Hi, my name is Chris and I would like to know if anyone here has any experience in free-form PAL fitting, neutralizing, edging, and dispensing; that is, are there differences in how they are worked with?

I have heard that there is a device that the patient is tested/measured with to take into account the higher order optical anomalies that FF's correct and for a customized fit. Has anyone worked with one of these and how much do they cost? If it is expensive, is the cost shared with the lens manufacturer?

Any information would be gratefully received. I believe that FF's are the way of the future but we are now in its incipient stages so hard data seems to be difficult to come by. Thanks. - Chris
