INTACS inserts are clear, thin prescription inserts placed in the periphery of the cornea by an ophthalmologist during a brief outpatient procedure. INTACS inserts reshape the curvature of the cornea from within, enhancing the natural shape of your eye to correct mild nearsightedness. Because no tissue is removed (as would be in Lasik or other Eye laser surgery, natural optics are enhanced and the structural integrity of the cornea is maintained.
INTACS inserts cannot be felt, are no more visible than a contact lens and require no maintenance. With INTACS inserts, many people are actually seeing better than 20/20. INTACS inserts are FDA approved and are supported by more than ten years of clinical studies. Another advantage of Intacs is that they are reversible. If for any reason you are unhappy, they can be removed and you eventually return to the same level of myopia.
And, because INTACS inserts are prescription inserts, they can be removed or replaced if you desire or if your vision needs change. In U.S. clinical studies, of the very few people who had their INTACS removed, all were subsequently corrected to 20/20 or better.

Excellent results - in US clinical studies, 97% of patients saw 20/40 or better with INTACS inserts, 74% saw 20/20 or better, and greater than 50% saw 20/16 or better. |

Greater flexibility because INTACS inserts can be removed or replaced with a new prescription should your vision needs change. |
How do INTACS work?
INTACS inserts gently enhance the natural shape of the cornea to allow light rays to focus precisely on the retina, thus producing a clear, sharp image.
To understand how INTACS inserts produce good vision, imagine a tent with a domed top, a shape similar to that of your cornea. If the sides of the tent are extended outward, the top flattens slightly.
INTACS inserts work in a similar fashion. When INTACS inserts are placed in the periphery (sides) of the cornea, outside the vital central optical zone, they gently reshape the centre or "top" of the cornea. This prescription reshaping flattens the centre just enough to allow light rays entering your eyes to focus properly. For most patients, the result is clear vision.
The INTACS procedure
Before the Procedure
Like Laser eye surgery and Lasik, you will need to have a thorough preoperative eye examination to determine if your eyes are healthy and suitable for this procedure. Your examination will include a variety of standard ophthalmic tests, general medical tests and a review of your medical history. You will be have the opportunity to discuss the process with the staff and surgeons at Centre for Sight.
The procedure will be performed on another day (at least 24 hours after your initial consultation).
The procedure itself will take less than 15 minutes per eye, but plan on at least a few hours for your visit.
The procedure for INTACS
Anesthetic drops are used to numb the eye, which is held open throughout the procedure to prevent blinking.
