It's very easy to get confused. The situation with these eye health supplements is analogous to toothpaste. If I go into the store to buy toothpaste, well, I'm going to find at least a dozen different types of Crest toothpaste. There's Crest with Scope, Crest with tartar control, Crest with baking soda, Crest whitening, and on and on.
Here is the Bausch and Lomb page for Ocuvite. Notice how many Ocuvite products there are:

George is correct that the current recommendation for both the "dry" and "wet" forms of macular degeneration is the Preservision AREDS Formula 2. (Preservision is also from Bausch and Lomb, by the way.) Costco often has the best price, and often runs sales. Those with the "wet" form also receive injections of medication into the eye.
The original article that Richard posted is interesting because approaching treatment of macular degeneration via the complement pathway is a new idea. The injectable drugs that we have now target something called VEGF (Vascular Endothelial Growth Factor).
But as always, there is a problem with what's called the blood-retina barrier. The brain and the eye "protect" themselves so that many molecules circulating in your bloodstream can't get in. (That's why the anti-VEGF drugs are given by injection directly into the eye, to bypass the blood-retina barrier. The drugs would be useless if given by mouth or intravenously.) So even if there were some possible treatment that might aid macular degeneration patients by working on the complement pathway, an important question is how would it be administered. It would be wonderful to have a drug that could be administered as a pill, but it would have to penetrate the blood-retina barrier.
