Paediatric Cross-Linking in Keratoconus: A Clinical Audit

Abstract

Keratoconus is an ectasia in which progressive thinning and cone-shaped distortion of the cornea result in worsening vision through increasing myopia and astigmatism. Age at diagnosis is usually between 15 and 30 years however it has been suggested that keratoconus is often more advanced if first diagnosed in childhood and progresses more quickly. The estimated prevalence of keratoconus is 1.38 per 1000 population (2). Risk factors include family history of keratoconus, eye rubbing and atopic conditions. Patients may experience a reduction in visual acuity and distortion of the visual field. Keratoconus is diagnosed through keratometry, the measurement of the curvature, thickness and steepness of the cornea with computerised corneal topography.
