  • corneal transplant in advanced cases

Natural & lifestyle

  • Stop eye rubbing (treat allergy and itch)
  • check teenagers whose prescription changes fast
  • sunglasses for glare

Emerging & experimental

  • Epithelium-on and accelerated cross-linking

Alternative, off-label & anecdotal

Approaches used outside the guidelines, with what their supporters report and what testing has found so far.

  • Antioxidants and omega-3 — keratoconus corneas show oxidative stress; supplements untested in trials early / small studies
  • Eye exercises and 'palming' — cannot change the shape of the cornea anecdotal / traditional
