What's about Shamir Autograph vs Hoyalux iD ?

**Win C** · 01-20-2007, 05:41 AM

Hi everyone,
I manage to fit a 2nd pair of ID recently. However, on delievery the result is not satisfactory.

Patient of mine is a myope of about -3.00 and add of +2.50 both eyes.
On delievery of the 1.6 ID lens (14mm corridor lens fitting ht at 19mm) patient complaint that reading is not clear and she has to push the frame very high up the nose in order to see clearly.

there is no problem with the PD, and fitting ht. I also adjusted the pantoscopic tilt but it didn't help.

So I asked her to put on her old glasses (a Shamir Genesis) which has the same dist RX but with a lower add of 2.00 and she said that it;s clearer without having to push the frame high up. There is a 1 prism base up in the right lens.

So i tried putting up the one prism in front of the new Rx but she said there is minimal difference. When I put up an additional +0.50 in front of her new Rx, she said her reading is much clearer without having to push it up her nose.

I have decided to change her lens to a shorter corridor ID rather than increasing the Add.

What do you guys think?

Hi Win!

Well, in my experience as an optician it has seemed to me that higher myopes tend to like the longer corridors in PAL's, but that's not a hard and fast rule. Maybe sending the job back to redo the lenses in the 11mm corridor that the iD comes in willl fix the problem, like you said.

My first iD patient was a higher myope as well and ended up with one of each. She preferred the 14 over the 11 so I sent that one back and had them change it for her. She was fine after that!

I don't know what to tell you about the prism except that I would ask the Dr. why he took her out of it...

Actually I did not find out about the prism in her old glasses until I was trouble shooting what went wrong with the Hoya ID. I am not sure why the prism was there in the old glasses. I have asked her to bring in her other pair of progressives by her previous optometrist to determined if the prism was there accidentally or it was prescribed.

Anyone else would know what could have gone wrong?

We only carry Naturals, a Essilor product with a longer reading corridor and I am trying out the new Life Rx Illumina photocromatics. The reading corridor is compact, and it makes it more difficult when going from the write up table to dispense or repair a pr. I did the Captain Morgan for 2 weeks when I first started wearing PAL's 3 years ago. The only way for me to stop some of the swimming feeling was to prop one foot on a lower shelf and move my head a lot slower. I want HOYA'S now that I have read about them. I have too many non adapts that give up going from lined to PAL'S because they can't handle the distortions. We end up remaking the lens and putting them back into lined bifocals. The improvements made in the lens technology should be used to try and encourage those previous non adapts to try this style PAL's.

This has become my new best friend. I can't find the distortion by looking through the lens anywhere.

Judy, can you give us more information on the Polycore lenses??

I have to ask-is the Rx the same? -is the base curve the same? is the frame the same? What is your pupil size? dim light/bright? L'm getting somewhat contradictory findings depending on the person,. We must differentiate

Rx and add strength. We must all try to document these new lenses and their results. Any way to enter a database of new design progressives and their results?

Did you ever find out about the prism?

Hi are you referring to my case?

The patient just came in to test out the replacement lens . I had changed it to a shorter corridor ID. However, the lab messed up the fitting height. I wanted a fitting ht of 19, the lab edged it out to 17. :angry:

So when the patient tried out the replacement, she needs to push the glasses up her nose (again) in order to see clearly. I have sent it back to get the lens replaced with a fitting height of 19.

Do you reckon a 2mm difference in height will cause the reading to be worse ?

**optigrrl** · 03-26-2007, 07:49 PM

Sure - if they made the seg too low then the pt. has to travel that much further down the lens to get to the add. I mean, 2mm is alot when you consider that the average person's eyes drop about 5mm from distance viewing position to reading viewing position.

**cathy** · 03-27-2007, 08:09 AM

I agree 2 mm is a lot when talking progressive lenses. I call it taping the paper to the ceiling. If segs are incorrect then the patient walks around with lockjaw to correct a too high seg and they feel like taping the paper to the ceiling would be more effective than holding the glasses up higher. Even in lined lens, seg placement is as important as location is to real estate.
