Keratoconus is a condition that causes the cornea (the clear window in the front of the eye) to become thin, weak, and slowly sag over time. This change can cause progressive and substantial vision loss which requires eye surgery.
Estimates of the prevalence for keratoconus range from 1 in 500 to 1 in 2000 people. The exact cause of the disease is still be debated but there is strong correlation to genetic, environmental, and hormonal factors. In rare circumstances, it can also occur after LASIK surgery (called post-LASIK ectasia).
INTACS Inserts are two curved, clear plastic segments that are implanted in the perimeter of the cornea to reduce nearsightedness (myopia) in patients with keratoconus. The Inserts are implanted through a small surgical incision on the perimeter of the cornea. The inserts help restore clear vision in keratoconus patients by flattening and repositioning the cornea.
INTACS Inserts are intended for patients with keratoconus who are no longer able to
achieve adequate vision using contact lenses or glasses and for whom corneal transplant
is the only remaining option.
