Custom Vue or Wavefront Guided LASIK is LASIK surgery with the addition of special measurements taken of the eye and used to guide the re-shaping of the cornea.
Your Unique Eye
Each person’s vision eye or vision is unique, just like your fingerprint or DNA. Wavefront measurements provide the doctor with a map of your vision similar to a geographic topographical map with the shapes of the mountains and valleys. Everyone has aberrations or irregularities in their eyes or vision. No one has a perfect eye or vision. The wavefront equipment measures those aberrations that can be used during the surgery.
Wavefront equipment projects a light into the eye and then measures the light reflex that reflects back out of the eye. This is just like what you see in some photos of people with red pupils with flash photography. The computer in the equipment then evaluates this light wave and develops a report of the eye’s shape related to the aberrations found in the light wave reflex. This information is placed into the computer in the laser to guide the surgery and reduce the aberrations.
Types of Procedures Used with Wavefront Surgery
Wavefront guided laser surgery can be used with any of the laser procedures; L ASIK, LASEK, PRK, Epi-LASIK and Intra LASIK.
Advantages of Wavefront Guided Custom LASIK
One of the advantages is that it not only can improve how you see as testing the vision with an eye chart but also can improve the quality of how you see as measured by contrast sensitivity. Contrast sensitivity measurements are done by seeing images or letters on a chart that are not black letters on a white background but various degrees of grey letters on a gray background. Fewer aberrations mean less glare, halos, or night vision problems such as driving at night. Most doctors are using wavefront guided laser procedures due to these advantages.
