orb and wave scan

Postby susiek420 » Thu Jul 31, 2008 10:39 pm

I know at the second dr. i had 2 different scans, an orb scan and a wave scan. What is the difference between the 2, and which one determines if your eye is symmetrical?

I was out of my contacts for 2 full weeks before i went to the first doctor, but inbetwee consultation 1 and 2, i did wear my contacts for 2 days, not thinking that it would really be a big deal, perhaps that is what did it. I wore my contacts for a few hours 3 days before the second scan. Now i will definitely leave them out!!! I was a bad girl, i just gave in to temptation and put them in to go running

Thank so much for all of your help so far, you are wonderful!

The two devices measure two very different elements of vision optics and eye health. They are complimentary, but not the same.

The orbscan is a topographical map of the front and back surfaces of the cornea. The wavefront scan evaluates the optics of the eye by sending a light source in and measuring the changes when it is reflected out. See wavefront for more details.
