LASIK DALLAS - Dr William A. Boothe Refraction - The bending of light rays. To have clear vision, the eye must focus light rays on the retina, which means bending them as they enter the eye. Two structures in the eye perform refraction: the cornea and the crystalline lens.
LASIK EYE - Dr William Boothe DSAEK - DSAEK (Descemet's Stripping Automated Endothelial Keratoplasty) is a new procedure devised in 2007 for improving a corneal transplant. Descemet's Membrane (named after French physician Jean Descemet (1732-1810), is the basement layer, the innermost of the cornea's five layers. DSAEK transplants only this very thin layer rather than the entire cornea. The replacement layer from a donor stays in place without the need for any sutures. Recovery from DSAEK is one to three months, as compared to the one to two years' recovery required by a full corneal transplant.

DR WILLIAM A. BOOTHE: Photorefractive Keratectomy (PRK) - A refractive surgery like LASIK, where an excimer laser is used to reshape the cornea and correct myopia, hyperopia and astigmatism. It’s used for those who have corneas too thin to tolerate a LASIK procedure. Instead of the microkeratome being used to create the corneal flap, the laser is used, which can do it even more precisely and subtly than the microkeratome.

So many companies offer a range dealing specifically with contact lenses and dry eyes that it pays to experiment and shop around and compare ratings. Dr William Boothe at ClearBlogs. It's not only specific types of contact lenses that can help with dry eyes. There are solutions that are aimed at working alongside contact lenses and dry eyes to minimize the risks; theses include tear inducing solutions and artificial tears.

By comparing brands and manufacturers, the perfect contact lens will be found.If irritation of the eyes continues, the contact lenses should be removed immediately and a health care professional consulted.

DALLAS LASIK - DR WILLIAM BOOTHE: Vitreous Fluid - The jelly-like fluid that fills the main part of the eye, between the lens and the retina. It’s clear so as to give light rays an unobstructed path to the retina, and to keep that clarity, it contains phagocytes, cells which ingest and destroy foreign matter.
Vitreous Humor - The transparent gel that fills the space inside the eye behind the lens and in front of the retina.

Glare is scatter from bright light that decreases vision.
Halos are rings around lights.
Haze is corneal clouding that causes the sensation of looking through smoke or fog.
LASIK DALLAS - DR WILLIAM BOOTHE 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.
