health: Treat Keratoconus

Reading time : 2 minutes


Most often affecting teenagers, keratoconus is a little-known disease that affects the cornea and causes thinning and bulging of the cornea. Detected through an ophthalmologist's analysis of the corneal topography, there are now several ways to treat keratoconus . And some good advice is always to give.

Warning symptoms


Keratoconus most often occurs between the ages of 10 and 20 years, with a faster progression around the age of eighteen. Thinning of the cornea deforms the vision by making it more blurred and a diagnosis associating myopia and astigmatism can reveal the formation of keratoconus.

It is important to be particularly vigilant for people whose members the same family were affected, those who develop allergies, eczema, asthma or people with trisomy 21.

For those who develop the disease, it is imperative never to rub the eyes to not make it worse.

Treat keratoconus according to the progress of the disease

Firstly, the discomfort caused by the disease should be evaluated before discussing the treatment to be recommended.

In some cases, especially for the most favorable, it is possible to stabilize the keratoconus and improve the distorted vision .


For that, the simple wearing of glasses can be envisaged but contact lenses promise in general to be more effective (they are used for half of the patients) because they allow to Eliminate a good deal of irregularities in the cornea

When surgery is no longer efficient, surgery should be done.

Transplantation as a last resort of keratoconus

There are now several techniques to surgically treat keratoconus.

Firstly, corneal cross linking (or UVA phototherapy) helps to stop the progression of disease due to the action of a UV ray on a cornea soaked with riboflavin

The placement of intracorneal rings is recommended for patients who do not support lenses. This technique has recently evolved and improves the visual acuity of patients in 70% of cases


More rare, toric implants are possible when the astigmatism is stable but too developed to be corrected by lenses.

Finally, corneal transplantation is proposed, in order not to stabilize the disease but to treat it. However, this is the riskiest technique and should be a last resort option …
