Great question!!!!
From what I can tell…Ford’s Egypt Eye, was Jeff Ford’s attempt to take on a challenge presented by Fred VanSant on page 16-18 of the March 2000 USFG Newsletter. You can download that newsletter from the USFG website Library. VanSant’s re-design of the Pharoh’s Eye might provide you with the answers you are looking for.
I am also going to attach my attempt at a re-design, which might also shed some light on your efforts.
However, I believe the design was meant to be freewheeled, such that the eyeball gets curved, or “scaloped”. This design is certainly up for interpretation, and that is what Fred VanSant concluded.
Enjoy, and let me know if you want more details.
