Claim: Laser thermal keratoplasty uses a holmium laser to burn the cornea in order to make the eye temporarily focus better at far distances.
Evidence: The procedure employs a holmium laser to place a ring of concentric laser burns on the cornea between 6 mm and 7 mm in diameter. These burns cause a ring of constriction on the peripheral cornea causing the cornea to steepen making the eye focus better at near.
