Don't know about the "deposits" in the retna, but the fast growing cataracts are usually 'fixed' by being surgically removed and having an occular implant put in place of the clouded cornea.

I had fast growing cataracts in both eyes in 2006, caused by a reaction to steroidal eye cream.

When the eye specialist does the cataract removal/implant replacement, they can put in a lens with what ever corrective power you might require.

I had been extremely near-sighted since I was in the 3rd grade, so chose to have my vision corrected for good distance vision, so I can do outside sports activities (driving, riding, skiing) with out need for glasses.

However, like all other 50+'ers, I now need 'cheater' glassed to read, and use the computer. Since I had worn glasses for 45 years, this is no biggie, being greatly outweighed by NOT needing glasses to ride or drive (passed my drivers eye test back in Feb with no glasses). As a matter of fact, my far vision after the cataract surgery was 20-15 in one eye and 20-10 in the other eye.

They do make multi-focal (near/far) corrective lenses, but they are still semi-experimental, and cost more $$ (insurance doesn't pay for them). If and when you get to that point, the eye specialist will cover that with you, and you can find out all kinds of stuff about them online (Google is your friend).

I use a 'press-on' plastic bi-focal lense on the right side of my cycling glasses so I can see the speedometer on the bike, and carry the cheaters for reading menus and fixing flats.

The eye doc I went to...his clinic made a video of the cataract removal and the implant 'installation'. I watched one of them....that was enough for me.

Good luck with your eyes, and keep us posted.
