Iris- The iris is the colored portion of the visible eye. It is a muscle that affects the size of the pupil, depending on the amount of light needed to enter the pupil. Ophthalmologist- An opthalmologist is a medical doctor whose specialization is vision. An opthalmologist can diagnose vision concerns, treat vision concerns, manage vision concerns, perform eye surgery, prescribe medicine, and ophthalmologists can perform laser eye surgery.

The eye and vision errors The cornea is a part of the eye that helps focus light to create an image on the retina. It works in much the same way that the lens of a camera focuses light to create an image on film. The bending and focusing of light is also known as refraction. Usually the shape of the cornea and the eye are not perfect and the image on the retina is out-of-focus (blurred) or distorted. These imperfections in the focusing power of the eye are called refractive errors. There are three primary types of refractive errors: myopia, hyperopia and astigmatism. Persons with myopia, or nearsightedness, have more difficulty seeing distant objects as clearly as near objects. Persons with hyperopia, or farsightedness, have more difficulty seeing near objects as clearly as distant objects. Astigmatism is a distortion of the image on the retina caused by irregularities in the cornea or lens of the eye. Combinations of myopia and astigmatism or hyperopia and astigmatism are common. Glasses or contact lenses are designed to compensate for the eye's imperfections. Surgical procedures aimed at improving the focusing power of the eye are called refractive surgery. In LASIK surgery, precise and controlled removal of corneal tissue by a special laser reshapes the cornea changing its focusing power.

How Safe is LASIK Really? Corrective laser eye surgery is extremely safe when performed by qualified doctors. Like any surgical procedure, there can be complications, but the complication rate is extremely low. Results of clinical studies indicate the chances of having a vision-reducing complication from LASIK Eye Surgery are less than 1%. There have been no reported cases of blindness resulting from laser eye treatment in the United States.
