(I was not asking about how much worse the myopes got. I was asking about the percentage of the myopes in your office whose myopia does not get worse. Mike Tyner's answer is zero which means none of the myopes in his office whose myopia does not get worse.)

I don't regard myself as being a dogmatic person, and if such a method was presented and backed by sound science, then I would embrace it.
But, I happen to believe that we are indeed on the cusp of having such a method(s), and I think that this is a great time to be an optometrist.

Just to confirm, what is the success rate for myopia control in your office?
What would you do if you know of a myopia control method that really works?

Because no "myopia treatment" successfully reduces axial length. Decreases in myopia are more likely from relaxing accommodation, not reducing axial length.

I know that accommodative spasm is common and notoriously variable in the young population you described.
I know that attempts to reduce or retard axial myopia with lenses and exercises have failed, as compared to controls.
And I know that a collection of anecdotes cannot outweigh statistical comparisons between treated and untreated groups.

From childhood to about age 40, my refraction changed from pl-025x090 to pl-100x090 OU and I wore no correction.
I got glasses around age 40, and I've worn them fulltime now for 12 years, and it's still pl-100x090. If you rely on my example, you'd have to conclude that astigmatism increases when uncorrected, and stabilizes once you begin wearing glasses.
Such is the treachery of anecdotes.

Western journals don't contain any "myopia control" techniques that work for axial myopia, except topical muscarinics.
Please tell us if you've seen successful comparisons between treated and untreated groups.

> The results were astonishing. I've seen astigmatism get better. I've seen it get worse. I wouldn't trust my own experience, other than to say small increases and decreases are common. Looking it up I find astigmatism doesn't respond to spectacle correction appreciably, either way. That's just what the textbooks say, not me.
I've had my own diopter of cyl, uncorrected for decades, and it never went away. Why didn't it?

My impression is that you've seen your most "astonishing" results among a population who are notoriously variable on tests like the Jackson Cross Cylinder. Were there objective measurements that changed (retinoscopy, autorefractor, keratometry), or was the JCC your only instrument?

And that JCC results can be skewed dramatically by changing the instructions just a little, or by using different targets.
I would point out that minor astigmatism (050) is normally variable, subject to patient responses and measurement techniques, before considering hydration, hormones, nocturnal exposure, and habitual lid position.

My conclusion is you might change the shape of your ear cartilage by keeping it bent a certain way, but you won't change it by hanging a piece of clear plastic out in front of it.

Dear William Stacy, DrG, Mike Tyner, p.clarkii, Dan Abel, fellow optometrists, and all truth seekers:
Thank you all for your compliments and for being polite.
Dear Mike,
Mike Tyner wrote:

This way your astigmatism could be reduced to its [quoted text clipped - 4 lines] > > -MT This was also what I thought when I first started practising optometry in Asia years ago. I knew nearsightedness can be reduced or cured if it is not too severe, but I didn't know if the same theory applies to astigmatism. I had only read it somewhere that astigmatism should not be corrected and somewhere else that it could be reduced with a special lens. I didn't know if it is true since I had never seen it.
Nevertheless, I gave it a try on my patients, since I am a seeker of truth. I wanted to see for myself whether or not astigmatism could be reduced or completely cured.
The results were astonishing.
One of my first few patients, an elementary school teacher's daughter, an 8-year-old girl, had pretty high astigmatism when she first came to see me. Her astigmatism was -2.50D. I gave her a pair of special glasses to wear and asked her to come back a few weeks later.
Six weeks later, her astigmatism was down to -0.50D.
Another early patient, a 15-year-old girl (a high school student), was at -3.50D sph. -0.50D cyl. Three weeks later, it went down to -3.00D sph. PL (0.00) cyl. Her astigmatism disappeared.
>From then on, I knew that astigmatism does change and that it can be reduced or cured if treated properly.
Some more recent cases for your interest.
1. Philips C. (Name changed for privacy) age 10 5/13/06 sph. cyl. axis bare eye O.D. -2.00 -0.50 90 20/120 O.S. -2.00 -0.50 90 20/120

9/28/06 sph. cyl. axis bare eye O.D. -1.75 0.00 20/60 O.S. -2.00 0.00 20/60
I should also point out that astigmatism sometimes also changes "strangely". It is either that or these optometrists didn't examine the eyes properly. See the following case:
This mother of two boys heard of me through her friends and called me. I asked her to bring all of the old glassess of the two boys when she came.
Here is her older son, Andrew C. (Name changed for privacy) age 11 1st pair of glasses, made in 2002: sph. cyl. axis O.D. -2.75 0.00 O.S. -3.25 -0.25 95
2nd pair of glasses, made in 2003: sph. cyl. axis O.D. -4.50 -0.25 45 O.S. -5.50 -1.00 105
3rd pair of glasses, made in 2004: (This pair was lost) sph. cyl. axis O.D. -5.25 ? ? O.S. -7.50 ? ?
4th pair of glasses, made in 2005: sph. cyl. axis O.D. -6.00 -1.00 95 O.S. -9.00 -0.50 135
5th pair of glasses, made in August, 2006: sph. cyl. axis O.D. -7.25 -0.25 95 O.S. -10.00 -0.50 135
Interesting facts: 1. Astigmatism in his left eye (O.S.) changed from -1.00 (2003) to -0.50 (2005) 2. Astigmatism in his right eye (O.D.) changed from -1.00 (2005) to -0.25 (2006)
The following is my record of Andrew C. (Name changed for privacy) age 11 11/4/06 sph. cyl. axis O.D. -7.75 -0.50 180 O.S. -10.00 -0.50 135
11/18/06 sph. cyl. axis O.D. -7.00 0.00 O.S. -9.50 0.00
12/2/06 sph. cyl. axis O.D. -6.75 0.00 O.S. -8.50 0.00
1/6/07 3:00p.m. sph. cyl. axis O.D. O.S. we'll see.......
The conclusion here is that astigmatism can be reduced and cured, so can nearsightedness.

