Wavefront Lasik Eye Surgery
Wavefront LASIK eye surgery is available for people who have some very complex prescription needs that are impossible to obtain with regular LASIK procedures. When a person eschews glasses or contact lenses, there really is no other place to turn but to corrective surgery for the answer. In some cases, a person may not want to stick with glasses because of the type of occupation he or she is in, including aviation or perhaps some underwater work. Contact lenses are often the choice of athletes who need vision correction but want to bypass the wearing of glasses. But in some cases, especially with high contact sports, contacts can also pop off the eyeball, or slip into a corner of the eyeball causing the player to have to leave the game or call for a timeout. In decades past, complex vision prescriptions could only be handled by the wearing of glasses, and then began a revolution in the design of contact lenses, opening a whole new world to those whose vision could once only be corrected through lenses held on the face with frames. But now, with the debut of wavefront LASIK eye surgery, even complex surgery can be performed on the cornea, making even some of the toughest prescriptions now possible to be corrected without having to wear glasses or contact lenses.
Hyperopia, the formal word for farsightedness, occurs when the eyes' lens is misshapen enough to cause the light coming into the eyeball to focus behind the retina. Myopia, the formal word for nearsightedness, is caused when the light focuses in front of the retina. Those with hyperopia cannot see objects close up but can read the "All You Can Eat Buffet" sign three hundred feet up the road and those with myopia can read just fine but have difficulty reading the "Last Chance for Gas Next Fifty Miles" billboard several hundred feet away. Astigmatism, caused by the lens being wavy in several directions, makes overall vision kind of blurry. But what happens if a person has a combination of all these types of vision problems? Then it is time for wavefront LASIK eye surgery, a breakthrough procedure for the patient cornea that has many anomalies.
Some people call wavefront Lasik eye surgery customized vision surgery because it is handled in a different manner than mere hyperopia or myopia corrective procedures. Results from this technique for vision correction occur from three dimensional measurements of the eyeball. These three dimensional figures guide the laser to make cuts that would be impossible with the traditional laser operation. The proponents of this procedure say that the operation can not only help people see more, but actually see better in terms of contrast and detail. This often reduces some of the risks of traditional LASIK operations which can sometimes cause vision to produce halos, glare and difficulty with night vision. In fact, those who have had poorer vision as a result of prior LASIK surgery can often have it corrected with wavefront LASIK eye surgery. Many ophthalmologists now say that the wavefront technique is far superior to conventional LASIK surgery and over 75% of these vision surgeons now use it in standard practice.
In most cases, the process for wavefront LASIK eye surgery happens after the patient is seated in a chair and light is beamed into the eye. The pattern of the eye is then detected by the light and returned back to the emitting machine where the eye is "mapped" for aberrations. This map of the eye enables the laser to be able to follow a very precise cutting pattern, making for a much more effective procedure in correcting vision problems. Eyesight, perhaps our most cherished of the senses, is a horrible tragedy when lost. But Jesus said something else lost is beyond tragic. "For what shall it profit a man if he should gain the whole world and lose his own soul? Or what shall a man give in exchange for his soul?" (Mark 8:36-37)
When a person decides to have wavefront LASIK eye surgery, the cost is significantly more than with traditional LASIK surgery. Of course, from state to state and region to region the cost is higher or lower. For instance, does anyone want to pay for any medical services located on 5th Avenue in Manhattan or Rodeo Drive in Beverly Hills? One of the reasons it is higher is because the physicians who use the technology must pay a royalty to the company that made the wavefront technology. But it is not a cure all for all eye issues. In fact, a person must be ready to hear that they are not a candidate for this surgery. There are strict Federal Drug Administration guidelines that a person's vision must meet in order for a doctor to legally and ethically use wavefront LASIK eye surgery.
Choose your eye surgeon carefully by checking references and former patients who have his or her services. Not all surgeons, although they have graduated from medical school and have diplomas have the same skill levels. Do not assume that a lower priced wavefront procedure is a good deal. After all, you are not buying a Volkswagen built in the same factory in Germany as one sold 400 miles away. These are your eyes we are discussing and as much deliberation and investigation should be used until the patient is absolutely relaxed in the doctor's operating chair, knowing he is getting the best care possible.
