LASIK Vision Correction Essay -- Lasik Seeing Eye blind Essays
LASIK Vision Correction      Are you ready to give up your glasses or contacts? LASIK vision correction is an up-and-coming procedure designed to reduce your dependence on glasses and contacts. My objective is to show both sides of the procedure, the risks involved and the wonderful possibility of not having to wear glasses or corrective lenses. Of patients with moderate vision impairments who have had the LASIK surgery performed, eighty-two percent achieve 20/20 vision or better and ninety-nine percent achieve 20/40 or better (May 60). However, LASIK vision correction is not for everyone. There are definite risks as well as possible side effects involved. Some of the side effects are hazing, night glare and halos, loss of vision, dry eye, infections and corneal abrasions.      LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering on the front of the eye, using an Excimer laser (â€Å"LASIK†). A knife, called a microkeratome, is used to cut a flap in the cornea. A hinge is left at one end of the flap. The flap is then 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 then replaced (â€Å"LASIK†).      Initial clinical trials of LASIK in the United States began in 1996 with Marc Michelson, M.D. being one of the first LASIK surgeons involved. These clinical investigations culminated in the approval by the FDA of the LASIK procedure in 1999 (May 20). â€Å"LASIK is the most popular refractive [or vision correction] procedure worldwide right now,†Marc Michelson tells WebMD (Braslavsky). Michelson says that because the LASIK procedure has become very popular lately, patients need to be careful when choosing a surgeon. He emphasizes the need for patients to seek out someone with experience and a long history of good outcomes (Braslavsky).      There are many factors taken into account before becoming a candidate for LASIK surgery. Candidates for LASIK surgery should be at least 18 years old and not be pregnant or nursing. Candidates should also have no active eye disease, a stable prescription for one year and have no restrictions mandated by their employer. Having realistic goals is also an important factor. Some common goals are: 1.     To be less dependent on gl... ...ford LASIK vision correction. This just is not the case. This surgery is quite expensive and results are not guaranteed. Surgical complications are estimated to occur in between 1.2 and 2.2 percent of patients. The CRS-USA LASIK Study noted that, overall, 5.8 percent of LASIK patients experienced side effects at the three-month follow up period (â€Å"Risks†). My attempt here was to show that there are risks involved with this procedure and to encourage research to be done before a decision is made. Corneal abrasions, infections, hazing, dry eye, loss of vision, and night glare and halos are among the many possible side effects. Are you willing to take the risk?      WORKS CITED Braslavsky, Andrea M, MS. â€Å"Keeping an Eye on Side Effects of Laser Eye Surgery.†     2001 Healtheon/WebMD. 13 Oct. 2001.          . â€Å"Lasik Eye Surgery: Learning About LASIK.†U.S Food and Drug Administration.           13 Oct. 2001. .
