The only issues I've had with auto III are with higher power myopes( -6.00 and up) I've had a few pts complain of reduced distance acuity...looking at the compensation they are sometimes as much as .50 lower than prescribed in the sph. And these are with ones that we just used default measurements so I'm not sure that much compensation is needed?? Other compensated designs I use around those same powers usually show much less decrease. Not quite sure why..other than those powers they perform really well .
