Opinions of fitting @ 17mm

[Chris Ryser]

I would use the short corr.
As far as salesmanship, the patient wants the frame they want and as Opticians we should be able to find a lens to suit their needs.

How valid would be above statement reversed ???

The optician is the specialist who knows that certain frames will not give a total performance and educate the patient to the fact that he will not have a full reading area.

If you are 8 feet tall you dont buy a mattress that is 6 feet long.......and maybe you do.

In the middle ages women in China got their toes bent down and taped under the foot sole because they had smaller feet but could not walk properly all their life. It was done as children and they had no choice.

If your client is not used intermediate zone .... used short corridor
if he need intermediate zone ... used standard corridor. and change frame.
you can tell to your client about intermediate zone.
The client will change the frame if he need intermediate (computer use)
and beleive the specialist.

perfect fitting for FH 17 mm. .... should used PALs that have corridor 11
if you used PALs corridor 13 the readind zone is decease from 100% to 70% ... the patient may be complain about reading.

if you used varilux physio that it PALs corridor 14.
that should fitting at 20 mm. for perfect fitting.

if you fit it 17 mm .... it is minimum fitting for this lens. may be have reading complain.

I never fit physio at 17 mm.
I feel ... the user will receive PALs that have less than 80% of money value that he pay.

I'll let you know in about a week. I'm wearing an Ellipse at 17 and am about to order a Physio at 17. My add is 2.00 with dist of 3.00. I have had no issues with the Ellipse but I want to try the Physio so I can tell my patients that indeed one is better than the other (if it truely is). I still like to peek underneath the lens when inserting screws and doing my cuticles so do not want a deep lens.

So have you gotten your Physio lenses? Can you share your experiences with them? By the way, is your distance -3.00 or +3.00?

I usually don't fit the Physio at 17. At that height my favorite lens is the Definity Short. If someone needs a cheaper lens I often use the Ovation.

How are they different, besides price?

Per HappyLady's request.

Recieved my Physio glasses on Monday. Coming out of an Ellipse 360 Hi Index at 17mm into the Physio Hi Index at 17mm. Frames are similar and have the same B. No change in Rx which is -3.00 sph ou w/ 2.00 add. I have spent the last few days comparing the two. The Physio is wider in the distance and midrange areas and easier for driving. I think I like that the best. The reading area is not noticeably wider at all. To be honest I think the Ellipse worked better at 17mm than the Physio for near. But the tradeoff is the wider distance.
My conclusion? I won't fit the Physio below 18.

Well, I've never worn the Ovation so I can't speak from personal experience. It seems to be a very balanced lens and patients like it. I can't remember the last time I had a non adapt in it. I have a friend who I fit with both and she liked the Ovation just as much as the Definity Short.

What I don't like about it is that it is the lens that Costco uses. :(

I would think that all these min seg hts are not good to fit with

Is it not true - that at the min seg ht suggested -[ the pt is only getting 85 % of their add power?

So would it not be better to go into a shorter fitting design - so they might get their whole add ?

I think that is why - we still see some docs - bump the add by a 1/4 - since they know most folks will use the min seg hts - allowed per design - instead - of changing it or adjusting it - ?

Before the advent of short corridor lenses it was common to "bump the add" (whether by the doc or by the optician) to accomodate a lower seg height. Really no need to do that now when you have lenses that accomodate for you.

fit short corr Ellipse, never face problem.
i never fit 17mm height with physio 360.

Im just trying to "keep up" with this thread. :D

Has anyone had success with using disimilar progressives to solve vertical imbalance. Comfort and small fit for example. Patient just had cataract surgery. OD -2.50+.75X155 +2.25 add OS +.25 sph and +2.50 add. Should we throw in i/2 diopter BU to boot?
