Myth: Hard contact lenses hold the keratoconic cornea in place and stop progression.
Fact: If your contact lens presses on your cornea with keratoconus it will be very uncomfortable and painful and lead to corneal scarring.
The active period of keratoconus between puberty to your mid-thirties cannot be stopped by putting pressure on the cornea. If there is progression cross-linking should be considered. Cross-linking strengthens the cornea by increasing the cross-link bonds in the corneal tissue. Scleral contact lenses can however correct the anatomical and optical irregularities in Keratoconus to give you better vision.
