CTAK

CTAK or Corneal Tissue Addition for Keratoplasty is a surgical treatment that can be used to treat keratoconus. It improves vision by changing corneal shape and is less invasive than the traditional surgical treatment of a corneal transplant.

CTAK uses a clear tissue inlay, an arc-shaped piece of sterilized, donated corneal tissue, that is customized specifically for the patient’s eye and is positioned to alter the cornea’s shape, resulting in improved vision.

While CTAK is not a cure for keratoconus, the procedure can improve the patient’s quality of life and help minimize the symptoms of keratoconus including:

• Vision distortion
• Blurry vision
• Light sensitivity
• Irritation
• Glare
• Ghosting

Benefits Of CTAK

• Most patients experience vision improvement within a week
• Significant improvement in patients’ Uncorrected and Corrected Visual Acuity
• Appropriate for thin corneas
• No corneal tissue is removed from the eye (unlike a corneal transplant)
• Fully customized for each eye
• Less invasive than a corneal transplant
• Corneal topography (bulging) may improve
