A LASIK procedure starts with a measurement of the eye’s ability to focus light rays being taken. In order to obtain this measurement, an eye surgeon will send a safe ray of light into the eye using a wavefront device. The light hits the retina and is reflected back through the pupil, into the device, which then gives an accurate measurement of how well the eye is able to focus light rays.

From this measurement, the wavefront technology will create a 3D map that shows what problems the eye is having in processing images. From these images, the map will guide the laser into reshaping the cornea in order to correct its imperfections. LASIK eye surgery is extremely precise and allows for the correction of many vision problems that eyeglasses or contact lenses would never be able to correct.

Wavefront technology is not only credited for helping how well people see, but also how much they see. This means that it not only helps you achieve 20/20 vision, but also helps with things such as contract clarity, and the actual quality of your sight.

Having your quality of vision is an obvious benefit, but being able to pick up these elements of vision also reduces the risk of other LASIK surgeries such as glare, the halo effect, and difficulty with night vision.

One of the biggest drawbacks to LASIK surgery is that it’s quite expensive. This isn’t just because it’s a custom surgery that uses the latest technology, but also because all eye surgeons need to pay a royalty fee to the manufacturer of the device every time they use it.
