2. The Nidek OPD-Scan III
I like to show patients the multicolor axial view of the corneal topography and ask if they see the “bowtie” shape (See Figure 2: The full color axial map on a topographer is a good way to help patients visualize that they have astigmatism), either standing up or lying down.
“That’s your astigmatism, and we can correct most of it,” I explain.
I also like the simulator on this device, which displays a beach scene with a boat. A lay person can see that when astigmatism is corrected, the image is crisp and clear.
When it is not corrected, there is more blur overall, which is especially noticeable on the edges and fine details of the boat.
This is an interactive patient engagement platform that uses auditory, visual, and touch elements to help patients understand their conditions. We have CheckedUp wallboards in most of our exam rooms.
I also utilize the educational videos from Rendia, where astigmatism is explained through easy-to-understand animation software. It can be sent to patients after the visit or shown in the office.
These are all 21st-century methods for showing patients what we mean by astigmatism, and most importantly, what it means for their lifestyle and visual function to correct astigmatism.
