Dr. Boothe
For the past 20 years Laser Eye Center has been a leader in the Refractive Surgery Industry. As one of the largest refractive-surgery centers in California, our team of highly experienced Ophthalmologists has performed over 200,000 refractive surgeries. At Laser Eye Center we believe that in addition to experience, high quality of vision correction is the essence to a successful practice. Going beyond 20/20 is our goal. At the Laser eye center we offer the latest most advanced FDA approved technology to our patients so they can attain the best quality of vision available today. Dr. Boothe Eye Care
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.
Keratotomy- Keratos is the greek word for cornea, and otomy means to create an incision. Together they mean to create an incision in the cornea.
Good LASIK Candidates Must:
Be at Least 18 Years Old
Be in Good General Health
Have No Health Issues Affecting the Eyes
Have No Active Eye Conditions Which May Affect Healing
Have a Stable Vision Prescription for at Least One Year
Boothe Eye Center: 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.
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.

Microkeratome- A blade that creates a flap in the cornea during LASIK Surgery.
Iris- The iris is the colored portion of the visible eye. It is a muscle that affects the size of the pupil, depending on the amount of light needed to enter the pupil. Dr. William Boothe
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.
