5 Facts you should know about

Progressive keratoconus

KCN is a progressive corneal ectasia resulting in irregular astigmatism and loss of visual function

Early signs of keratoconus may include asymmetric refractive error, high or progressive astigmatism, or reduced best corrected visual acuity

The onset of keratoconus often occurs in the teenage years or early twenties but can start at any time

Keratoconus can show the following pathologic findings; fragmentation of Bowman’s layer, thinning of stroma and overlying epithelium, folds or breaks in Descemet’s membrane, and variable amounts of diffuse corneal scarring

Left untreated, 1 in 5 patients with progressive keratoconus may require a corneal transplant - more than half of these patients could need multiple transplants within 20 years
