Wavefront Lasik Technology

In the past eye examination performed by sitting in a chair and looked through a device that would frighten most children, then declared "better" or "worse" Optometrist until satisfied. This method is acceptable in most circumstances, but because of the subjective nature of the test, can be prescribed accurately. This type of test can not detect other conditions that may exist as well.

Progress in the field of eye surgery has brought new methods of Wavefront eye examination. With Wavefront all "better" and "bad" will be known accurately, and this technology can diagnose a wider range of conditions. The best part right now is that this technology can be applied to apsien glasses and eye surgery.

Wavefront examination is to test a source of light bouncing off the back of your eye (retina) and generate an examination of data derived from light that has been entered in your eyes. The test is very simple, does not require subjective input, and almost immediately results can be known. More accurate is guaranteed with this method, and more conditions can be improved from this map.

As stated earlier, this technology can be applied to lenses, here's how. In the optical laser surgery, such as Lasik, an examination of data by wavefront used to guide and optimize the laser that creates custom surface of the eye (the cornea) to achieve the best possible focus. Now manufacturers use the same precision to fix common problems such as nearsightedness, farsightedness, and astigmatism along with the conditions of higher order.

Wavefront lens type is advertised to be a way to achieve crisper, clearer than a conventional lens type in use for this, but may not be covered by insurance policies. These lenses generally cost 25% - 35% more expensive than conventional lenses, depending on the lens you choose.

With the additional benefits of wavefront mapping, lens companies have started using digital correction on both sides of the lens. This type of correction allows for better precision in the manufacturing process produces a more suitable lens for the wearer. Additional benefits of wavefront technology is being developed. The DOD provided $ 3.5 million dollars for PixelOptics Inc. for the development of an adaptive lens system called the Control lens.

Given this progress, many companies have started to investigate this technology and now produce it after wavefront-inspired lens. One company, iZon, producing a special lens that requires a special machine that creates optical fingerprint for each eye.

Other companies that use this technology without the need for wavefront analysis: Varilux (Essilor America) Carl Zeiss Vision, Shamir Insight, Hoya Lens of America, Seiko / Pentax, and Signet / Armorlite.
