The progression of keratoconus

Keratoconus is a progressive disease, but its progression varies greatly from person to person. It is generally most active in adolescence and young adulthood, then tends to stabilize with age, most often around the thirties or forties.

The disease usually progresses in stages: the cornea gradually deforms and thins, which increases astigmatism and lowers vision. The rate of progression is unpredictable — in some patients it stays subtle, in others, especially the youngest, it can be faster. Over time, in the great majority of cases, keratoconus eventually stabilizes.

• Eye rubbing, the main aggravating factor and the most avoidable.
• An early onset, in adolescence.
• Poorly controlled eye allergies.

Since progression is unpredictable, a regular follow-up with corneal topography makes it possible to detect any progression. It is precisely when keratoconus is progressing that a stabilization treatment can be offered to stop it.

Yes. Today, cross-linking (corneal collagen cross-linking) makes it possible, in the great majority of cases, to stabilize a progressive keratoconus and stop its progression. Combined with stopping eye rubbing and controlling allergies, it has transformed the outlook of the disease.

It is important to remember that keratoconus very rarely causes blindness. With early diagnosis, suitable follow-up and today’s treatments, the vast majority of patients keep good vision.
