You may have realised by now that the floaters are parasites. Fear not we have to fight them on all fronts!
If nobody has helped as in my case, consider making your own eyedrops! Yes I have done it and safely!
Checkout siliconvalleyguryu.com where you will find several remedies for eyes. These are 2 eyedrops you can make:
1)Garlic clove steeped in Rosewater or sterilized water for 15 minutes(pinch the clove) along with 'one piece of 'Fiktari' -this may also be called Faktadi according to the region in India and may come as a white powder. It is good for eliminating stinging sensation in the eyes -normally parasites. Yes your eyes will sting a little initially but I have safely used it for 2 years now.
2nd remedy is Lime juice in rosewater. I have made up my own carefully observing the protocols of sterilization. 1 teaspoonfull of rosewater and one of lime juice. Filter through a clean cloth and make sure its clean! It's for your eyes. When alarming cataract symptoms appeared in my right eye: cloudiness and 'something in the eye' sensation emerged, I decided to make them up.Yes of course the lime stings a bit! Put up with it: your cleansing your eyes and eliminating the parasites. In 2 minutes or less wash your eyes out with water! You will want to do so! My experience was that my right eye no longer had the cloudiness or pain in it: that was 2 weeks ago! !
The garlic mix eliminated my persistent sting in my eyes and on using the lime/rosewater drops have had no recurrence of the cloudiness which implied cataracts. These are old Indian remedies probably used for hundeds of years and passed on.
Why haven't you heard of these remedies? Very simple!
They are basic and easy to make and no profits are involved!
The established [pharmeceutical companies rely on people not being confident enough to make (some)of their own home remedies, so you we all have to rely on them! Thanks but no thanks!
Obviously I am no Doctor, and am only recounting my own experiences.
Good luck with your floaters!
