It’s dumb like wood. Many cyclopegias, zero difference. 0.5 D at most.
Even with 1% atropine, nothing at all has changed. 0.00, literally.
But if you suggest I can’t have spasm due to no difference from cycloplegia + I never wore full correction (this might be not true as accommodative loop due to near esophoria might be times stronger and equal by time with regular screen-staring using full correction, then I can’t get a thing I have so few amounts of accommodation.
I remember Yee saying lens is bulged at high myopia independent of the ciliary muscle.
The evidence of this is ciliary being thicker in myopes, as well as myopes difficulty to accommodate.
So Ortho C brought an improvement of 2-2.5 D at one high myope he treated.
But due to bad habits of former (I suspect) her vision almost returned to starting point after years.
John Yee stopped to answer me by email when he said he will not guide me in treatment since I have esophoria and too much astigmatism. And he usually does not treat high myopia.
So I can either make a fake email or dig into his book how to use Ortho C. If I will get normal treatment of strabismus (vision therapy or/and surgery).
