What is Laser Vision Correction?
Laser Vision Correction (LVC) is the term used to describe the surgical procedure by which an excimer laser is used to reshape the cornea, reducing or eliminating the requirement for or dependence on glasses or contact lenses for clear vision.
Re-shaping of the cornea is achieved by removing minute amounts of corneal tissue.
Procedures now exist for nearly all forms of refractive errors (the optical term for a requirement for glasses or contact lenses). When correcting Myopia (short-sightedness) the curvature of the cornea is decreased, or made flatter. When correcting Hyperopia (long-sightedness) the curvature of the cornea is increased to make it steeper. When correcting Astigmatism the curvature of the cornea equalised in all directions.
