Laser thermal keratoplasty (LTK) utilizes a focused beam to deliver treatment to specific spots on the corneal surface. This method produces a gradient thermal effect and a cone-shaped zone of collagen shrinkage. CK, on the other hand, uses RF energy applied via a hair-thin tip to penetrate the cornea. This affects deeper layers to create uniform “columns” of collagen shrinkage.
