Dry Eyes After LASIK - Some patients may experience dry eyes after LASIK and PRK. Often it is a temporary side effect during the healing process. If a patient is prone to dry eyes, our medical teams may discuss options with the patient, or discuss non-candidacy if the patient's eyes are too dry to have laser vision correction. Boothe Eye Care
Optometrist- An optometrist is a doctor whose specialization is vision. An optometrist can diagnose vision concerns, treat vision concerns, manage vision concerns.
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.

Keratomileusis- Keratos is the greek word for cornea, and mileusis means to reshape. Together they mean to reshape the cornea.

Have No Active Eye Conditions Which May Affect Healing
Have a Stable Vision Prescription for at Least One Year Dr. Boothe Eye Care
LASIK
LASIK is a more complex procedure than PRK. It is performed for all degrees of nearsightedness. The surgeon uses a knife called a microkeratome to cut a flap of corneal tissue, removes the targeted tissue beneath it with the laser, and then replaces the flap.
"With LASIK, the skill of the surgeon is important because he'll be making an incision," says Stephen Crawford, O.D., an optometrist practicing in Virginia, "compared to the PRK method where the machine does more of the work." Crawford urges people to find qualified, experienced doctors to perform this surgery. "You'll want someone who's done a number of LASIK procedures since this is a surgeon-dependent operation," he said.
According to Ken Taylor, O.D., vice president of Arthur D. Little, Inc., a technology and management consultant firm in Cambridge, Mass., "Last year, across the country, 40 to 45 percent of refractive surgeries performed by physicians were LASIK, which equates to approximately 80,000 procedures." Doctors not participating in clinical trials may choose to use the approved laser to perform LASIK procedures at their discretion, says Morris Waxler, Ph.D., chief of FDA's diagnostic and surgical devices section. But most uses are considered "off label" and are not regulated by FDA.
Boothe Eye Center LADAR
Using laser and radar technology developed by NASA, LADARVision® was the first approved system with active eye tracking, which compensates for involuntary eye movements. Although other laser systems have now developed eye-tracking systems, LADARVision® has the only system utilizing laser radar tracking technology, a system that measures eye movement 4,000 times each second and is capable of following eye movements regardless of how rapid or erratic they may be. Successful laser application does not rely on your ability to hold your eye perfectly still.
