Introduction:

Keratoconus is a condition of obscure etiology that is characterized by a non-inflammatory thinning and steepening of the central and/or para-central cornea. The condition usually occurs in the second or third decade of life resulting in a moderate to marked decrease in visual acuity secondary to irregular astigmatism and corneal scarring.

Keratoconus most often occurs bilaterally, however there is often asymmetry with one eye affected more than the other and generally the first eye to develop the condition has a more marked progression.

This differential rate of progression may be an important consideration when counseling patients on the progression of the condition. Cases of unilateral keratoconus are rare but can occasionally be seen in clinical practice.

The clinical management of keratoconus varies depending on the severity of the condition and can range from non-surgical options such as glasses and contact lenses to surgical interventions including intra-stromal inlays and penetrating keratoplasty.
