LASIK vs. glasses Lit review
Briggs, Vantrice (2007,06,15). Lasik Vision Correction Surgery Vs Eyeglasses. LASIK eye surgery, Retrieved 02,20,2008, from http://www.lasikeyesurgery.com/lasik-articles/lasik-vision-correction-surgery.html
Millions of people have vision impairment. Most choose to get glasses, but there are many expenses and choices that have to be made with the decision to get glasses. Contact lenses are a more convenient choice for many people. There have been improvements made to both glasses and contacts but these improvements come with a price. The cost of a pair of glasses is at least $400. All of the choices of “transitions” or “scratch resistant” lenses only increases the price. Contacts have improved greatly with the technology of “extended wear” which can be worn for up to thirty days, but with this there is a cost. LASIK eye surgery is a new technology that reshapes the cornea. The price depend on the extent of the vision impairment. The cost of $300 to $1500 per eye can seem expensive until it is compared to the price of glasses and contacts over the years of use. LASIK also comes with a guarantee to last at least ten years. There is also an acuity plan that will plan free enhancements for the rest of you life. The entire procedure only lasts around ten minutes and often patients can experience immediate vision improvement. This surgery improves vision and saves time and money.

For sight Lit review

LASIK offers clear vision in minutes with little or no discomfort. This surgery may render contacts and glasses to become rare. People are becoming more and more exposed to the advantages of LASIK through print, radio, and TV advertising. These commercials usually give directions to the nearest eye care or surgery center. Refractive eye surgery is any surgery that has the goal of correcting eyesight. Earlier surgeries included radial keratotomy then photorefractive keratectomy. Today this surgery is less painful as a shot and only takes a few minutes to perform. The patient satisfaction is over ninety-five percent and vision is improved immediately. LASIK today is computer assisted which has revolutionized the cutting of the flap, to no longer be the “flap and zip“ procedure. The eye is numbed, an automated blade shaves back the outer layer of the cornea, the slice is moved to one side, and then the excimer laser vaporizes a small part of the underlying cornea. Then the flap is replaced and seals itself. As far as an elective cosmetic procedure, the only rival is liposuction. There are now advertising claims to the extreme and may be very difficult to get through. Advertising can make people believe that the cheapest deal is the best, but that is untrue because the surgery is only as good as the skills of the surgeon. Post problems include glare, light sensitivity, bad night vision, “star bursting” or a halo effect. Blindness is not a complication.

Patient who had previously wore contacts had less residual and a better outcome after surgery in the means of contrast and glare conditions. Patients who wore glasses were more likely to be over treated. This study by Dr. Tuan, was based on 131 patients who wore contacts and 25 who wore glasses. A follow-up was taken six months after the surgeries and the results show that those who wore soft contacts had a better contrast to sensitivity under photopic, mesopic and mesopic with glare. These results were statistically significant. Some of the contacts previously worn were the hydogel-type, which are left in place while sleeping. Dr. Bruce Nichols is the president of the Canadian Society of Cataract and Refractive Surgeons and a medical director at TLC Laser Centre in London, Ont; he states that the results of this experiment are surprising, but that surgeons know that soft contacts will result in thinner corneas. That is why they enforce the rule that no soft contacts must not be worn two weeks before surgery and no hard contacts must not be worn four weeks before. Thin corneas can cause a thin stromal bed which can lead to keratoectasia. All of the patients, no matter their past eye wear, were satisfied with the sharpness, day vision, and night vision. None of the patients suffered from dryness, blurriness, haloes, ghosting, or double vision.

Aging eyes Lit review

Eye surgery has been performed for the past thirty years for cataract patients to place lens implants in place of their lenses. Over 7 million people have had LASIK corrective surgery in the United States since the approval in 1998 by the Food and Drug Administration. LASIK is known for its painless cutting and reshaping of the cornea using a keratome blade and ultraviolet light. LASIK was started to only treat myopia and hyperopia, but now it is used to fix astigmatism and presbyopia. Presbyopia, or aging eyes, can be corrected by laser surgery with monovision. This is done by taking one eye, the dominant eye, and it is corrected to distance, while the other eye, the no dominate eye, is treated to better near vision. This can start out blurry and take getting use to, but is a lot more convenient than glasses. This eye problem is usually encountered mid-life and can effect anyone between the ages of 40 and 50. The risk is moderate to high even though the rate of complication is below one percent. Cost anywhere from 750 to 3,000 dollars per eye. The wide range is due to the different software the doctors can use to be more precise.

LASIK eye surgery has it’s pros and cons like any surgery. The risk of serious complications is small with a good surgeon and the best technology. It is important to get an evaluation because any decisions about medical procedures are very individual. You must be sure that you are a good candidate. Wasiuta, an astronomer, started experiencing distortions and blurring in his vision. After Venus turned into a “spiky blob” he followed all these procedures and was able to view nine stars in the Pleiades when before the surgery he could only see six. Three types of eye problems are myopia: Nearsighted with this you can see close objects, but not faraway ones. Hyperopia is farsighted with this faraway objects are clear and close ones are not. Astigmatism is when the image is blurred because or uneven focusing. The cornea provides two-thirds of the eyes’ refractive power, with the internal lenses providing the fine tuning. Data on outcomes show that six months after surgery that about three percent of people have some unresolved problem, and only 0.5 percent have a serious unresolved problem. The most common side effect of LASIK is dry eye, which causes an itchy and teary sensation. Now is the best time ever to have this surgery because of the technology and accuracy.

