The author of the talk cites this study in support of his method of defocusing or 'print pushing' : http://iovs.arvojournals.org/article.aspx?articleid=2126435 http://iovs.arvojournals.org/article.aspx?articleid=2126435 Small sample (N=28), but highly significant (p<0.0001) change in optical axial length.
