Intacs

Trade name of an intracorneal implant consisting of two tiny half-ring segments, which are inserted into the cornea to reshape its curvature and correct ametropia. The method is presently used to flatten the cornea by a given amount (the thicker the ring segments the flatter the cornea) in order to correct low myopia. It is an outpatient procedure carried out under local anaesthesia, takes less than half an hour and is reversible. The ring segments are made of clear biocompatible plastic inserted into the stroma and around the optical zone of the cornea.
