The most common type of surgical vision correction, due to extensive advertising and promotion, is laser-assisted in situ keratomileusis. Of course, that's not what the advertisers and promoters call the procedure. Instead, it's known by its acronym, LASIK. With this type of laser eye surgery, a corneal flap is lifted, the eye is reshaped, and the corneal flap is replaced. The flap is created with the use of a laser. The eye is reshaped, depending on whether the person is nearsighted (myopia) or farsighted (hyperopia), by using an oscillating blade called a microkeratome. A computer guides the procedure for increased accuracy. In a newer operation, the microkeratome is replaced by a femtosecond laser which has proven to be more accurate. Laser eye surgery is a relatively quick operation that is performed on an outpatient basis. In most cases, the process is over in just a few minutes. But just because the process is simple doesn't mean that it's something to be done on a whim. The use of such unfamiliar terms as microkeratome and femtosecond laser should be enough for most people to realize that this is a serious surgical vision correction procedure that should be thoroughly researched.
Before undergoing surgery, the prospective patient will be required to have an eye evaluation. This allows the surgeon to determine the eye's shape and discuss different options with the patient. An individual may go into the surgeon's office believing that her eyesight will be miraculously transformed to 20/20. For the majority of patients, this is a realistic outcome. However, many individuals may find that their corrected vision is no better than 20/40. This is still acceptable, but not perfect. For a few individuals, perfect vision is an unrealistic expectation. Not even surgical vision correction can end dependence on glasses or contacts for people with very poor eyesight. The procedure may help sharpen visual acuity, but these individuals will still need to wear glasses or contacts. A reputable surgeon will discuss likely outcomes with the prospective patient so a good decision can be made on whether to go ahead with the procedure.
LASIK is not the only type of surgical vision correction. Some patients opt for a no-flap procedure. In photorefractive kertectomy, also known as PRK, an excimer laser is used to reshape the eye. Here again, prospective patients will want to do as much research as possible about the differences in procedures so that they can make the best possible decision. Basically speaking, surgery that takes less time and has less initial discomfort also has greater risk of future complications. A surgery that takes more recovery time often has better long-term results. Prospective patients may be interested in doing a side-by-side comparison of different surgical vision correction options. This comparison, along with the surgeon's recommendations, can help the individual in the decision-making process.
Prospective patients may want to do research on various eye surgeries before consulting a surgeon. There are just so many new terms to learn and they really should know what the words mean. And a prospective patient definitely will want to carefully choose the surgeon that is being entrusted with his sight. Consumer advocates warn individuals to not allow either price or easy financing plans to be determining factor when it comes to selecting a surgeon or eye surgery clinic. One's eyesight is much too important for money to be a primary issue. Wise individuals will look for a physician who has experience in advanced techniques, who answers questions clearly, and who has a broad knowledge of surgical vision correction options. The apostle John records the time when a blind man chose the Great Surgeon to heal his eyes. When asked about his newly-gained sight, John tells us: "He answered and said, A man that is called Jesus made clay, and anointed mine eyes, and said unto me, Go to the pool of Siloam, and wash: and I went and washed, and I received sight" (John 6:11).
There are other surgical vision correction options besides LASIK and PRK. Another type, known as laser thermal keratoplasty, or LTK, is especially for people who are farsighted and forty years of age or older. This technique zaps different places on the cornea to shrink the tissue. When people get to about age forty and older, their eyes don't focus the same as in their younger days. This is a condition known as presbyopia and is the reason that older people wear reading glasses. Some contact lens wearers even find it necessary to wear reading glasses in addition to their contacts to read fine print. Two more procedures are refractive lens exchange and implantable lenses. Anyone who is considering surgery should be aware of all the options instead of focusing only on the advertising hype that surrounds LASIK. Though this surgical vision correction option is the most popular and well-known, and works for many people, prospective patients should see if another option will work better for their individual circumstances. It can't be stressed enough that no procedure can be guaranteed one-hundred percent successful. This isn't a surgery that should be entered into on a whim. Instead, research into different procedures, treatments, surgeons, and clinics should be thoroughly undertaken. A well-informed patient will know the questions to ask and will have realistic expectations of the outcome. Armed with pertinent information and cared for by a respectable and knowledgeable surgeon, this individual will know what decision is best regarding surgery.
