Intacs, a newer therapy involving corneal inserts, is a procedure used to help patients with the eye condition Keratoconus find greater comfort in contact lenses.
Intacs can help vision with glasses or contacts and may occasionally improve unaided vision.
The Procedure – In Detail
Prior to surgery, the cornea is thoroughly evaluated for shape, thickness, power, and overall health. The pupil size is examined as well.
Surgery is typically performed in the laser suite. Anesthetic drops are used to numb the eye, which is held open with an instrument to prevent blinking.
A laser (IntraLase™) is used to create channels in the cornea. Using a delicate instrument, the Intacs inserts are placed in the channels. After the second Intacs insert is placed, the small opening in the cornea is closed (usually with one suture).
The healing process is rapid. As with any surgical procedure, there are some risks, including infection and unwanted visual side effects. If there are any issues, Intacs segments can be removed at any time.
The surgery is performed on an outpatient basis so that the patient is able to leave the surgery center the same day. Patients are advised to arrange for someone to drive them to and from surgery.
