Lens Suggestions on -16.00 Cyl

**Christosfer** · 10-03-2008, 03:56 PM

Hi all,
This is why I love this forum. I have a +10.00 -16.00 x084 2.50 add.
What would you suggest for a progressive?
His current is a 1.67 Panamic.
Not surprisingly, very few lenses will cut out at this Rx.

Chip probably has a contact lens for him.

**Jacqui** · 10-03-2008, 04:06 PM

I would keep him in the same thing.

CME4: You bet I do. Actually I fit CL's on stuff like this all the time. The easy stuff seems to stay at the doctor's office or go to the advertising chains.

Geez, that lens sounds like it would look like a Pringle's chip.
I'd keep him in what he has, though I don't like 1.67, more labs know what to do with it.
If you can find someone who can do it in 1.70, that would be better.

Not only would I like to see the finished product (pictures?), but I would like to see the patient's topography. s/p PKP?

I've never come across an RX like this before, I would love to see some pics of the finished product!

Yes. Topography and RGPs. That's my suggestion.

They or maybe one other lab will do it anyway!

**Christosfer** · 10-21-2008, 09:55 PM

Well here is what I ended up doing.
I found out who made his last lenses and had the lab access those records. I have never done that before, but in this case it worked pretty slick. I am trying to keep the BC's as close as possible to the previous lens. I thought that his lenses looked pretty sweet for his Rx!

They were originally done as bi-convex on a 3 base. It looks like they might have to move to 5 base this time.

This is where I wish that these "customizable" progressives had better limitations than a 4.00 cyl. I imagine it will be a while before they can cut 16.00 in any of the latest and greatest progressives.

I also had to restyle him because they couldn't get a blank to cut out at a 50 eye. So I put him in a skaga zyl with adjustable nose pads and about a 45 A. He bought 2 pair.

Simple use a myodisc. Patient can't see beyond 30degrees or so anyway with this much power. So grind a plus edge around bowl to desired edge thickness.

How do you think that would look?

Bye the way, I dispensed one of his pairs today. Looked quite nice and he was very happy. He said it was the best he has seen in 8 years. He does have a hard time reading though. He uses books on tape.

I like that idea, you could use a peripheral curve Rx with negative or opposite torsion to align the major and minor axis of the bowl with the 180 and 090 as well. This would make the bowl more cosmetically appealling as an oval aligned with the datum, or you could use the same amount of cyl and get a circle for the bowl.
