> Does anyone know why it is so hard to develop such a lens ? As far as medical breakthroughs it seems like low hanging fruit ... Not in medicine or medical research, so great grains of salt required. 1) immune rejection 2) non-degradable 3) same modulus of elasticity as a biological lens (and maintains elasticity) 4) (relatively) cheap source materials 5) (relatively) cheap manufacture 6) survive all testing; up to FDA approval Can anyone in medicine comment on this?
