RX:
-3.25 -2.50 x 005
-0.50 -5.00 x005
add +1.75
I wanted to put this patient into a trivex kodak unique but the unique only goes up to a cyl of -4.00.
What would give this patient optimal vision and would work with this rx?
Thanks :)
Best progressive for high cyl?

I checked on www.thelensguru.com and found a couple, the Gradal Individual goes up to a 6 cyl for instance. You might want to bookmark that site on your computer. It can be a life saver!
right.. i actually do use lensguru :)
But i guess i was looking more for opinions on what you guys would use... my general go-to lenses are the unique for high-end, GT2 and physio for mid-level, as well as comfort and other various lenses depending on the situation. However, having a cyl that is beyond the boundaries of the unique in a patient that really doesn't mind paying extra to ensure that they have the best possible vision, i was wondering what other optiboard members would use.
plus, i'm not 100% on some of the lensguru information. For instance on the autograph 1.67 lenses it doesn't specify the maximum cyl... and on the zeiss GT2 lenses it states that the max cyl is 4.00 for all materials except for a CLEAR 1.50 lens... the polarized 1.50 lens, even, is a max cyl of 4.00.
thus... im asking those of you with experience dispensing glasses with similar prescriptions to my patient's. What do you think?
Thanks :)

I have dispensed a few of the Pentax PERFAS 1.67 with good results. The highest cyl I have fit these in was 3.50.
Post your results so we can all learn more.
Hm, I tried calling my lab to ask about the perfas lenses but I guess they don't carry them
alright well i spoke with my lab again and they said (although it contradicts lens guru) that the autograph would work in trivex. So I suppose I'll give the autograph a try.
ps: the patient was formerly in a piccolo polycarb lens (also listed on lensguru as being a max cyl of 4.00?). Hopefully the change in material alone lends itself to better vision, and the fact that the autograph is also shamir somehow lends itself to an easy transition (though hopefully a nice WoW type upgrade in vision).

The Hoya ID is available up to a six cyl, and is atoric.

Does that come in a 72mm blank?:DOriginally Posted by chip anderson
MarcE:
No but it comes with full field clarity, near very thin centrally and edge,
doesn't fog up, doesn't require cleaning while wearing, gives the largest image available, practically no distortion when looking side to side or periperally when looking straight ahead, and the optical center is always in the field of vision.

But does it come with a super-duper hydrophobic/oleophobic AR? :D:D
Can you imagine AR on contacts?

I have had patients ask if photochromic contact lenses were available.
You mean they're not???
Boy, talk about something unworkable.

I am affiliated with Luzerne Optical Laboratories, but you may want to give them a call. They are truly a supermarket of optical goods. They are an Authorized Laboratory for Varilux, Zeiss, Hoya, AO/Sola, Definity, Shamir, Rodenstock, Indo, Polycore, Seiko-Pentax, Signet Armorlite, Vision-Ease, X-Cell, Younger etc. It won't hurt to give them a call

+1 with Robert. The Hoya ID works great with my wife and other high cyls. My wife rejects most of the new lenses she tries. She -3.00/-3.50 x175 +2.25 add.
I think you're overcomplexifying (yep - it's a word) things here.
Those -4.00 cyl "rules" aren't rules. It is merely a recommendation, but lens cut-out is what decides whether or not something is actually possible.
You have about a -5.50 total power at the top of the left lens in this job, just consider it a -5.50 job and pretty much any lens should be able to cut out. Beyond that, just use your standard lens you want.
The tooling required for such a job might have quite a bit of cyl, but the actual curve isn't anything extreme if run on a 2.00 base or something like that. So as long as you pick a frame that isn't huge, you should be fine.

I ahve had moderate success dispensing the Physio 360, using their 1.74 hi- index material, with Crizal Avance, A/R.
James :cheers:
We've had good success with Physio 360
cyl go to 6.00
material up to 1.74
availble in 1.67 Transitions
and yes, even that super duper hydrophobic A/R stuff;)

I too would go first with the Physio 360, but in that RX I would do the 1.60. 1.60 has terrific ABBE value which that patient will need.

YEP, agree, unfortunatelly IMHO high n lenses are sold way too early, because it´s claimed to make "thin" and "light" lenses. However, just for high RX, color fringing is even more an issue for still the same Abbe value, so using 1.67 or up becomes twice bad. It should be restricted to the highest RX if possible.
