Custom Low Vision fitting

So here's another job we did for another #LowVision patient that I thought was a nice example of what we can do here are McCray.  This post is a little longer, but I think it deserves a little more explanation

First of all, the job took a week just to plan the best course of action.  The stock frame that came with the Ocutech was metal and the device was screwed on and custom moulded to fit the metal frame.  We were tasked to mount it to a completely different acetate frame, with a different shape, size, composition and no screw holes to secure.  It was an interesting challenge.

The first thing we did was to flatten the acetate frame's bridge and nose form. The Ocutech need to be secured to a flat surface front and back.  I used sandpaper against a flat block to do the grunt work and a mill saw file (fun fact: also called hand file or my favorite: Blunt, flat, bastard file) to keep the sharp corners.  

Then I had to drill 2 small holds for anchoring and another 2 for the screws to go through.  

Once those were finished I realized the frame was still too thick for the screws to go through and secure the other end of the base.  I was able to sand it down to just under 2mm with the hope that the two flat plates on front and back would strengthen the bridge.  

Once the front and back were secured, I had to reshape the base plate (black plastic base) on the back to allow room for the patient's nose, and also add in a custom set of nose padarms for support. Note that the base plate is in the shape of a tooth with roots exposed as opposed to a rectagular block. 

All in all, I'm pretty happy with the outcome.  =)
