LASIK EYE - DR WILLIAM A. BOOTHE

Radial Keratotomy (RK) - (keh-ruh-TAH-tuh-mee) A surgical treatment for myopia. A myopic eye has a cornea which is too steep, refracting light rays too much, so they land in front of the retina, instead of on it, for clear vision. To make the cornea slightly flatter, tiny incisions are placed around the pupil, angled from the pupil out to the edge of the cornea. The number of incisions and their exact location depends on the degree of myopia.

These are very finely-tuned or subtle lasers. Each pulse removes only 1/4000 of a millimeter of corneal tissue, and to get a better idea of how small that is, think of the width of a human hair: it would take 200 pulses of the excimer laser to cut that hair in half.
It cuts tissue by breaking bonds within collagen molecules. Its wavelength is such that the ultraviolet light is instantly absorbed by the water within the corneal tissue. The cornea has a high water content, and this absorption of the laser light by the corneal surface prevents it from penetrating any further into the eye. This makes it a good tool for precise sculpting of the corneal surface.

DR WILLIAM A. BOOTHE - DALLAS: New York, NY (PRWeb) January 14, 2007 -- It was announced on Monday that the boards of two of the major Lasik companies have agreed to merge: American Medical Optics will acquire Intralase for $808 Million. AMO has been in the eye care field for many years furnishing contact lenses, eye pharmaceuticals, as well as cataract instruments.
AMO was spun off from Allergan in 2002 and quickly entered the Lasik field by buying up Visx, the first and major Lasik company. The manufacturer benefits not only from the sale of the laser but also every time the laser is used on an eye - a royalty fee is paid by the doctors. Visx has about 60% of the Lasik market. Now AMO will have the Intralase system that performs the first step of Lasik. AMO also has marketed a microkeratome with which the first step of Lasik was performed, however the "blade" was the principle cause of complications before the all-laser technique.
About five years ago, Dr William Boothe Intralase, a start-up laser company from California put a laser on the market that performed the first step of Lasik in a more precise and safer manner than previous blades. Intralase had a great deal of difficulty getting the surgeons to buy and use the laser.

Corneal Abrasion - A scrape or scratch on the cornea, the front surface of the eye.
Corneal Ectasia - A complication of LASIK similar to the inherited condition of keratoconus. It can happen when the eye was over-treated by a LASIK procedure, so that not enough thickness is left in the cornea to contain the eye's internal pressure. That pressure pushes against the cornea and causes it to bulge outward. Vision then becomes progressively worse.

DR BOOTHE: Low Vision - Visual impairment ; usually less than 20/200 which obstructs daily activities but cannot be corrected with glasses or contact lenses.

Macula - An extra-sensitive area roughly in the center of the retina, which enables us to see fine detail and do activities such as reading. The center of the macula is the fovea, which has no nerve cells or blood vessels to interfere with vision, and this makes it the most sensitive area of the macula. It’s also the part of the eye which enables us to distinguish colors.

Refractive Lens Exchange (RLE) - Also known as Clear Lens Exchange (CLE). A surgery which removes the crystalline lens from the eye and replaces it with an intraocular lens (IOL). This is essentially the same surgery that is performed for cataracts, where the cloudy lens is replaced with a clear one, except that it’s done to correct the refractive error of myopia or hyperopia, rather than to remove cataracts.

Ghosting - A name for double vision. The eye sees objects in duplicate, with the second image fainter than the main one.

Glaucoma - (glaw-KOH-muh) An eye disease where pressure builds up inside the eye. If it isn’t diagnosed and treated, it can damage the optic nerve, reducing the field of vision gradually, until blindness results. It’s treated with special eye drops which lower the pressure.
