What Is Wavefront Lasik Eye Surgery?Wavefront Lasik eye surgery compared to conventional laser eye surgery results in better vision for some patients. However wavefront Lasik eye surgery may not be the best choice for every patient depending on factors that should be determined by a competent eye surgeon. Wavefront Lasik eye surgery differs from older more conventional methods of eye surgery in that wavefront Lasik eye surgery is done by a mapping system that guides the laser during the surgery. The "mapping" system of wavefront Lasik eye surgery is used also to diagnose and determine the extent of the refractive error present in a patient's eye. When wavefront technology is used for diagnosis, light is sent into the eye in a specific "grid" pattern, and then measured after it has passed through cornea and onto the lens of the eye. When there is a difference between the light that is sent into the eye and what is measured is considered a refractive error. The position of these refractive errors are then "mapped" or plotted into a computer system and provide a more accurate laser eye surgery experience. Since patients eyes are continually making very fine jumping movements that are beyond his control, the tracking system of the wavefront Lasik technique assists the surgeon by scanning the eye thousands of times per second. Then, sending the data back to a computer, the computer makes micro-adjustments to the laser at speeds many times per second to reposition the pinpoint it between pulses of light, tracking even the most minute movements of your eye during treatment. Before wavefront Lasik eye surgery these eye movements were not able to be tracked by the surgeon as they are too small and too quick. Wavefront Lasik eye surgery is revolutionary also due to the fact that it has the potential to improve not only how much you can see, but also improve the way a patient views contrasts and fine details. Wavefront Lasik eye surgery is said to reduce the risk of glare, halos, and difficulty with night vision following surgery. This seems to be some source of debate however. Some eye surgeons argue that the use of lasers to correct vision causes additional refractive errors in the eye but most eye surgeons agree that this advanced method far out performs conventional laser eye surgery techniques. A patient must meet certain guidelines for wavefront Lasik eye surgery treatment to be preformed. The eye must be healthy, the patient must be an adult, a patient's eye glass prescription must be within certain limits, a patient may not be pregnant, and the patient may not have a degenerative eye disease. Also be aware that wavefront Lasik eye surgery may not be ideal for those with "thin" corneas but that overall the wavefront Lasik eye surgery technique is the most accurate available. |
