Also not sure if all of you are aware that IOL are for the treatment of Cataracts. Which opens up a whole new field of opportunity. IMO of course.
"Intraocular lens (IOL) is a lens implanted in the eye used to treat cataracts or myopia. The most common type of IOL is the pseudophakic IOL. These are implanted during cataract surgery, after the cloudy crystalline lens (otherwise known as a cataract) has been removed."
