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.
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.
