INTACS™ are a non-laser approach to vision correction specifically designed to correct mild myopia. They provide an alternative to eyeglasses, contact lenses, and laser refractive procedures which permanently alter the eye by removing tissue from the central optical zone. Intacs™ consist of two clear, ultra-thin, precision-engineered crescents made of polymethylmethacylate or PMMA. This medical polymer has been used safely for almost 50 years for contact lenses and intraocular lenses for cataract surgery. When these crescents are placed in the periphery of the cornea, they are intended to reshape the cornea without removing tissue from the optical zone, which is the critical area for clear vision. This subtle reshaping is designed to make nearsighted corneas flatter, thereby correcting vision.
Intacs™ are recommended for people 21 years or older with stable vision who have mild nearsightedness (-1.00 to –3.00) with less than 1.00 diopter of astigmatism. Patients are given a mild oral sedative and eye drops to numb the eye. A tiny opening is made near the upper edge of the cornea beneath the eyelid. Intacs™ are inserted through that opening so that they rest between the layers of tissue in the cornea. The procedure takes about 15 minutes per eye. The patient should have someone drive them home after the procedure. Typically, vision starts to improve within the first day after surgery. Most people may resume normal activities within two or three days. Although they are intended to remain permanently in place without maintenance, Intacs™ can be easily removed or replaced. In most cases, if they are removed, the refraction returns to pre-operative levels within three months.
