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. | ||
