WILL MY IMPROVED VISION BE PERMANENT?
LASIK with LasikPlus Vision Centers is designed to be a permanent correction for your vision. Studies to date show excellent vision stability for more than a decade following treatment. LasikPlus also offers an opportunity to participate in a LasikPlus Lifetime Satisfaction Plan. Because the FDA does not allow guarantees on a medical procedure, we wanted to offer patients some kind of peace of mind. A Lifetime Acuity Plan allows patients to have laser vision correction again, at no cost. Of course this only covers vision degradation related to corneal problems: nearsightedness, farsightedness, and astigmatism. The details and restrictions will be covered by the medical team.

Myopia- Myopic people typically have difficulty seeing objects at a distance. Myopia can be so severe that people have difficulty seeing objects up close too.

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 the FDA regulates
In the United States, the Food and Drug Administration (FDA) regulates the sale of medical devices such as the lasers used for LASIK. Before a medical device can be legally sold in the U.S., the person or company that wants to sell the device must seek approval from the FDA. To gain approval, they must present evidence that the device is reasonably safe and effective for a particular use, the "indication." Once the FDA has approved a medical device, a doctor may decide to use that device for other indications if the doctor feels it is in the best interest of a patient. The use of an approved device for other than its FDA-approved indication is called "off-label use." The FDA does not regulate off-label use or the practice of medicine.
Dr. Boothe Eye Center: Lens- The lens of the eye is the body between the iris and the vitreous humor that focuses light rays entering through the pupil to form an image on the retina. You may also want to research presbyopia.

Presbyopia:
LASIK surgeons cannot correct this age-related vision problem; it occurs in most individuals starting in the early 40s and progresses with age.
Muscles inside the eye lose flexibility and reading can become difficult.
People may have presbyopia in combination with another vision problem like nearsightedness.
The nearsightedness would be correctable by LASIK surgery, but the presbyopia would not; however, we may be able to find an adjustment to compensate for both.

Farsightedness- Farsightedness is another name for Hyperopia or Hypermetropia. Many Farsighted patients have difficulty seeing things up close, and often have crisp-acute distance vision. Boothe Eye Care

Keratectomy- Keratos is the greek word for cornea, and ectomy means to remove. Together they mean to remove corneal tissue.


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.


Pupil- The pupil is the dark opening in the visible eye. It will open when more light is needed to see, and it will get smaller if less light is needed to see.

Astigmatism:
Astigmatism causes a distortion of vision, where a person may experience an overall blurriness. Information regarding an astigmatism is found in the cylinder column. Many people with myopia or hyperopia have some degree of astigmatism

Refractive Error- This word refers to vision problems associated with the cornea: Astigmatism, Hyperopia, and Myopia.

Diopter- A diopter is one whole number on a prescription. The number of diopters on your prescription represents how much correction is needed to normalize your vision. The more myopic or hyperopic you are, the higher your prescription will be represented in diopters; or rather the farther away from zero your prescription will be.

HOW LONG WILL MY LASIK PROCEDURE TAKE?
The LASIK procedure time is between five and fifteen minutes. We ask our patients to plan to be with us for approximately two hours on the day of their treatment. This gives our medical team adequate time for your procedure preparation, additional paperwork, final examination, and give you an opportunity to ask questions after your vision correction.
Boothe Eye Center
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.

Other types of refractive surgery
Radial Keratotomy or RK and Photorefractive Keratectomy or PRK are other refractive surgeries used to reshape the cornea. In RK, a very sharp knife is used to cut slits in the cornea changing its shape. PRK was the first surgical procedure developed to reshape the cornea, by sculpting, using a laser. Later, LASIK was developed. The same type of laser is used for LASIK and PRK. Often the exact same laser is used for the two types of surgery. The major difference between the two surgeries is the way that the stroma, the middle layer of the cornea, is exposed before it is vaporized with the laser. In PRK, the top layer of the cornea, called the epithelium, is scraped away to expose the stromal layer underneath. In LASIK, a flap is cut in the stromal layer and the flap is folded back.

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.

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.

LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A mechanical microkeratome (a blade device) or a laser keratome (a laser device) is used to cut a flap in the cornea. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middlesection of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma and the flap is replaced. There are other techniques and many new terms related to LASIK that you may hear about.
