Thanks to everyone who responded. Haven't been on the site as have had a few bad days as the horrid mist and floaters iin my eye is really getting me down.
Got a few ideas of other things to try. Feeling I might have tried viscotears and they made my eyes itch but I think Optive which I use is the same type of thing. Nurse told me not to use Optrex lotion because of risk of infection from the eye bath, but I might try the drops.
