Diopter- A diopter is one whole number on a prescription. The number of diopters on your prescription represents how much correction is needed to normalize your vision. The more myopic or hyperopic you are, the higher your prescription will be represented in diopters; or rather the farther away from zero your prescription will be.

PRK or Photorefractive Keratectomy- PRK is a corneal procedure where the superficial cornea is removed to improve vision. PRK is an Alternative to LASIK Eye Surgery.
WILL MY PROCEDURE BE PAINFUL?
Patients experience virtually no discomfort during the LASIK Vision Correction procedure. Eye drop anesthesia is used to numb the eye prior to the procedure, so no injections are necessary. Immediately after treatment, some patients have reported minor discomfort, like having an eyelash or a dry contact lens in their eye.
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.
Dr. Boothe Laser Center:
LASIK is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses. The goal of this Web site is to provide objective information to the public about LASIK surgery. See other sections of this site to learn about what you should know before surgery, what will happen during the surgery, and what you should expect after surgery. There is a glossary of terms and a checklist of issues for you to consider, practices to follow, and questions to ask your doctor before undergoing LASIK surgery.
Nearsightedness- Nearsightedness is another name for Myopia. Nearsighted people typically have difficulty seeing objects at a distance. Nearsightedness can be so severe that people have difficulty seeing objects up close too.
What is LASIK?
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.

Farsightedness- Farsightedness is another name for Hyperopia or Hypermetropia. Many Farsighted patients have difficulty seeing things up close, and often have crisp-acute distance vision.