“LASIK was originally for therapeutic optometry and cataract removal. Medicare paid for cataract surgery so many patients took that step to improve their vision. Patients flew from Japan to have the procedure done” says Daniel Hunt. The technique has improved greatly in terms of comfort and recovery time. The Eyes of Texas medical center offer the IntraLase Method which is a 100 percent blade free surgery. The flap is created by an excimer laser. The excimer laser can be used to correct presbyopia which is the inability to focus sharply. A seventy-five-year-old can walk out with the vision of a twenty-year-old. Some clinics offer a full range of care including a free first exam, then the surgery followed up by a six month check up. Some also include free touch ups during the six months after the procedure. Dr. Smith of Eyes of Texas has performed thousands of surgeries and has performed about $600,000 worth of free eye-care for those who can not afford to pay. Surgeon Hunt from Texas says that safety is the number one priority even if it means that they have to turn a patient away for their own safety. Many vision correction areas offer promotions and anniversary specials.

The term laser is an acronym for light amplification by stimulated emission of radiation. Lasers are very useful because of their ability to be very precise and accurate. The use of a laser avoids cutting a flap with a blade and therefore is safer. The electromagnetic radiation of the laser is capable of altering biological tissues including photo-thermal, photo-disruptive, and photo-chemical. The excimer laser used in refractive surgery uses photochemical to break the chemical bonds and break molecules into fragments. The main advantage of lasers in refractive surgery is their ability to be switched off and on rapidly. The argon-fluoride excimer laser is the most common in sculpting the cornea. These lasers pulse output of the wavelength 193 nm. Each pulse removes only 0.21-0.27 pm of cornea tissue. This reduces the damage done to the other parts of the eye. The lasers are able to target specific tissues that absorb certain wavelengths. This reduces the damage done to the other parts of the eye. 1981 was the year that the US air force first reported the effects of the lasers on corneal tissue. Today about two thirds of patients after surgery have the vision of 6/6 or better. Some complications include haze, night vision problems, and blurring.

LASIK stands for laser in-situ keratomileusis. When correcting nearsightedness the curve of the cornea is flattened. This causes the light to be refracted onto the retina, which is in the back of the eye. This surgery can cost up to $2,500 per eye. This surgery is not covered by insurance. Surgeons believe that the use of glasses and contacts will disappear. There are 66 million people who use glasses and/or contacts. Most often both eyes are done at the same time, but the Food and Drug Administration recommends a three month waiting period after the first eye is done. The FDA has also prohibited against advertising of LASIK as safe and government approved. It is the doctors job to warn the patients of risks and alternatives. Be sure you know all the risks, discomfort, and expense. Your optometrist knows your eyes better than anyone and it is more likely to have a successful surgery if you get a surgeon who is skilled. Be wary of doctors who want to rush you to a decision or those who boast and are unrealistic of the surgery. In the end your decision should be made on your faith in the doctor. 65 percent of those treated had 20/20 vision or better and 95 percent had 20/40.

Types of eyesight problems corrected by LASIK
myopia-nearsightedness This occurs when the eye is too long, causing the focal point occurs too soon.
hyperopia-farsightedness This occurs when the eye is too short, causing the focal point to be beyond where it should be.
astigmatism-when the lens is not perfectly smooth. There could be a rough spot or it could be uneven.
The only thing that LASIK cannot fix or prevent is the loss of eyesight due to old age.
Contacts vs. Glasses vs. LASIK
Glasses were the first form of corrective eye wear, but there are disadvantages to them. Contacts became popular quickly because of the perks they have over glasses. Many people prefer contacts because they make them feel more attractive. Contacts are also better for athletes and active people. LASIK has all of the advantages of contacts and more. The morning hassle of getting the contacts in and the irritation of having them in too long is no longer a problem with LASIK. Besides these physical advantages there is the money savings. Every new pair of glasses and contacts can cost up to $500 (which need to be replaced every two years). LASIK is a life long fix for myopia, hyperopia, and astigmatism.
LASIK
This is a great image of LASIK eye surgery showing the steps. All of this can take as little as three minutes per eye.
What I Plan to do....
In this paper I plan to describe the reasons to get LASIK eye surgery, as compared to other means of eyesight correction, such as glasses and contacts. I plan to and already have used the research databases provided by UCA library to find information. With this information I plan to reword and combine with other information from actual medical sites and put it all into a logical and informative research paper.
More on LASIK compared to glasses and contacts
The cost and effort of LASIK eye surgery is a superior way to correct problematic eyesight compared to other methods in the way of overall price, immediate improvement, and overall improvement. According to Michael O’Keeffe eye-sight correction improved greatly when the microscope and laser came into use, the laser was introduced to eye surgery in 1979. O’Keeffe explains that in 1949 Harold Ridley invented what would now be called the contact lens. Today, according to Bob Holmes, in Contact Lenses: See Your Way to Savings, he states that 25 million Americans wear contacts. He goes on to say that this eye correction method could easily cost four thousand dollars over ten years counting the fifteen gallons of solution and the average new pair every two years. Vantrice Briggs gives information on the cost and hassles of eyeglasses in LASIK Vision Correction Surgery Vs. Eyeglasses. Briggs says that the cost of glasses are up to four hundred dollars per pair and most often those are replaced every two years. There have been many scientists that have researched LASIK eye surgery and it’s positive and negative effects. Most often the results after the surgery are remarkably different. There have also been many average people who have researched on their own time to find the “pros and cons” of the surgery for personal use. LASIK usually costs between one thousand to twenty-five hundred dollars but never calls for a “new pair”.
