Myopia rehabilitation is an experimental field at best. So far, none of the people who claimed recovery or improvement have posted detailed measurements of axial length (AL), corneal curvature and/or lens refraction, verified by optical equipment before and after their efforts. Thus, you should take such claims with a grain of salt.
As you and I have discussed elsewhere, I could of course get myself refracted, but I'm not sure what good this would do, for several reasons:
A. I did not get myself refracted before using incremental defocus methods to work myself out of myopia, so I have no "baseline" for comparison. So if I report an axial length now, you will find it to be persuasive only if you have an earlier measurement with which to compare it. But I can't go back in time to get that number. So a single measurement now is meaningless.
B. Axial shortening of the eye in response to the applied defocus of plus lens has already been demonstrated in numerous animal and human studies (cited in my above response to ScientificMind). These were controlled studies using statistics on sample populations. Far more convincing that my single anecdotal example, I would think.
Now I'll grant there are some questions that have not been studied, which would providing additional support for the practicality of the plus lens method:
Q1. How do the benefits of selective use of plus lenses ONLY at the edge of focus compare with passively wearing plus lenses for distance or all the time?
Q2. How is the effectiveness of the plus lens method affected by age, health, diet, and genetics? Can everyone benefit, or only the young, healthy and genetically favored?
Those last two questions are worth answering. But to answer them conclusively will require more than anecdotal reports. They will require new studies. That won't happen without first convincing researchers organize and funding the studies. We're not there yet.
So for now, all we have to go on are the general mechanistic studies already reported, general physiological knowledge, and the accumulated experience of people like myself and the dozens who have reported progress on this site.
Perhaps some of you who read this and have not yet started the method would like to have your eyes refracted before and after your print pushing work, and you could report the data back here.
