INTACS® are microthin polymer ring segments. These inserts are placed under the outer edge of the cornea. INTACS® reshape the cornea from within to allow better focus of light rays on the retina. If adjustments are needed, prescription rings can be replaced or removed if necessary.
Advantages of INTACS® include:
- Delivery of an excellent quality of vision
- Independence on wound healing
- Structural integrity of the eye because tissue is not removed.
The primary disadvantage to using INTACS® is that the ring segments are only FDA-approved for low levels of myopia. The option does not correct astigmatism either.
