An outside our office OD has prescribed the following +2.00-2.00x180 add +1.00 with 1prism diopter down OU (yoked) in the distance for a FT bifocal fit mid pupil for a 10 year old girl. For 4 years she has worn distance only glasses.
For those doctors who believe in yoked prism can you help answer the following question that comes to mind with this rx?
The power in the vertical is plano so if I put the distance prism as prescribed I will get 1 down ou distance but through the reading the seg shelf will negate the prism to produce no prism. Would this be what the doctor wants?
Anticipating that the doctor may want prism also in the segment can a lab person tell me if a bicentric grind can be done on this lens? Would an executive with no seg shelf jump work?
Yes I plan to call the Doctor but would like some feedback from you gals and guys first.
Also what does FCOVD mean after the O.D. title?
Please start another thread if you want to argue the merits of yoked prism as I know this was a hot topic a couple years ago! Are you listening drk?:D
Thanks
