Eye Correction Surgery
Eye correction surgery is now becoming a popular option for people who have less than perfect vision. Many people find that glasses and contacts are a burden. People who wear glasses or contacts can't swim in them. They must remove contacts and glasses at night before going to bed. Vision with glasses is limited to certain angles. Laser eye correction can improve sight tenfold and do away with all of the inconveniences of glasses and contacts. Many people say that they have the best sight of their life after their treatment. There have been many success stories, and the treatment is constantly growing in popularity, not to mention in technological advancements. This surgical procedure is also called refractive surgery. It is widely available today, and it may just be the solution for the person who wants to see better.
Eye correction surgery reshapes the transparent front part of the eye, the cornea, so that light can focus correctly on the retina in the back of the eye. There are several different types of treatments. Whatever problem with his vision, the consumer may find just what he needs in this new area of medicine. Astigmatism can be corrected with certain types of treatments that are new on the market. Nearsightedness can be treated with many other types, and farsightedness can be treated with others. LASIK is actually short for laser insitu keratomileusis. In this surgery, the underlying tissue is accessed through a flap in the outer layer of the cornea. LASEK is short for laser epithelial keratomileusis. In this surgery, the eye is not scraped or cut. The flap is created with an alcohol solution. ALK, or automated lamellar keratoplasty, is done by making an incision in the sub layer of the cornea. This treatment is for people with severe nearsightedness and slight farsightedness.
AK, also known as astigmatic keratotomy, is a treatment used to correct astigmatism. Technically, it is a surgical procedure. Astigmatism is caused when the normally round cornea assumes a football shape. AK incisions makes the cornea round. These incisions force the cornea to relax. PRK, or photorefractive keratectomy, on the other hand, is used for mild to moderate nearsightedness, farsightedness, and also astigmatism. Laser eye correction is used to reshape the cornea as well. The laser is used on the surface of the cornea so that no cutting is involved. LTK (laser thermokeratoplasty) is another option for farsightedness and astigmatism. The heat of the laser is used to shrink and reshape the cornea. Like PRK, there is no cutting involved, nor any tissue removal. Though less popular today, RK, or radial keratotomy, is used to correct nearsightedness. It is quickly becoming obsolete compared to LASIK and PRK.
Laser eye correction can be a major blessing to anyone with poor vision. However, the patient must consider possible side effects. In some cases, people come out of treatment with worse vision or their vision returns to its original state after the surgery. Others experience infection or delayed healing after the procedure. Other possible side effects include the halo effect, undercorrection, overcorrection, excess corneal haze, and flap damage or loss, although this risk only comes with LASIK. Still, there are other things to consider when thinking about eye correction surgery. The patient must find out if his insurance company will cover the majority of the costs. The patient must contact his insurance company before scheduling the first appointment. Also, different procedures have different recover times, which needs to be accounted for before the treatment begins. Other problems with the procedures is that the patient will not be able to drive for a few hours or days.
The person considering any type of eye surgery should take his time making this important decision. Eyesight is a priceless gift from God that we shouldn't take for granted. Solomon writes, "The hearing ear, and the seeing eye, the LORD hath made even both of them" (Proverbs 20:12). We shouldn't rush to judgment just because we have listened to someone's story of a miracle cure. We must carefully weigh all the consequences. Clinics and doctors who offer laser eye correction can be located almost anywhere in the United States. The Internet is full of resources for the procedure. The consumer can consult his local phonebook to choose a clinic or doctor and for seeking out recommended doctors and clinics in his state. He can ask friends and family for their recommendations. He should check for complaints against the professionals through the Better Business Bureau or other organizations and learn out how many years the doctor and clinic have been doing eye correction surgery. It is important that they have years of experience and possess the latest technologies. Contact the facility and doctor and request an appointment to sit down and discuss options. Most likely, they will start by giving him an eye exam to fully understand his vision correction needs. Pursue the laser eye surgery options they give only if he feels comfortable with the clinic and doctor.
Eye Laser SurgeryEye laser surgery is for those that have inhibited vision due to nearsightedness or farsightedness and desire a permanent solution to this vision problem. In order to understand how procedures of this nature work, the concept of how vision in the human body works must first be explained. The eyes are perhaps the most important sensory organ. They provide people with countless pieces of information, such as the size and shape of objects, colors, distance, and movement. A person without sight cannot read a newspaper, drive a car, watch a movie, catch a ball, or do many other things that people with sight can easily do. Seeing is a complex process. Eye surgery enhances a person's seeing ability, and it is no wonder this procedure is one of the hottest growing surgeries existing today. Many ask the question of what sight really is. The answer can be found in science. "For he hath not despised nor abhorred the affliction of the afflicted; neither hath he hid his face from him; but when he cried unto him, he heard." (Psalm 22:24)
Eyes, nerves fibers, and the brain are the three components needed to produce sight. The eyes alone cannot see anything without a brain to interpret the images and without nerve fibers to relay the messages. Sight begins with light entering the front of the eye by passing through the clear cornea and lens. The cornea is what is manipulated during eye laser surgery. These structures bend the rays of light to focus an upside down image on to the retina, which is the lining on the back of the eyeball. Corrective eye surgery is primarily associated with only the cornea and not the retina. The retina contains specialized cells that are sensitive to light. When light strikes these cells, they send a message along the optic nerve that leads from the eye to vision centers in the brain. In the brain, the messages are interpreted and then a person can see.
The eyeball is nearly round and about the size of a ball used for table tennis. Its outer surface is a tough protective layer made up of the sclera and the cornea. The sclera is white and forms most of the outer surface at the sides and the back of the eye. Attached to the sclera at the front of the eye and bulging slightly is the clear cornea. Eye surgery focuses more on the cornea. The cornea's curved shape bends light rays and helps direct them towards the back of the eye. If the cornea's curve is slightly off shape, such as peeking too high, or lying too flat, it results in nearsightedness or farsightedness. Eye laser surgery combats that problem by smoothing out a higher peeking cornea to correct the bending of the light rays which improves vision, or by raising the curve in order to bend the light rays more correctly to improve vision. General procedures can be used for a number of problems, but typically they have to do with the curve in the cornea.
The most common disorders that affect the eyes and require surgical care are problems in the focusing power of the cornea and lens. These problems can often temporarily be corrected by eyeglasses or contact lenses. In a person wanting eye laser surgery with nearsightedness, the focal point is in front of the retina instead of directly on it. This results in an inability to focus clearly on distant objects, such as words on a blackboard or traffic signs. For individuals needing corrective eye surgery for farsightedness, the image is focused behind the retina. This results in the inability to focus clearly on objects close up, such as words on a page. As people get older, their lenses become less rubbery and cannot focus easily. This condition, called presbyopia, is one of the reasons why some people with good vision when young, need glasses in middle or old age.
A surgical procedure can also be an option for those that suffer with astigmatism. This is when they have unevenness in the surface of the cornea. This causes a portion of the object to begin focus and the remainder of the object to be out of focus. Some cases can be corrected through eye laser surgery. Infections sometimes develop. Conjunctivitis is an infection of the moist tissues. A stye is a swelling in the eyelid caused by an infection of a small oil gland and can be treated through eye surgery. Cloudy areas in the lens, called cataracts, can develop in older individuals. The cloudy lens can be removed through surgery and replaced by a clear plastic lens. These procedures can lead to wonderful results, where individuals with poor vision have the ability to again see clearly. It is important to consult with a doctor before making the decision, in order to determine the best plan of action.
