Refractive Surgery: Laser Thermal Keratoplasty (LTK)

LTK (laser thermal keratoplasty) is a technique for reshaping corneal tissue to help you see better without glasses or corrective lenses. This procedure uses a holmium laser to gently heat certain areas of the cornea. It shrinks the outer portion of the cornea, making the central cornea steeper.

What to Expect During the Procedure

  • Before treatment, you may be given medication to help you relax.

  • Eyedrops numb your eyes. A device is used to keep your eyes open.

  • Laser treatment lasts a few seconds for each eye.

  • Your vision should start to improve right away. It may take 3-6 months for your vision to become stable.
