Corneal Collagen Crosslinking in the Management of Keratoconus

Keratoconus is a bilateral, non-inflammatory corneal ectasia characterised by progressive corneal thinning and bulging, leading to progressive myopia, irregular astigmatism and corneal scarring1. The associated irregular astigmatism and stromal scarring have a significant negative impact on the quality of life of affected patients. A conservative approach in the management of keratoconus involves spectacles and contact lenses. Surgical intervention including implantation of intra-corneal ring segments or corneal transplantation may be necessary when conservative means become intolerable or insufficient for visual needs2. There are still controversies in relation to the diagnosis and management of keratoconus (KCN)3.
