|Intacs are the first FDA approved option for correcting mild myopia
(nearsightedness) that does not require a laser. They are
approved for treatment of -1.0 to -3.0 diopters of myopia with no more
than 1 diopter of astigmatism. Patients must be 21 years of age
As shown below, Intacs are two tiny, clear, ultra-thin crescents
which are made of the same material that has been used for contact
lenses and intraocular lenses (for cataract patients). Intacs
reshape the cornea without disturbing the visual axis and they are
usually placed in the eye permanently, but can be removed if
needed. Intacs are made in different thicknesses which determine the amount of flattening of the cornea. This
flattening is what corrects the vision.
The procedure takes about 15 minutes. The patient is
given drops that numb the eye. Then a tiny opening is made on the
edge of the cornea underneath the eyelid.
After the opening is made, two tunnels are created in the periphery of the
cornea. The Intacs are then placed in these tunnels which are
between the layers of tissue in the cornea.
