Lasik Surgery Information – A comprehensive review of Lasik Brand New Wavefront Technology
Lasik surgery is designed to correct the vision of his patients. The most important part is the correlation between patient information and LASIK visual system. The groundwater model by cutting the cornea of patients was designed to meet the needs of patients' needs. This new technology is the best technique for bringing together this important information.
The introduction of wavefront technology
Wavefront is a technology whose goal is to provide a goodDegree of refraction in different parts of our eyes as the light source passes through it. The process outputs a map of artifacts, which acts as a fingerprint of the eye of the patient 'because of the uniqueness of the patient.
Refraction on the cornea can be affected by some conditions in terms. For example, higher-order aberrations were always astigmatism are related. A correction of these aberrations surely improve the outcome of the operation. The results as an improvement factor20/20 can be achieved. Wavelength technology reduces the chance of losing best corrected visual acuity or visual quality as well as night vision devices. Indeed, clinical studies have clearly shown that about 80% of patients had a Lasik 20/20 Vision.
In addition, wavefront technology used to identify good candidates for Lasik surgery. Poor candidate for Lasik, surgery may reduce the existing visual damage.
Wavefront Technology Applications
There are two types ofCorneal abnormalities, cylindrical and spherical. Astigmatism is an abnormality of the cylinder while the short-sightedness (myopia) and farsightedness (hyperopia also be caused) is caused by both spherical anomaly.
Wavefront technology when used correctly can be endless show many anomalies. This is done through the use of a solid target with a laser beam input. This produces the light beam, which in turn is a wavefront sensor in the preparation of the slope of the targetWavefront as it exits. The special software works then the properties of excimer laser ablation.
The visual target company is then used to help the patient maintain the correct view is calculated during the measurement. The laser light in the eye of the patient if he fixed.
If the laser beam is in the eye, it generates a wave front with a flat surface. With an impeccable eye, reflect an undistorted wavefront is back. In practice, this beam of light travelsthrough an imperfect lens. The light passes through a distorted cornea and other parts of the eye. The combination of all these is the wave front, has a large amount of data to get distorted get to find out the exact shape of the cornea. The wavefront is used to detect abnormalities associated with the eye to turn the cornea.
At the beginning of wavefront technology
Wavefront technology was created for a very long timeand is to help today, used the right eye of man. Astronomers have been pioneers in the use of this technology especially for the improvement of vision in their telescope equipment for similar purposes. Once the mirror is distorted to reflect responsible, can be optimized with the available data. These records are also used to get rid of anomalies, such as our atmosphere. And 'the analogy between this method and what about our eyes.
The various options of the wavefrontTechnology
In the U.S., there are basically three service providers to wavefront CustomVue (VISX S4 laser), CustomCornea (Alcon LADARVision laser) and Zyoptix (Bausch & Lomb 217z Technolas laser). Each manufacturer can make a recipe suitable for a particular patient.
Wavefront technology is a new technology to create precise and unique recipes for Lasik surgery patients. With this technology, LASIK patients experience more frequentsuccessful operation.
