Hey guys, I am an Osteopathic student and was interested in doing some experiements with Osteopathic manipulation and refraction/lens prescriptions. What do you guys recommend as far as a good book on the art of refraction and also, if I were going to look for a trial lens set, what kind of stuff should I be looking for?


Thanks!
 
This book is good for refraction:

http://store.medrounds.org/shop.php?k=prescribing+glasses&mode=Books

The Fine Art of Prescribing Glasses Without Making a Spectacle of Yourself

Book Description
Award-winning text can help every clinician -- beginning and experienced --have more satisfied patients. Through 150 case studies, the book helps you solve everyday problems in refraction. It explores and explains the multitude of variables that can lead to patient complaints, giving logical answers to many different kinds of situations. The result will be more wise decisions in diagnosis and prescribing. Best Medical Book of the Year award (American Medical Writers Assn.).
 
I'll have to check that one out, Andrew! 🙂

The one they always told us about in class was: Borish's Clinical Refraction

Although, I'm unsure how good it is since I could never muster up the 173 dollars it cost! 😱!!
 
CPW, $173! This is the problem with academic publishing. Higher costs and the authors get nothing: http://www.medrounds.org/blog/2005/06/crisis-in-academic-publishing-and.html

Why don't some of the ODs here get together and write a guide on refraction? Dr. Hom? CPW?

I'll publish and distribute the book at a much, much lower cost to students while giving the authors more for their contributions.

We got Borish last year...I haven't opened it much and from what I've gathered, not many people do. I wouldn't recommend it.

Since you are a DO Osteopathic student maybe Kraskin's work may be your style. Talks about posture and refraction with lenses. Just for reading.
I'd go with Dr. Doan's advise as first choice for your actual experiments. You'll have fun! Try YOKED Prisms. 😀
 
And what about a trial lens set? What do I need in one of those? Any recommendations on brand, where to buy, cost, what lenses to include, etc?

Thanks!

Can you outline the details of your project or thesis? A full trial lens set can be very expensive.

Buy one on eBay! http://cgi.ebay.com/Trial-Lens-Set-...ryZ31466QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Costs run high. Can be about $200-$300 range.
Ebay might be your cheapest option. Lenses are about the same regardless of brand. Most popular are Marco, Burton.
In the case you need:
Plus Lenses from +0.25 to +20.00 Diopters
Minus Lenses from -0.25 to -20.00
Cylinders (to correct Astigmatism)
- cylinders are what ODs use
+ cylinders are what MDs use
Now you can find MDs using -cyls and ODs using +cyls depending in what clinic they work at. Just get one type of cyls, you can always transpose later if you need to. Buying both the + & - cyls would be a waste of money.
You can get Prisms, Occluders, Pinholes at the least to fit into the the trial frames (sometimes the frames come separate so make sure you ask if they are included).

these sites might be to your interest for your paper.

that's a cheap one if it's only 300 dollars. the ones they made us buy in school were 850 dollars !
 
:wow:

Dear DOSouthpaw,

Is there a chance that you could describe your research design? If you were interested in making this a blind study, you could have a second person do the refraction and thereby make this a bit more rigorous study design.

Thanks guys for all of the great info!!

Just so you know, I don't have a research design per say. I'm just doing some experients on myself and a few of my friends right now. Someone posted a link to an Osteopathic site that is similar to what I'm doing. Basically I'm going to see if I can use glasses as a cranial "orthotic" so to speak.

One of our professors at school started having this done by a doc up in New England. When he first started he was in trifocals with horrible astigmatism. Now a couple of years later after doing this he is down to a plain lens with no astigmatism at all. Very wierd stuff.

If I can figure some of this stuff out I'd love to go on to do a pilot study and then something bigger. When I get to that point I'd love ask you guys for help, I mean heck, people think we're eye doctors all the time anyway. I'd love to have a nickel for evertime I've been called an optomitrist. Even our anatomy professor thought that's what we were... pretty bad because I had to know what a DO was to get in the school and pay to be there, you'd think the same standard would apply for people that they pay to be there. lol

Hi, Yes, New England is known to have these types of optometrists. If you are in kentucky, you may find some of these kind of docs too. If you look up optometrists, look for a fellow in the following. FNORA, FCOVD, FOEP. These ODs may be doing what you're attempting to do and maybe one might let you shadow and give you more ideas. bye 🙂
 
How are these kind of optometrists viewed in the general OD community? From what I read on here it seems you all are quite open to the more unusual stuff, which is cool. I know in my DO relm, it's seen as quite quacky and in the MD relm...well you know. lol

Yes, it's true some seem quacky, :laugh: I still have a hard time differentiating who is quacky and who is not when it comes to these subject matters myself. People ahead of me tell me you eventually develop an eye to differentiate who is who. You may want to stick to an academic professor from any of the 19 OD schools or somebody that the binocular vision department recommends in your area if you ever want to partner up with one of them.
There are some guidelines you should follow if you pursuit this yourself. It might be responsable to at least inquire about this. You may cause someone "horror fusions" (causes the patient double vision they didn't have before) :scared: :scared: if you don't apply it properly.
I know DOs that hire OTs (certified orthoptic technicians) to do their physical therapy with the visual system included. That might be your style since you are looking into this. I think some physical therapist programs train their PA's to include the visual system too, with yoked prisms, or convergence excersises, that would be ideal since, for example, Stroke Patients and Trauma Brain Injury patients have visual problems along with their other physical problems. Whatever didn't get corrected with eye excersises gets corrected with prisms on their Rx. That is a delicate measurement, you don't want to put too much prism.
If you're still in the DO/MD relm of course they will think its quackery. they havent been educated in the subject matter yet. You might want to go to the ophthalmology forums, you'll be surprised how many OMDs chat about developmental ophthalmology, behavioral ophthalmology, neuro-ohthalmology. All these sub sub specialists have seen the light and truly see what's happening in the brain related with binocular vision.
This is a hard subject to tackle, Good Luck. 👍

Here is a recently published guide for refraction by Todd Zarwell, OD.

It is OUTSTANDING!
