I think lanosterol eye drops will reverse cataracts in humans if the lanosterol is supplied to the eye as nanoparticles. Such a nanoparticle eyedrop has already been made available to dogs at http://www.lanomax.com
The problem with that eyedrop was that they used a phosphate buffer to maintain constant pH. Phosphate may cause corneal or lens calcification, therefore I did not use those eye drops.
We are hoping that Acucela Inc. will run clinical trials of lanosterol eyedrops in the US in November 2017, or early 2018. My cataracts are already mature/yellow, but we don't want surgery from people (eye doctors) who openly admit they don't want to cure cataract.
