Laser eye surgery is a vision correction option for many people with nearsightedness, farsightedness or astigmatism. These vision problems are called refractive errors. Laser vision-correction procedures reshape the cornea--the clear area at the...
In people with the eye disorder astigmatism, the light coming into the eye becomes focused in two places instead of being pinpointed down to a single spot at the back of the eye. This can induce blurry vision, headaches and eye strain. Astigmatism...
LASIK eye surgery is a surgical procedure in which lasers are used to reshape the thin layer of the eye called the cornea. This can dramatically improve vision. According to Medline Plus, LASIK eye surgery is a quick outpatient procedure that...
People with vision abnormalities often consider using contact lenses or laser eye surgery instead of eyeglasses. There are several facts to keep in mind about these methods of vision correction when making a decision between them.
LASIK, or Laser-Assisted In Situ Keratomileusis, is a surgical procedure that is done on the eye to correct vision. Most people who have LASIK done do not need to wear contact lenses or eyeglasses anymore. It is important to carefully consider...
LASIK is a corrective eye procedure designed to free patients from the need for glasses or contacts. LASIK is an acronym for laser-assisted in situ keratomileusis. The surgical procedure permanently changes the shape of the cornea, which is the...
Laser-assisted in situ keratomileusis, or LASIK, is a surgical procedure performed on the eye with the goal of correcting vision problems entirely or reducing dependency on contacts or eyeglasses. The process goes like this: A laser or blade cuts...
LASIK (laser-assisted in-situ keratomileusis) is a common type of eye surgery that permanently alters the shape of the cornea--the transparent covering on the front of the eye--in order to improve vision and lessen or eliminate the need for eye...
Lasik is a type of eye surgery that is intended to improve vision. It is an acronym for laser-assisted in-situ keratomileusis. It is a type of refractive surgery, which means it changes the shape of the cornea. The cornea is the clear membrane...
Gradual vision loss can lead to near- or farsightedness, making objects appear blurry and hard to make out. In the past, treatment options included corrective lenses. Contact lenses and glasses seemed to be the only recourse for correcting vision...
Also called myopia, nearsightedness is a visual problem that occurs when the eyeball is unusually long from front to back. This effects the way the retina receives the light rays that form visual images and as a result causes blurring of distant...
LASIK stands for laser-assisted in situ keratomileusis, a common vision correction procedure. During this type of refractive surgery, a flap is created in the cornea, the laser is used to remove tissue from the cornea and the flap is rolled back...
Lasik is surgery on the eyes to improve the vision, often eliminating the need for contact lenses or eyeglasses. The word Lasik means laser-assisted in situ keratomileusis, notes the Food and Drug Administration. This procedure modifies the shape...
LASIK surgery is a type of corrective eye surgery that eliminates the need for further visual assistance such as eyeglasses or contact lenses. LASIK (an acronym for laser-assisted in situ keratomileusis) is performed when a doctor uses an eximer...
Surprisingly, the theory behind Lasik surgery--reshaping the cornea to correct errors in refraction--has been around since the 1800s. Even the laser itself has been in use since the 1970s. Despite that longevity, having a laser shot into your...
Lasik, or laser-assisted in-situ keratomileusis, is a popular outpatient eye surgery done to improve vision by altering the shape of the cornea, the membrane that lies in front of the iris, the colored part of the eye, and the pupil. Reshaping the...
LASIK eye surgery is a common procedure done to correct vision problems. It involves the use of lasers to reshape the eye. The price of the operation varies, but can cost up to $2,000 per eye, as of 2010. However, technological advances have...
Laser-assisted in situ keratomileusis (LASIK) surgery helps those who need corrective lenses. By reforming the cornea, patients' vision return to normal, or close to normal. As a result, most patients no longer require glasses or contact lenses,...
Various methods of correcting vision are available, the most popular being eyeglasses and contact lenses. The Vision Council of America states that three out of four adults need corrective lenses, and about 64 percent of adults wear glasses. In...
Just a few decades ago, people who needed glasses or contact lenses wore them their entire lives. Today, people with refractive errors such as nearsightedness or farsightedness can permanently correct their vision surgically, and abandon glasses...
Routine eye exams help doctors monitor eye conditions, and when the doctor feels a surgical procedure may improve health or vision in the eye, he will discuss these options with the patient. In some instances, the patient does not have to make an...
LASIK (laser in-situ keratomileusis) surgery is a laser-assisted form of eye surgery that can correct nearsightedness, farsightedness and other vision problems. It is a form of refractive surgery (surgery that changes the curve of your cornea)...
Laser-assisted in situ keratomileusis (LASIK) surgery helps people who regularly use corrective lenses. The surgery itself reforms your cornea, with the goal of removing any need for glasses or corrective lenses. Occasionally, you may still need...
Your eye doctor can determine an ideal prescription strength to correct your astigmatism. You'll likely need to take an array of tests, including a slit lamp examination and a visual acuity test. Your optometrist will also play with various...
Cod liver oil does not heal farsightedness, medically termed hyperopia; if it did, far fewer children who were made to swallow cod liver oil daily would have needed glasses in the first half of the 20th century. While cod liver oil does have...
Lasik, or laser-assisted in situ keratomileusis, is a form of eye surgery used to correct astigmatism, farsightedness and nearsightedness. While most people undergoing Lasik surgery are pleased with the outcome, a small percentage of patients...
The brain interprets visual impulses transmitted through the photoreceptors of the retina, to the optic nerve and the brain. Many eye diseases and disorders cause an interruption to the normal pathway for perceiving and interpreting images. Eye...
Astigmatism is a treatable eye condition that results in blurred vision. It occurs when the front of your eye, which is also called the cornea, or the lens develops a different curvature in one direction. Typically, the cornea is smooth and even...
Many millions of people have one type or another of difficulty with their vision. For much of history, the only treatment option for vision problems was the use of eyeglasses, but in recent years a variety of different surgical procedures have...
