Laser thermal keratoplasty (LTK)

Introduction

Non-contact laser refractive surgery using a beam of holmium- YAG laser energy to reshape the cornea


Procedure

The procedure employs a holmium laser to place a ring of concentric laser burns on the cornea between 6-7 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. This procedure may regress somewhat over time.
