Nearly everyone suffers some sort of vision aberration such as glare and having trouble seeing at night, but unless they cause major problems with sight, are usually nothing that raises concern. When choosing lasik eye surgery, some patients may be determined a candidate for wavefront lasik eye surgery, which will not only help them with how much they see, but all how well they see it.
Lasik eye surgery users lasers to reshape the front of the eye, the cornea and can usually benefit those patients suffering from nearsightedness, far sightedness and astigmatism. However, many lasik surgery patients may also continue to suffer some of the other vision problems such as halos, seeing a light surrounding an object, along with visual blurring, double vision and seeing a starburst pattern. Many of these problems might be corrected with custom lasik eye surgery, a process known as wavefront lasik eye surgery.
With lasik eye surgery, the laser's focus is in reshaping the corner to provide better focus of the light passing through the cornea and onto the lens in the back of the eye. With wavefront lasik eye surgery, a three dimensional map of the eye is created to determine how the light is focused on the lens and make corrections to the cornea to better focus the amount of light admitted. This process can not only improve the patient's vision but also how well their vision interprets the objects they see as well as an improvement in fine details and the sensitivity to contrast.
Some of the reported side effects of laser eye surgery include patients seeing halos around objects, as though a light is located behind the object, which is not usually the case with custom laser eye surgery. How much as person can see is determined by some of the refractive qualities of the eye, affected by such things as myopia, hyperopia and astigmatism. How well a person sees is affected by shadows, halos, blurring and other so-called higher order aberrations.
Once a patient has been determined to be candidate for wavefront lasik surgery, they have a better chance of achieving near-perfect vision of 20/20 with some having greater than 20/20 vision. They also have less instances of losing their surgically corrected vision over time and usually maintain the quality of their vision and the sensitivity to contrast. There is also a reduced chance of them suffering from problems with night vision and glare.
There remains a lot of discussion on the benefits of wavefront lasik surgery over typical laser eye surgery with some laser eye surgeons claiming that neither procedure can be used to treat or cure some of the high order aberrations. Despite the disagreement over the benefits by lasik eye doctors, nearly 75 percent of laser eye surgeons favor the use of custom laser eye surgery in providing services to their patients. In order to be considered a candidate for wavefront lasik eye surgery, the cornea must be thick enough to handle the procedure with a high degree of the common visual defects.
