Laser Thermal Keratoplasty or LTK is a procedure that involves applying two rings of laser energy to the mid-periphery of the cornea, gently heating the collagen, within. The collagen gradually shrinks, resulting in a steeper cornea. This treatment is used to correct low to moderate levels of farsightedness (hyperopia).
