Intac
Intrastromal Corneal Ring Segments or INTACs are the first FDA approved, non-laser, surgical technique for correcting near sightedness.
The INTACs procedure involves inserting a flexible ring beneath the surface of the cornea to elevate the edge of the cornea. This effectively flattens the front of the eye and decreases near sightedness thus giving better distant vision. At present it cannot be used for far sightedness, astigmatism or high degrees of near sightedness. One possible advantage of INTACs is that the procedure is reversible and can be removed returning the eye to its natural state before surgery. This aspect as well as the lack of any surgical effect on the center of the cornea may make this an attractive option for vision correction for eligible patients.
