An inherited disorder of the eye in which the cornea becomes gradually thinned and conical. The condition affects both eyes and usually develops around puberty, giving rise to increasing myopia and progressive distortion of vision that cannot be fully corrected by glasses. Hard contact lenses improve vision in the early stages, but when vision has seriously deteriorated and contact lenses are no longer helpful it generally becomes necessary to perform a corneal graft.
