A rare case of bilateral keratoconus and granular corneal dystrophy managed with contact lens

Keratoconus (KC) is a bilateral, non-inflammatory, progressive thinning disorder of the cornea that results in high irregular astigmatism, distortion, and poor vision. Granular corneal dystrophy (GCD) is an autosomal dominant stromal dystrophy with onset in childhood that involves the entire cornea. KC associated with GCD is a rare combination that could occur due to abnormal synthetic activity of keratocytes and degeneration of defective basal epithelial cells. This case report shows the management of KC associated with GCD – an uncommon condition.
