How do Intacs work and how might they help me?
Due to the onset and progression of keratoconus, the weakened cornea loses its natural dome-like shape. As a result, the light rays entering the eye are no longer focused properly, impairing one’s ability to see images clearly.
Intacs are specially designed inserts, made of medical plastic, which are surgically placed under the surface of the cornea. Due to their unique patented design, Intacs are able to remodel the architecture of the cornea re-establishing a more natural dome-like shape and improving one’s vision.
The Intacs Corneal Implant Procedure
Prior to any surgical procedure it is common to experience a degree of anticipation and anxiety. It may be comforting to know that the Intacs procedure is far less invasive than a corneal transplant or many other surgical procedures of the eye and the Intacs success rate is high. The surgeons performing the procedure are typically corneal surgeons, having expertise with keratoconus. Each surgeon has also undergone a rigorous training program specific to Intacs for treating patients with keratoconus.
Before the Procedure
Typically, your ophthalmologist, possibly working in tandem with an optometrist will have you undergo a thorough eye examination.
Your examination will include a variety of standard ophthalmic tests for this type of procedure, as well as general medical tests and a review of your specific medical history.
The Intacs Corneal Implant Procedure
Anesthetic drops are used to numb the eye, which is held open throughout the procedure to prevent blinking.
Step 1: A single, small incision is made in the surface of the cornea.
Step 2: The eye is prepared for Intacs placement.
To stabilize your eye and ensure proper alignment of the Intacs inserts, the centering guide is placed on the surface of your eye. During this time, inner layers of the cornea are gently separated in a narrow circular area to allow for Intacs placement.
Step 3: The Intacs inserts are gently placed.
After the second Intacs insert is placed, the small opening in the cornea is closed.
Step 4: The procedure is completed.
The placement of Intacs inserts remodel and reinforce your cornea, eliminating some or all of the irregularities caused by keratoconus in order to provide you with improved vision.
Follow-up visits will be required to monitor the healing process and evaluate the visual benefits of the procedure. Even after a successful procedure, glasses or contacts still may be required to provide you with good vision.
As with any surgical procedure, there are some risks, including infection. Some patients experience visual symptoms including difficulty with night vision, glare, halos, blurry and fluctuating vision.
