The floaters are likely from the capillary leakage from the macular degeneration.  Silica and natural vitamin C sources since they also contain the flavonoids will help stabilize the macula.  I use a lot of berries in my En-Vision formula for this reason.  I like juniper berry especially for not only the flavonoids but also because it strengthens the optic nerve.  Speaking of juniper berry, people should not collect the berries themselves unless they know what they are picking.  Some species are highly poisonous.

Cataracts are hard to get rid of once they form.  They are easier to prevent.  Natural vitamin Es (mixed tocopherols and tocotrienols) can help prevent most cataracts.  The Chinese use abalone shell powder internally to help dissolve cataracts.  There is also an old time pharmaceutical remedy made from the plant dusty miller that was made in to eye drops to dissolve cataracts.  The solution is somewhat caustic though so you would have to be careful using it.  And I do not know what concentration they used so that is something that would have to be researched.  Supposedly Royal Rife had a lot of success with dissolving cataracts with his machine as well.  I do not know of anyone that has actually used this for cataracts though, so I have no feedback on this method.
