Advantages of CTAK

What are the advantages of CTAK?

CTAK offers a tailored approach to improve outcomes by addressing the
unique progression of keratoconus in each patient.

  1. Precision and accuracy of a Ziemer Z8 laser-cut custom tissue inlay
  2. Biocompatible materials evaluated to reduce risk of adverse tissue
    response, including potential for extrusion
  3. Clinical study showed no rejection of tissue post-transplant
  4. Custom surgical options detail inlay placement and sizing
  5. Topography flattening and visual acuity improvement
  6. Gamma-irradiation adds rigidity to the inlay and stability for the surgeon
