For patients with mild-to-moderate keratoconus, as well as younger patients with high levels of corneal astigmatism, Intacs intracorneal ring segments can be used to reshape the cornea, transforming it from a cone or football-shape to a more normal spherical or dome-like shape. This LASIK alternative can help reduce astigmatism, mild amounts of nearsightedness, and improve quality of vision. Further, Intacs can slow progression of keratoconus and reduce the long-term risk of needing a cornea transplant.
With Dr. Ambati in Eugene, the procedure takes about 15 minutes per eye, entailing a corneal channel created by a laser, followed by insertion of the Intacs rings which provide structural support to the cornea. No stitches are required (the incision is sealed with a tissue sealant, like glue) and a bandage contact lens is in place for 2 weeks. Patients can generally return to work the next day. Some patients may wind up with full correction of pre-existing astigmatism and nearsightedness (especially if they are mild); others may still need soft contact lenses. But the best vision with contacts is typically greatly improved and the cornea stabilized. Patients do need drops for 2 to 4 weeks.
