What Are Intacs?

Intacs are a newer keratoconus treatment option performed by Dr. Ilan Cohenof 5th Avenue Eye Center. Intacs for keratoconus has demonstrated excellent results.

Intacs keratoconus treatment optionIntacs are corneal ring segment inserts that are also used as an alternative to laser surgery for correcting refractive errors unrelated to keratoconus. These thin, semi-circle implants are made from Plexiglas. They are inserted into the outer edge of the cornea to create a flatter cornea shape. Flattening corneal steepness can improve vision and make the eyes more tolerant to contact lenses.
 

About the Intacs Procedure:

Intacs rings for keratoconusThe Intacs procedure is done on an outpatient basis by Dr. Ilan Cohen and only takes about 15 minutes per eye. Before the procedure, the eye is numbed with anesthetic eye drops. Channels for the inserts are created in the outer edge of the cornea using either a laser or a mechanical spreader. The laser creates fewer complications related to depth of placement and produces better overall results. The Intacs implants are then inserted into the channels to reshape the cornea and opening is closed.
 

What to Expect Afterwards:

Some minor improvement of visual acuity even without contact lenses can be expected, but the main improvement is seen in your ability to tolerate the wearing of contact lenses. Patients who could not wear contact lenses because of keratoconus can return to wearing contact lenses soon after. It’s important to note that this procedure is not intended to completely correct visual acuity in patients with more than mild keratoconus. Some myopia and astigmatism will likely remain even after the Intacs procedure, and some visual correction will probably still be required.
 

Benefits of Intacs for Keratoconus

The Intacs procedure is often used to prevent the need for a corneal transplant in the future. Until Intacs became a commonly accepted keratoconus treatment, corneal transplants were the only treatment option for those who could not tolerate contact lenses.

The Intacs procedure is far less invasive and has a much lower risk of complications than corneal transplant. The main complication from Intacs, although rare, is infection, which can occur with any surgery and can be virtually prevented with prophylactic antibiotics. Intacs are also a better option than corneal transplants because they do not alter the tissue of the eye and can be easily removed (complete reversal) if necessary.
