As I’m thinking about how to begin this post, I think back to optometry school and the availability of the diagnostic equipment that was there for us along with the wealth of knowledge of the different doctors and professors there. We pretty much had it all at the University of Houston.
When I started practicing at Vision Source in Kingwood, Texas, we had the opportunity to try virtually any new diagnostic equipment because I worked for the CEO of the nationwide franchise. We tried more products than we ultimately purchased, but we had a great array of diagnostic instruments in that practice too.
Then I found Dr. McMahon at EyeWorks. I think it’s safe to say he’s a bit of a gadget guru like I am and always on the look out for the next best diagnostic instrument to help our patients with their vision.
So I thought I’d write a little about the instruments we have and what I like about them over the next few posts.
In the picture above, you see a printout from our Z-View Aberrometer. In essence, it measures how light focuses through every surface in each eye from the tear film on the surface to the photoreceptors in the back of the eye. And then it quantifies these imperfections in to the printout above. FYI, click on the picture to get a larger version. I’ll explain it in the next post.
Now, stay with me here. I promise not to go in to a highly detailed and overly technical description of this instrument. That’s not my style!
So over the years, all optometrists have performed eye exams on patients who just couldn’t be refracted (the better 1 or 2 test) to a crisp, clear endpoint at 20/20. And when this happens, there are different types of abnormalities to look for from the front to the back of the eye that can be pointed to as the reason…anything from dry eyes to cataracts to macular degeneration. Oh, and my newest emphasis…binocular vision problems.
But what if I don’t find any of these and I still have a patient unsatisfied with their vision correction? In the past, I’d probably end up having them come in for a prescription re-check and ultimately end up saying that’s the best we could do. But the Z-View Aberrometer has changed all of that…
I sense this post getting too long. Stay tuned to learn more about the Z-View aberrometer in the next couple of days…
