Thermal keratoplasty is used to correct hyperopia by putting a ring of 8 or 16 small burns surrounding the pupil, and steepen the cornea with a ring of collagen constriction. It can also be used to treat selected types of astigmatism.
Laser thermal keratoplasty (LTK) is a no-touch thermal keratoplasty performed with a Holmium laser, while conductive keratoplasty (CK) is thermal keratoplasty performed with a high-frequency electric probe. Thermal keratoplasty can also be used to improve presbyopia or reading vision after age 40.
Intra-Stromal corneal rings (Intacs) are approved by FDA for treatment of low degrees of myopia.
Lens implantation inside the eye can also be used to change refractive errors.

Factors affecting surgery
Typically, the cornea is avascular, because it must be transparent to function normally, its cells absorbing oxygen from the tear film. Thus, low oxygen-permeable contact lenses reduce the cornea's oxygen absorption, sometimes resulting in corneal...
