Introduction

Keratoconus is a condition in which the curvature of the cornea is distorted by abnormal thinning of its central and/or paracentral areas. Keratoconic patients are generally fitted with rigid gas-permeable (RGP) lenses to correct the myopic astigmatism that is usually present. Although RGP lenses are usually successful in keratoconic patients, there are significant numbers of patients who experience discomfort and reduced wearing times, often due to a compromised lens fit. This is unavoidable in advanced cases of keratoconus where the cone has steepened, making it difficult to maintain optimal lens fitting characteristics.
