Intacs Corneal Implants
Intacs corneal inserts or implants are a minimally invasive surgical option used primarily for the treatment of keratoconus.
The approval allows Intacs to be marketed for reduction or elimination of myopia and astigmatism in keratoconus patients where functional vision is no longer obtained with contact lenses or eyeglasses.
The corneal implants are designed for long-term vision correction and very effective at changing the shape of the cornea and flattening the cone caused by keratoconus. But the Intacs procedure cannot halt the progression of keratoconus caused by weakening of the collagen (structural protein) within the corneal tissue.
For treating nearsightedness, Intacs correct vision by flattening the cornea to refocus light rays and improve vision. For keratoconus, Intacs work by flattening the steep part of the cornea or cone to reduce vision distortions.
The procedure takes about 15 minutes and is done on an outpatient basis, but you will need someone to drive you home after surgery. Before surgery, your doctor places anesthetizing drops in your eye and may give you a mild oral sedative.
During the procedure, your surgeon creates a tunnel between layers of the corneal stroma
, outside of the central optical zone.
You won’t feel the ring segments, because they are beneath the cornea’s nerve endings. Other people can’t see them unless they look very closely into your eyes.
