My understanding (and I may be wrong here) is that if you take a traditional PAL design, and freeform it without adjusting the design (which is pretty much what Essilor did with the Comfort and Physio), you will end up with a weaker add.

I've certainly noticed this phenomenon on Comforts when I've focimetered them....

I would also expect the Comfort Advans would be slightly softer than the old Comfort (which has traditionally been very hard), purely because the freeform should widen the intermediate channel, but I don't dispense enough to form a solid opinion.

I think you should do your best to move old Comfort wearers to Zeiss. They will have superior vision as a result. I find they tend to have trouble with Hoya designs though.

The primary difference between the Old and New Comfort was they moved the unbalanced distortion that was prelevent nasally, more to the outside. Despite this small change most patients didn't notice any difference. The main complaints have been a loss of intermediate vision in the New Comfort, and the old Comfort had a terrible intermediate to begin with.

Other questions considered, is a lens that 19 years old still the best lens for your patients? To put in another way, when the Comfort launched Windows 95 was still 2 YEARS in the future. X-Files was in its first year, and Spray on Hair was on an Infomercial near you.
