I looking to buy a new pupilometer. Can anyone please explain the difference between types A, B, C or D pupilometer. I also see on ebay type TJY-01. Any advice. :hammer:

all the same. Get the one that looks coolest.

And double check your readings with a good Ol' fashioned PD stick. I like the plastic ones but you can get metal and even wood!:bbg:

Some use internal prisms to simulate the working distance. These measure the true convergence of the near PD, others use formulas to convert the measurement to the near PD. If you had a choice I would recommend measureing the actual near PD at the simulated working distance rather than relying on the computation of the near pd.
The best pupilometers seem to be the essilor. I've had problems with the grey market ones.
Calibrated refurbished used ones can be bought from the essilor equipment repair center somewhere in the Midwest.

Don't waste your money on a pupilometer, Digital centration is the wave of the future, save your money and but a system that takes digital centration. Digital centration will replace the pupilometer just as the pupilometer replaced the PD ruler 15 years ago but then again you will see some old timers that will never progress and still use a PD stick which was from the time of the ultex era.
I'm all for digital centration. But...don't get rid of that pupilometer just yet...

The only TRUELY accurate measure of "PD" would be a subjective measurement, Taken over the RX involved, a la DESIGNS FOR VISION.
Still waiting for this to come to Rx eyewear instead of just bioptics.

After 2012, believe me, they will again!

Digital centration is where a picture is taken from a patient with the glasses that are to be measured and Pupillary and vertical placements are accurately derived from and exactly marking and measured. This is the way many optical measure in Europe and Canada and will be the standard way throughout the world in the very near future.
Technology is great but it can't replace an optician. Digital autolensometers are a very good example of that. A good optician with a junk pupilometer is better than a digital centration robot or whatever it is.

Sherman, set the wayback machine.
I got my PD stick and a penlight.
Digital centration will not replace opticians but it will makes opticians better and the product they sell more accurate. Similar to the auto refractor or the patternless edgers, they only help to produce better results or better product. Technology can help and being progressive only can make you better in what you do. Optician that still using PD sticks for measuring progressive are examples of why this field never progressed as it should have over the past 20 years. PD stick were accurate enough for single vision and bifocals before the pupilometer became available but when new products and technology becomes available we should use it if it help us be better at what we do.
They're not all the same! I've got a bunch that Essilor sent me that have batteries in them from 1998, while the one I bought from a company at VEW just sucks the life out of the batteries in about 5 days.
They are NOT all the same.
(BTW, I've got a deal on a pupilometer if you're looking for one.)

DO NOT USE CHEAP PUPILOMETERS. I worked in a very large practice with a progressive remake average of over 40%! Yikes. I tested all 6 of our pupilometers and got 6 different readings. Changed the pupilometers and the remake percentage dropped in half over night.
Use only the best, test them out against a constant (I use my own PD) as well. Even good puplimoters need to be recalibrated.
If you have Essilor or Zeis points, you can redeem those for puplimometers that don't cost you any $. Contact your reps before you buy, I have not paid for a pupilometer in many many years (except when starting a new office).

Okay, I agree they're not all the same. But a good optician will know the pupillometer is junk and double check it with a ruler.

The pupilometer is great for image. It may be fluff, but looks high-tech.
We make a big deal about sitting a patient down and adjusting newly bought glasses and going ooh and aah.
Same needs to be done with the initial measurements. Patient needs perceived value, not some outdated guy with a slide rule.
And then "double check" with a ruler in case the pd computer made a mistake.
Can't print out a pupilometer on-line to get your pd for the on-line specs.
