I’ve heard a lot about Wavefront Guided or Optimized LASIK, what exactly is “Wavefront?”

When you need your glasses or contacts prescription updated, your eye doctor would get it by using an instrument called a phoropter. This device has multiple optical powers within it, and your visual errors are found by being asked, “What’s better, number one or number two?” This test to get your prescription is called a refraction. In the past, your prescription or refraction from the phoropter would be used for your laser vision correction treatment. This is referred to as Standard, Conventional or Traditional LASIK. This type of LASIK was primarily performed before the mid 2000’s, although many surgeons still offer this type of technology today.


Wavefront LASIK has taken vision correction to a whole new level by not only measuring for traditional refractive errors like nearsightedness, farsightedness and astigmatism, but also subtle abnormalities such as higher order aberrations, corneal curvature, thickness, etc. The laser corrects each patient with a specific treatment, that’s unique to each individual’s eye. Wavefront guided LASIK can often take a patient’s vision correction a step further over traditional LASIK and can offer sharper overall vision and can reduce glare and halos, thusly improving night vision. If you’re considering LASIK, the first step is to schedule a free educational evaluation with at San Antonio Eye Specialist. We have both wavefront guided and wavefront driven LASIK. With our advanced technology, we’ll help you get the vision you deserve.
