Keratoconus is a progressive eye condition that causes the cornea to thin and bulge into a cone-like shape, leading to blurry, distorted vision and increased sensitivity to light. For many patients, glasses and soft contact lenses may no longer provide clear vision as the condition advances.
Today, exciting advancements in corneal treatment are giving patients more options than ever before. One of the newest innovations in keratoconus care is CTAK® (Corneal Tissue Addition Keratoplasty) by Corneagen®.
What Is CTAK®?
CTAK® is an advanced surgical treatment designed to improve the shape and stability of the cornea in patients with keratoconus and other corneal irregularities.
Unlike traditional corneal transplant procedures, CTAK® uses specially shaped donor corneal tissue segments that are carefully implanted into the cornea to help restore a more natural curvature. The goal is to improve vision quality while preserving as much of the patient’s natural cornea as possible.
This innovative approach may help patients:
- Improve corneal shape
- Reduce irregular astigmatism
- Improve best corrected vision
- Enhance contact lens tolerance
- Delay or potentially avoid a corneal transplant
How Does CTAK® Work?
During the procedure, customized donor corneal tissue segments are placed into precise channels within the cornea. These tissue additions help reshape and strengthen the cornea, improving its overall structure and optical quality.
Because the treatment is customized to each patient’s corneal topography, CTAK® offers a personalized approach to managing keratoconus.
Who May Be a Candidate?
CTAK® may be recommended for patients who:
- Have keratoconus or corneal ectasia
- Experience distorted or unstable vision
- Struggle with contact lens intolerance
- Are seeking alternatives before considering a corneal transplant
- Have irregular corneal shapes affecting vision quality
A comprehensive corneal evaluation is necessary to determine if CTAK® is the right option for you.
CTAK® vs. Other Keratoconus Treatments
There are several treatment options available for keratoconus, and many patients benefit from a combination approach depending on the severity of their condition.
Cross Linking (CXL)
Cross linking helps strengthen the cornea and slow or stop progression of keratoconus.
INTACS®
INTACS® are small corneal inserts designed to flatten and reshape the cornea.
Scleral Lenses
Specialty scleral contact lenses vault over the cornea to provide clearer, more comfortable vision.
CTAK®
CTAK® focuses on restoring corneal shape using donor tissue implants customized to the patient’s cornea.
Why Early Treatment Matters
Keratoconus often progresses over time. Early diagnosis and proper treatment can help preserve vision and improve long-term outcomes. Symptoms may include:
- Blurry or distorted vision
- Frequent prescription changes
- Glare and halos
- Light sensitivity
- Difficulty driving at night
If you notice these symptoms, scheduling a comprehensive eye evaluation is important.