Custom Wavefront LasikProcuring custom wavefront lasik surgery leads to better visual acuity, a higher quality of vision, and faster visual recovery than standard vision correction procedures. "Laser-assisted in situ keratomileusis" is the medical term for the lasik procedure. Lasik is a refractive eye surgery accomplished with the use of laser technology. During the assessment phase for eligibility, age, occupation, and lifestyle must be taken into consideration. Yet and still, more than 700,000 Americans have a lasik procedure done annually. The U.S. Patent Office granted the first patent for LASIK to Dr. Gholam A. Peyman on June 20, 1989. The patent secures a "Method for modifying corneal curvature," that is done in a certain fashion. Ophthalmologists use this procedure for a variety of eye conditions. Lasik can correct astigmatism, myopia, and hyperopia. Astigmatism is a visual defect, usually with the cornea, that prevents clear focus. Astigmatism is often hereditary, but could also develop from incorrect posture or overutilization of the eyes for close-up work. Myopia is simply nearsightedness; the inability to see objects clearly at a distance. And hyperopia, which is the opposite of myopia; the inability to see objects clearly; close up. Though there are other procedures available for these surgeries, custom wavefront lasik has won out as the preferred option.
Different from traditional lasik, wave-front-guided refractive surgery creates a highly detailed "map" of how light moves through the person's eye. The procedure is able to detect even the most minute distortion of focus. Using this procedure, the ophthalmologist can reduce the chance of glare, light "halos," and poor night after-surgery. Even though the procedure may technically be more accurate than previous surgery types, selection of an appropriate patient and obtaining high quality wavefront data are just as important to the success of custom wavefront lasik surgery as meticulously managing changes that will occur during the healing process. Generally, when done right there are far fewer retreatments and increased patient satisfaction. From the time that the FDA approved of wavefront-guided refractive surgery, there have been ongoing significant advances. Increased service offerings are available because of these technological improvements along with better surgeon skills. Because of this, more people have become eligible for customized procedures.
The underlying principle of custom wavefront lasik is the accurate assessment of the aberrations of the eye. An aberration is an irregularity. Using iris registration technology and pupil centroid compensation, surgeons get a more accurate sense of the optical errors they will encounter and thusly must correct. There are now options for custom wavefront lasik for people who have mixed astigmatism, as well as myopia with astigmatism. Research and practice have enabled doctors to start with better data, use more accurate equipment, and frankly, realize more predictable post-op outcomes; than ever before. The eye alignment is measured using an aberrometer. The aberrometer reading before and during surgery must match exactly. An inaccurate reading will cause the surgeon to over correct or under correct the aberration; leaving the patient, at best, in a similar visual condition, and at worst, worse off. The good news is, of surgeries for moderate to severe nearsightedness, nearly 95% have achieved 20/20 vision or better. "Cursed be he that maketh the blind to wander out of the way. And all the people shall say, Amen." (Deuteronomy 27:18)
There are no standardized costs for custom wavefront lasik, nor for any of type of vision correction surgery. However, lasik, using a bladed instrument, hovers around $1,500 per eye. While general laser eye surgery, tends to average $2,000 per eye. Wavefront-guided lasik, is only about $350 more per eye. A person should be particularly suspicious of advertisements that promise procedures starting at $500 or even $1,000. Only about 10% of eye surgeries are less than $1,000 per eye. A peak at the fine print will tend to show that very few people (the exception and not the rule) would ever be eligible for such procedures. The main costs in these surgeries are for the expertise and the technology that allows the doctor to be extremely accurate in measurements and subsequent operation. The equipment and the training costs lots of money. That is the rationale for the bill being so high. Using a doctor who does not have the latest equipment or the most recent training may cause deep regrets in the end. There is hope that costs will continue to fall for custom wavefront lasik. As more doctors are trained and more equipment is produced, the prices will tend to fall.
Seeing is a critical body function. Maintaining good eye health and vision, is therefore important to most people. However, when there is a problem seeing, the old method of dealing with the issue was to prescribe lenses. These could be glasses or contacts. Either one pales in comparison to being able to see with the naked eye. Technological advances and willing surgeons have made it possible for many more people to go without eye wear and accessories. If there is currently nothing wrong with a person's eyes, it's a good time to see an eye health-care provider. At least once a year, a person should have their eyes examined. Furthermore, if a person has any degree of unusual eye irritation, eye pain, or sudden loss of vision they should run (don't walk) to see a doctor. Too many eye conditions cause irreparable and irreversible damage. But, for those who are born or develop correctable conditions, custom wavefront lasik is the way to go.
