INTACS
What are INTACS?
INTACS, is a procedure for reducing a mild degree of myopia and is being studied for reducing both hyperopia and astigmatism. INTAC inserts are an alternative to laser surgery. INTAC inserts are tiny, crescent-shaped prescription material made of plastic polymer. The inserts are implanted in the periphery of the cornea during a surgery process. They are usually not noticeable and require no maintenance like contacts. The effect they have is to flatten the cornea for better focusing and providing crisp vision. INTAC inserts can be removed and replaced if a need for prescription changes. Removal of INTAC inserts causes vision to regress to the condition they were before the insertion of INTACs.
INTACS Process
Pre-operative procedures for this process include extensive examination of each eye to determine if they are suitable. As in all eye surgeries, the eyes are first numbed with anesthetic drops and an eyelid holder is placed to prevent blinking. A small incision is made in the cornea and a centering guide is placed on the surface. Using the centering guide, two micro-sized tunnels are made in the periphery of the cornea and the INTAC inserts are placed. The opening is closed up and antibiotic drops maybe applied. Improvement in vision should be noticed immediately but some people require a few days.
INTAC Candidates
People are best suited for INTAC inserts that have nearsightedness in the range of -1.00 and -3.00 diopters with less than 1.00 diopter of astigmatism, have healthy eyes with no prior problems, at least 21 years old, and have had stable vision for at least a year. There maybe other factors and it is best to contact a qualified eye doctor.
