Corneal Onlays/Inlays involves placing a coating over your eye to blend with the surface of your eye, and experts believe this may be the most popular type of eye surgery, replacing several others, over the next several years. The coating that is placed over the eye is made from biocompatible materials and alters the way that light enters into the eye, which is what other types of eye laser surgery do.
However, this type is thought to be better than implantable lenses because they are not placed behind the cornea; and it’s also thought to have fewer risks than traditional LASIK and PRK procedures because no tissue is actually removed from the cornea.
A Kamra corneal onlay, which used to be known as the ACI 7000, is a type of corneal inlay that focuses on near vision caused by aging, a condition that’s known as presbyopia. A small incision is first made on the surface of the eye where the inlay is placed. The flap is then placed back in order to hold the inlay in place.
This procedure only takes about fifteen minutes and can be done right in the surgeon’s office. There are no stitches or sutures required, although treatment in the form of eye drops does need to be taken afterward.
The Vue+ is another type of corneal inlay that is used in this type of procedure. This product comes out of Mexico and still has yet to be approved by the FDA, although it has shown very promising results. This inlay is also used in a thin flap, although it’s also often placed in a pocket; and it focuses on treating near or intermediate vision.
One of the major advantages that all cornea inlays and onlays have over other forms of eye laser surgery is that it is reversible.
