recently introduced surgical implant procedure, known as Intacs or KeraVision rings, corrects mild nearsightedness (myopia) but, unlike other optical implant surgery, it is completely reversible.
The Intac implants can be replaced to correct the changes in vision that occurs normally with age, or they can be removed altogether.
Micro-thin synthetic intercorneal rings are surgically implanted into the cornea to change its´ curvature resulting in a correction or reduction in the myopia.
The procedure is also used in the treatment of Keratoconus, a degenerative condition where the cornea becomes thin and more conical resulting in distorted and multiple vision.
Vision will improve within a few days of the surgery but while the healing process takes place vision may fluctuate for up to three months before settling down.
The results of Intac implants have shown excellent improvement in vision, cannot be felt, require no maintenance and are less visible than contact lenses.
To date, of the few that have had the Intac implants removed, there has been no indication of problems occurring when alternative corrective eye surgery has taken place. If contemplating this procedure you should check with your eye consultant that no problem cases have yet come to light.
