masks - Masks are used in PRK surgery to modify the removal of surface tissue by the laser. PRK surgery involves the removal of or fashioning of concave (myopic) or convex (hyperopic) lenses on the corneal surface. Most refractive errors also include some element of astigmatic irregularity. Most excimer laser machines employ different kinds of masks to customize, refine and smooth the corneal surface. Many machines have an internal constricting diaphragm (like a camera f-stop mechanism) as an internal mask for use in treating Myopia. One manufacturer uses an extra material applied unto the cornea (an ablatable or destroyable mask) for treating astigmatism. Another manufacturer uses a different shaped metal mask for treatment of hyperopia or myopia. Variable rotation of the masks is used to deal with astigmatism

Penetrating Keratoplasty (PK) - A corneal transplant. A full-thickness, circular piece of the cornea is removed and replaced by a similar piece from a donor. It can restore vision to an eye which had previously been blind.

Misalignment of the eyes in childhood should be corrected as soon as possible, so that binocular vision (the brain’s ability to use both eyes together) can develop and amblyopia can be avoided. Surgery may be needed; or glasses, an eye patch, or other types of treatment.

As we age, the lens of the eyes becomes rigid, loses its flexibility, and thus its ability to focus as well. The exact cause of presbyopia is still under research and debate. One theory is that the fibers in the lens become stiffened and are unable to change shape as well. Another theory is that the lens grows too big and is not able to change shape as well. Other factors such as trauma, occupation, and lifestyle may be factors as well.
There are several types of glaucoma, the most frequent one being Open-Angle Glaucoma, which has no obvious symptoms at first. About 15% of glaucoma cases are Closed-Angle Glaucoma, and there are noticeable symptoms, such as nausea, eye pain, blurred vision, and headaches. There’s also Normal-Tension Glaucoma, where the intraocular pressure doesn’t build up, and no cause has yet been established for this yet, although there are theories.

LASIK DALLAS - Dr William Boothe: In Situ means "in place" or not removed.

Iris is the colored ring of tissue suspended behind the cornea and immediately in front of the lens.

Keratectomy is the surgical removal of corneal tissue.

pinguecula - A yellowish spot seen on the white of the eye at the junction of the clear cornea and white sclera of the eye. These lesions are usually caused by UV radiation. The white surface of the eye cannot "tan" and therefore cannot protect itself from sunburn.

presbyopia - "Old eye" is a condition in which the ability to accommodate for near vision falls off because of loss of elasticity of the crystalline lens of the eye and weakness of the ciliary muscle. The individual is no longer able to read clearly and requires reading glasses.

ABO - American Board of Ophthalmology, a medical specialty board which offers education and examinations for ophthalmologists. Upon completing this 1 ˝ year program, the ophthalmologist is Board Certified.

Abrade - To roughen by rubbing or scraping, thus removing small pieces of surface tissue.
