Whatever Happened to the Contact Lens as a Therapeutic Modality in Keratoconus?

Abstract

Over the past decade the management of keratoconus has changed from the traditional model limited only to rigid gas permeable lenses or penetrating keratoplasty to an array of newer medical and surgical treatment modalities that focus on both prevention of disease progression and improvement of functional visual acuity. New design contact lenses such as keratoconus design rigid gas permeable lenses, soft lenses, hybrid and scleral lenses offer the advantage of better comfort together with improved vision. Fitting of these contemporary contact lenses may postpone or avoid the need for keratoplasty in most of the patients with keratoconus.