The difference is that I am not a "follow the dead book" or "follow the false education" type of person. I am a truth seeker. I want to find the truth. I want to understand the real science, not "business-based science".
> WELCOME TO THE SCI.MED.VISION NEWSGROUP > [quoted text clipped - 5 lines] > remedied, as well as items related to new research and > associated findings. When there is a new finding, I will try to learn more about it, understand it, if it somewhat makes sense, some people tried it with good results, I will then try it out myself to prove that it is true.
I won't say things like: the study/research doesn't say so, you are lying, you are a liar. On the contrary, I will try to understand it and experiment with it.
If the problem can't be solved, it means the theories are incorrect.
Suppose that your child comes home from school one day walking with a cane and says, "Mom, I can't walk right any more. They tell me I'll have to use this cane the rest of my life and that it will only get worse. And one third of the other kids in school are also going around with canes or crutches. They said that I inherited this, but you and dad aren't crippled. My grandparents aren't crippled. I don't understand this. What's happening to me?"
Now suppose that your child comes home from school one day and says, "Mom, I can't see the words on the board like I used to. Everything is blurred. They say I am nearsighted and need glasses. They say I'll have to wear the glasses the rest of my life and that it will only get worse. And one third of the other kids are already wearing glasses. They say that I inherited this, but you and dad aren't nearsighted. My grandparents aren't nearsighted. I don't understand this. What's happening to me?"
In reality, can the external doctor help prevent the patient's small leg injury from getting worse and cure it? The answer is YES.
Now, in reality, can the eye doctor help prevent the patient's newly acquired myopia from getting worse and cure it? The answer is YES, ABSOLUTELY.
In reality, can the eye doctor help prevent a ten-year-old child's low myopia from getting worse? The answer is YES, ABSOLUTELY.
In reality, can the eye doctor help prevent a ten-year-old child's medium myopia from getting worse? The answer is YES, ABSOLUTELY.
Again, if the problem can't be solved, it means the theories are incorrect.
In reality, a myopic child's eyeball does not grow longer and longer until he/she reaches adulthood.
I became an optometrist because I wanted to save people's eyes, not for the money. None of my patients need to come back for a new pair of glasses, year after year. I always tell my patients that one day I will die of hunger. However, I will die of hunger happily, since I enjoy what I do, and, hopefully, I will go to heaven.
Sincerely, S.Seagal, O.D.

Dear William Stacy,
> The other "Dr." is just wrong. 1.25 cyls just don't disappear, and the idea of ignoring it > is a bad one, if you're interested in sharp vision. You are right about this as far as "conventional optometry" is concerned. However, when it comes to Real Optometry, True Optometry, or REAL EYECARE, astigmatism (and nearsightedness) can be reduced or completely eliminated if it is not too severe.
"Conventional optometry" deals with sharp vision (quick fix) wearing glasses, which has side effects or bad consequences. REAL EYECARE helps people attain sharp vision bare eye (slightly slower fix).
I am interested in bare eye sharp vision, so are my patients. Of more than a thousand patients I have seen so far, not even one failure.
> The other "Dr." is just wrong. If you say I am wrong, I guess that means my patients came from Mars, since things like these don't happen in "conventional optometry" in this world.
Sincerely, Dr. Seagal

You've gotten 2 bizarre answers, probably more to come. Assuming the Rx is indeed a CLRx (not a spectacle Rx that is "OK for contacts" type), you can get the -11 (no more, and I'm amazed to see who suggested that little tidbit), and then have the resudual measured while you are wearing the contacts for the over-wear glasses. The other "Dr." is just wrong. 1.25 cyls just don't disappear, and the idea of ignoring it is a bad one, if you're interested in sharp vision.

I'm probably using the wrong terms, but hopefully you'll get my point. If I have a contacts prescription of -11 sph, -1.25 cyl. What would happen if I wore spherical contacts -11 and left the astigmatism uncorrected? What would my "equivalent" vision be like?
The reason I'm asking is because they do not make disposable contacts with my prescription, only custom-made torics. But they do have spherical disposables at the same power. I'm just wondering if I could see decently (everything except reading and driving) without correcting astigmatism.
