Some Facts About Custom LasikCustom Lasik surgery is also recognized as a wavefront technology. Lasik makes use of 3-dimensional measurements of the eye to process images and directs the laser beams to reshape the cornea. With a Wavefront Measurement system, one might be able to see very clearly which is sometimes very difficult to achieve from the common Lasik surgery, eyeglasses or even contact lenses. One must take some guidelines from Food and Drug Administration so that he or she is sure to be considered fully qualified for custom wavefront Lasik system. Custom Lasik measures the ability of the eye to focus on light and after that a 3D map is created which demonstrates all the irregularities in eye. The information in the 3D map helps in shaping up the right kind of treatment for the eye so that the irregularities in the eye can be corrected. The regular prescriptions for eye glasses or the common Lasik surgery can correct ordinary defects like hyperopia, astigmatism and myopia. Other high order problems associated with the eye optical system could not be corrected until the coming of the Wavefront technology employed for custom Lasik surgery. There are some benefits of custom Lasik. This technology is a landmark because this technology has the potential to make the eye vision better, and not only this, it also measures that sharply can any one see. This reduces the risk of complications like the difficulty in seeing something at night or glare, and the defects such as hypermopia , astigmatism and myopia are associated with how much can a person see and are called lowerorder aberrations. They can be corrected with common lasik surgery. If someone who cannot see things sharply it is a part of high order aberrations which include problems like not being able to view things at night or even shadows. This can only be corrected by custom lasik. There are few custom Lasik systems such as Tchnolas 217z, Zypotix Sustem (Bausch and Lomb), Star S4 Active Trak with Custom Vue (Visx). The custom Lasik has various advantages: - It reduces the chances of loosing best corrected vision - It also helps in achieving the greater chances 20/20 vision. - It helps in reducing the chances of losing visual quality or contrast sensitivity. It also helps in reducing the chances of night vision disturbances and glare. Sometimes people complain about the quality of vision, and are sometimes unable to see clearly or see very dim after the common Lasik surgery, but since wavefront Lasik system or custom Lasik is more advanced, as it has no such complications. Custom lasik works with a popular method as it begins with using wavefront device which transmits the safe ray of light in eye, it reflects back into the retina and this device captures all the disorders in the eye are it lower or higher. And all these irregularities are displayed on the 3D map and it is also called as wavefront map and this enables the surgeon to customize the custom lasik as per the requirement. |
