What is keratoconus? It is a disease of cornea that causes a progressive thinning of cornea and decrease of eye sight due to increase in eye myopia and irregular astigmatism.
Etiology: genetically weak corneas and due to constant rubbing of eyes due to eye allergy
Treatment: Early stages glasses. mild cases are treated with Rigid gas permeable contact lenses or hybrid lenses
Moderately severe cases: requires Collagen cross linkage ( treating the eyes with Riboflavin eye drops and exposing it to UV light) and INTACS ( femtosecong guided insertion of PMMA ring into the cornea) to support the cornea and correct the vision
In stable keratoconus: Toric ICL can be implanted
In advanced keratoconus: DALK (deep anterior lamellar keratoplasty) corneal transplant or PKP complete corneal transplant can be done.
