Keratoconus is a progressive thinning and cone-shaped deformation of the cornea. In most cases, keratoconus is hereditary and often affects both eyes to varying degrees. In keratoconus, it is assumed that the cornea, or the collagen fibers in the cornea, are not stable enough.
Keratoconus affects approximately 0.25%-0.05% of the population worldwide. Those affected are often allergy sufferers who rub their eyes more often.
The first signs of keratoconus usually occur between the ages of 20 and 30. A gradual visual impairment with a typical increase in astigmatism are the first symptoms. In advanced cases, no improvement in visual acuity can be achieved even with new glasses.
At the latest when these symptoms occur, an ophthalmologist should be clarified, because the earlier keratoconus is identified and treated, the better the long-term success of the treatment.
If keratoconus is detected early, progression can be stopped with minimally invasive treatment.
