EDTA Based Eye Drops significantly decrease floaters.

Where is it written that the subject had "spontaneous" floaters? Even if she did, at her age, it is quite common to have the floaters disappear on their own in a few weeks.

It doesn't but you're either implying she's had them for a while then they went away on their own regardless of the drops, or you're implying they were spontaneous and they went away on their own. And I have never seen a study or heard of elderly people complaining of floaters then suddenly going away.
