[Keratoconus lenses: the small correction miracle]

Keratoconus is a non-inflammatory corneal disease associated with a cone-shaped protrusion and progressive corneal thinning. Apart from progression control and stabilizing interventions, correcting the optical error induced by a mostly highly irregular corneal surface is of paramount importance with respect to quality of life and ability to work. This goal can be achieved efficiently by contact lenses with only rare adverse conditions. This article provides a current overview on contact lens fitting in keratoconus and presents own associated results.
