Keratoconus is an eye disease that usually begins in the teenage years, becoming more active between 20 and 30, and then more dormant from the age of 40. It always displays secondary symptoms such as allergies, short-sightedness, or astigmatism. The Cornea develops into a conical shape leading to a dilution of the central corneal area and reduced vision
There are several ways to treat the condition including glasses, hard gas permeable contact lenses (e.g.,FlexCone); soft contact lenses, (e.g. HydroCone); surgical procedures (e.g. grafting and corneal transplant) and Corneal collagen crosslinking with riboflavin.
As a Keratoconus patient with glasses it is likely 2 or 3 pairs will be needed to cope with fluctuations in vision due to the changing shape of the cone. Hard gas permeable contact lenses will provide good vision but will always have associated ‘foreign body’ comfort issues, possible limited wearing times, as well as not being suitable for certain activities such as sports.
A solution that avoids these problems and can greatly improve quality of life are soft HydroCone contact lenses, lenses specifically designed for all levels of Keratoconus.
