Wavefront Technology is the Wave of the Future - Smart Vision Labs

Originally developed for use in LASIK surgery, wavefront technology is proving itself valuable in other areas of telemedicine. Specifically, it can be used as an alternative to a traditional vision exam.

What happens when wavefront tech is used for a vision exam? For the person experiencing it, it is just a light that shines into their eyes. But what the light is really doing is why it may be the future of vision exams, replacing the eye chart and refractor, (the machine they place in front of your face which contains many different lenses of varying strengths).

After the waves of light go into the eye, some bounce back through the pupil. Wavefront analyzer software measures these waves and creates an image showing how the light traveled in the eye. When the rays bounce back and show imperfections, the images are called aberrations. These are translated into a formula which shows the correction necessary for that eye.

Wavefront technology allows the results of a vision exam to be objective, rather than subjective. For example, most people can picture themselves sitting in their eye doctor’s office and looking through the refractor at an eye chart. The doctor asks, “Which looks better? One or two?” They flip a switch, a new lens comes into place, and the eye chart on the wall looks either clearer or blurrier.

Maybe the first few answers are even really obvious. But what should you say when they really do look the same? Do you just pick one? Do you say they look the same? But what if they are different and you just can’t tell? You are there for an exam, after all. Most people who have had a traditional vision exam can relate to this train of thought.

Using wavefront technology for vision exams takes the guesswork out of the picture for the patient. The light that shines into the person’s eyes creates a reading which shows the precise anatomy of that eye, if it has any abnormalities, and what exactly they are. An ophthalmologist can read this and create a more accurate prescription if that person needs vision correction.

The accuracy of wavefront technology is why it was developed for use in LASIK surgery. When a person is taking a traditional vision test by looking at an eye chart and choosing between “one or two,” a slight bit of human error doesn’t make for a radical change in the prescription. However, the tiniest difference in measurement for LASIK procedures absolutely does. LASIK procedures using wavefront technology are able to use this precise reading and translate it into a very accurate result.

In a vision exam, this is useful because the accuracy combines with the simplicity of the test and creates peace of mind for people taking it. Using wavefront technology for the vision exam says good-bye to the guesswork. The way the light enters the eye and the shape it creates can be accurately measured. The patient doesn’t have to answer (or guess the answer) to any questions. Because the technology takes human error out of the equation, it can produce more accurate results in a vision exam.
