Your eye usually works like a perfectly focused camera, where the focusing mechanism of the cornea (the clear window at the front of the eye) and lens brings light to a focus on the retina (the camera film at the back of your eye).
Sometimes light may not be focused properly due to problems with the structure of your eye. These include short sightedness, far sightedness and astigmatism. These are collectively known as refractive errors.
The branch of ophthalmology dealing with surgery to correct refractive errors is known as “refractive surgery”.
Laser vision correction is a type of surgery that improves the focusing power of the eye where an excimer laser (cool temperature laser) is used to improve the focusing power of your eye. This is done by using the laser to change the curvature of the cornea (the clear window at the front of your eye).
