Keratoconus (KC) is a progressive corneal ectasia, characterized by focal corneal thinning, steepening, and loss of biomechanical strength leading to irregular corneal astigmatism and
decreased vision. The condition is bilateral, asymmetric, and progressive. Progression and worsening of the disease are more likely if disease manifestations occur at a younger age.1 Genetic conditions, allergy, and environmental factors (e.g., eye rubbing, allergy, asthma, and eczema) have been suggested to be evident in more severe cases of KC.2
