I fit a pt who was +1.00 OD and -2.00 with some cyl OS as a first time wearer, 2.25 add. She picked up saturday, and other than some double vision from the 3 diopter imbalance, she loved it. She saw no distortion at all. So, I am thus far pretty pleased with the lens. I have enjoyed Varilux products, and, yeah, of course they have marketing hype. Everyone who is trying to sell something does. What matters is how our patients see. :)
Jennilou, Just out of curiosity, which version did you sell? The Design, Fit, or 4D?
The ipseo was actually a revolutionary design incorporating patients specific "gain" values into the lens design. The Ipseo used a ratio dubbed the gain which was the proportion of the eye rotation to head rotation to customize the design for the way that particular patient woud use his/her PALs. The HOYA mystyle now incorporates this type of data into their design as well, but uses a type of questionaire rather than a scientifically calculated value to accomplish the same thing.
I'm not a big E fan but I have to give credit where credit is due, they took a left when everyone else took a right. With great risk comes great reward and they have benefitted with many rewards over the years.
Also using a more customized horizontal optical modulation is a step ahead of other designs, we'll see that creeping into designs in the future and all of a sudden you won't be able to order a single lens without providing the other prescription. Currently we provide our labs with an Rx for the other eye when ordering one pair and that data is so that they can choose the proper base curves and incorporate the proper prism thinning.
Interesting analysis, thank you.
So I guess that the image matching doesn't work if she is seeing double.
I'm not an OD, but I would blame that on the 3 diopter imbalance. Esp since it was getting better as she wore them
For sure its the imbalance, even a 0.75D imbalance in the vertical meridian can lead to discomfort, My question is how can she read in the presence of diplopia? Does she close an eye? Take them off? And how long does it take to regain single vision. At least my initial fears that they have duplicated my work and patent pending method have been lessened (because it is possible to reduce the dynamic magnification (prismatic effect) without slab off prism and mitigate the diplopia.)

Its a lofty claim, I can attest that the only lens company actually doing this is SHAW lens, we create iseikonic (equal image size) and isophoric (reduced prismatic effect) lenses for the mitigation of image difference with anisometropia. Souns like Essilor copied our marketing material.
We've dispensed a few of them so far, and patient response has been positive across the board - if not astounded. All were relatively low myopes, low adds and no large edge to edge demands from work environment or day to day use that were alluded to in lifestyle questioning. We haven't had any super wow moments with the first ones so far, but I believe it's far too early to draw any definitive conclusions yet.
Slab? did you say slab? Oh my such old technology. I have one slab in process right now and that is because it belongs to the husband of our OD. (dont want to rock the boat there)
Cannot remember the last slab I ordered. Something like that comes up I simply request the lab to reverse the base curves of the lens. If Rx power calles for a 4 base on the right and a 6 base on the left reverse them. Use the 6 base on the power for the right and the 4 base on the left lens power. Have yet to see it NOT work for the patient.
You then have no added expense of a slab and no slab line. But the boys in the lab lose bragging rights as to how pretty the slab would look if they did it.
Marketing! Said it for years. Essilors the one laughing all the way to the Bank.
All three were the fit as we don't have the camera/computer in office currently. I heard back from our second patient yesterday after a couple weeks in her lenses. She's an active outdoor type who's all over the mountain and canyons in both summer and winter. She says she's noticed a "smoother" field of vision overall, and her periphery is noticeably more comfortable than two previous PALs. One was a first generation Physio, the other was a local chains 'house' brand. At any rate, the feedback continues to be positive so far.
Our Essilor regional rep-guy came in this week to show me the new Varilux S lenses. Like a lot of you on this forum, I was VERY skeptical, and assumed much of the lens would be "marketing based". I have to say I AM IMPRESSED. I was shown an uncut lens blank, 4 base, (lens was not surfaced yet). There is LITTLE to NO swim AT ALL- the lens is seamless down through the reading area at the bottom, as well.
I am eager to actually fit one of our patients in this lens and see what they think. It is true that the 4D version is only compatible for use with the VISIOFFICE tool, but the other styles can be fitted by taking panto/wrap/vertex measurements like many of the enhanced-fit digital progressives. Varilux S is also TRUE DIGITAL- both sides of the lens are digitally generated to precisely match PD, etc.
I cannot tell you how impressive I found this technology. I began my Optical career as a lab technician, and I am familiar with many different brands and styles of PAL lenses out there... nothing I have see thus far has EVER come close to how CRISPY CLEAR these Varilux S fancy pants lenses are!! I am anxious to hear what other dispensing Opticians think after they have actually fitted someone in this new Essilor product. We will see how much of this is HYPE and how much of what Essilor claims is really true!
=D
I could not agree more, thanks for the realistic viewpoint.
Oops, did not reply with quote- apologies. I appreciate the feedback from those of you who listen to their patient's feedback, rather than getting stuck on marketing, technical details, etc.
Thank you!

Tried a comparison between the Varilux S Design series lens and the Seiko Surmount for myself. Both the same Rx. I did not see too much of a difference between the two although the "S" was a little clearer in the extreme periphery. Seeing that I have been dispensing free form lenses for about 2 1/2 years, I cannot take the chance that I would have a patient pay $150 more for this lens and not see a true benefit from it going into this from a good free form lens. Now, the "4D" may be better but, with my location, I need to wait for the price to come down.
Rx: +0.25 -1.00 x50
-0.50 -1.25 x125
Add: +2.25
