How Corneal Tissue Addition (CTAK) works.
- 01Step 01
Map your cornea in 3-D
Corneal mappingWe capture a detailed three-dimensional map of your cornea to understand the exact shape and steepness of your cone. This map becomes the blueprint the entire procedure is built around.
- 02Step 02
Shape the donor inlay
Femtosecond laserA femtosecond laser sculpts the sterilized donor-tissue inlay to match your individual corneal map precisely - not a one-size-fits-all ring, but tissue shaped for your eye alone.
- 03Step 03
Place it within your cornea
Small channelThe same laser creates a small channel inside your own cornea, and the inlay is gently positioned within it - typically without stitches and while preserving the cornea you already have.
- 04Step 04
Reshape toward a regular cornea
Over the weeks afterOver the following weeks your cornea settles into a smoother, more regular shape, improving how light focuses in your eye and making it far more correctable with glasses or contacts again.

- Step 0160 min

Mapping & candidacy
Detailed corneal topography confirms the shape of your cone and whether CTAK - alone or with cross-linking - is the right fit for your eye.
- Step 02Pre-procedure

Inlay preparation
A femtosecond laser sculpts the sterilized donor-tissue inlay to match your individual corneal map precisely.
- Step 03Outpatient

Procedure
The laser creates a small channel in your cornea and the inlay is gently positioned inside - an outpatient procedure, typically without stitches.
- Step 04Weeks + follow-up

Reshaping & follow-up
Over the following weeks your cornea settles into a more regular shape. We track stability and fine-tune your correction once the eye is stable.

What patients say
Is CTAK a corneal transplant?
No. A transplant replaces your cornea with donor tissue. CTAK adds a small, custom-shaped piece of donor tissue inside your own cornea - preserving the cornea you have.Will I still need glasses or contacts after CTAK?
Often, and that's by design. CTAK's goal is to make your cornea regular enough that glasses or contacts work well and comfortably again. It's about restoring correctable, functional vision - not eliminating correction entirely.Where does the tissue come from? Is it safe?
The inlay is sterilized, treated donor corneal tissue prepared to strict standards. Because it's processed for sterility, the risk of rejection is very low compared to a full transplant.Is it permanent?
The inlay is intended to be long-lasting. Because no corneal tissue is removed, the procedure preserves more future options than a transplant.Can CTAK be combined with cross-linking?
Yes. Many keratoconus patients benefit from cross-linking to stabilize the cornea alongside CTAK to reshape it. Your consultation will determine the right sequence for your eye.Does insurance cover it?
Coverage varies. Our team reviews your specific plan and explains your options clearly before anything moves forward.
