Myopia the inability to see distant objects clearly.

Nearsightedness is the common term for myopia.

Ophthalmologist is a medical doctor specializing in the diagnosis and medical or surgical treatment of visual disorders and eye disease.

Lacrimal gland - The small structure in each eye which produces tears. It’s above the outer corner of the eye, and lacrimal ducts run from the inner corner to the nose. See also punctum and nasolacrimal duct obstruction.

Laser - Although this is used as a word now, it was originally the acronym for Light Amplification by the Stimulated Emission of Radiation. There are many lasers, all man-made for specific purposes. Laser light has a single wavelength (i.e., color), rather than all colors like everyday white lights. Its waves are directional rather than scattered, and each wave is in step with the next one, which vastly increases the power of a laser light.

DR BOOTHE - EYE LASIK: excimer laser - Laser energy produced by several rare gas- halide mixtures. The term excimer comes from the concept of an energized molecule with two identical components or excited dimer (contracted to one word exci-mer). In PRK the term has for practical purposes become synonomous with the argon-fluoride (ArF) gas version. The wave length of an ArF excimer laser is in the far ultraviolet range at 193 nm.
far sighted - A refractive abnormality of the eye requiring a plus (positive or convex) lens for correction. The term originated because people who are far or distance sighted can see at a distance more clearly than they can see objects which are closer. The medical term is hyperopia or hypermetropia.

Contact Lens, Daily Wear - Contact lenses designed to be worn only during the daytime.

Contact Lens, Disposable - Contact lenses designed to be worn once and then thrown out, as opposed to the kind that’s removed, cleaned, and reinserted. Depending on the eye doctor’s prescription, disposable contact lenses can be worn for one day, or for up to a week.

Contact Lens, Extended Wear - Contact lenses designed to be worn continuously for up to a week, not being removed for sleep.

DR. WILLIAM A. BOOTHE - LASIK DALLAS: Central Ablation Zone - The ablation zone is the area of the eye treated by the laser in LASIK surgery. Around it is the transition zone, where the treated area gradually merges with the original corneal surface that lies outside the ablation zone.

Central Island - An area of the laser-treated part of the cornea which is erroneously not treated, so that its level remains microscopically higher than the surrounding treated surface. The term island describes its appearance. It causes diplopia (double vision).

Macular Edema - Pooling of fluid in and around the macular area of the retina, which causes swelling and impairs vision. It causes blurriness, waviness of straight lines, light sensitivity, and a pink tint to the vision. It usually happens as a result of disease or injury and sometimes after eye surgery. Most people recover from it in a matter of months.

Retinitis Pigmentosa (RP) - Hereditary degeneration of the retina. It usually leads to legal blindness by progressively reducing peripheral vision. There are three main forms:

* dominant, where about half of the family members develop the disease.
* X-linked, for which the females are carriers and males develop the disease in alternating generations.
* recessive, where there is no family history of the disease, but it occurs on occasion.

Rigid Gas-Permeable (RGP) Contact Lenses - Also known as Gas-Permeable (GP) or oxygen-permeable contact lenses. Contact lenses which allows air to pass through them. They are hard, but more flexible than the older-style “hard” contact lenses which were used before 1971. They contain silicone, which is flexible and since it allows oxygen to pass through it, these lenses are more comfortable and healthier for the eye, which needs lots of oxygen.
