Treatment for Keratoconus
Treatment strategies for keratoconus include:
Contact lenses are the most effective form of treatment for most cases of keratoconus. Early stages of the disease with blurred or distorted vision can be corrected with soft contact lenses. Progressing keratoconus can be treated with rigid gas permeable contact lenses. If you cannot tolerate hard contact lenses, your doctor may prescribe piggyback lenses (hard lens on top of a soft one) or hybrid lenses (rigid centre with outer soft ring). Advanced keratoconus and irregular changes in the cornea can be corrected with scleral contact lenses that rest on the white part of your eye (unlike other lenses), and cover the cornea without coming in contact with it.
Collagen Cross Linking
Collagen cross linking is an emerging treatment option for keratoconus. It involves applying vitamin drops to the cornea and exposing it to ultraviolet A (UVA) rays. This therapy prevents further thinning or bulging and strengthens the cornea.
Lamellar transplant can treat scarring or excessive thinning of the cornea. Lamellar transplant involves replacing only a section of the cornea’s tissue with a donor graft tissue instead of the whole cornea. You will have to wear contact lenses for about one year, during recovery. You will regain your full vision several years after the surgery.
Implantable Collamer Lens
Implantable collamer lens is a biocompatible soft lens that can be permanently implanted into your eye. During the procedure, your doctor will inject the collamer lens into your eye through a micro opening. The lens will unfold and you will experience an immediate improvement in the quality of vision.
