title: Contact lens correction of visual loss in keratoconus.
abstract: Visual acuity and contrast threshold functions of 5 bilateral keratoconic patients were measured following spectacle correction and rigid contact lens correction. Visual function was improved by contact lens correction, but some contrast at attenuation remained. This residual loss could not always be related to routine visual acuity findings.
