Thermal keratoplasty is a refractive surgery technique in which heat is applied to the cornea to shrink and reshape it. This procedure is most commonly used to treat hyperopia (farsightedness), by inducing controlled shrinkage in the corneal tissue, which flattens the cornea and improves focus.

The laser energy used during thermal keratoplasty helps to change the curvature of the cornea without the need for traditional cutting. It is a less invasive option for correcting refractive errors, especially for patients with mild to moderate hyperopia.

Thermal keratoplasty offers a safe, effective treatment for certain types of refractive errors and can improve vision and reduce dependence on corrective lenses.
