UK Keratoconus Self-Help and Support Association

I have dry eyes and have found this the best but its expensive. These are the best prices I can find at the moment on line

https://www.ebay.co.uk/itm/2-x-HYLO-FOR ... SwaZdZ133U
£8-95 each

https://www.ebay.co.uk/itm/HYLO-FORTE-E ... SwnCFZ~qK2
£9-00 each

https://www.ebay.co.uk/itm/BNIB-2-x-HYL ... SwiIxZ6LDG
£10-00 each

Are there other ways and means of sourcing it cheaper, for instance a GP prescription?

I get it on pescription but from my specialist as the GP doesn't have funding to rx it yet hospital does, without a combo of hylo forte n hylo tears my eyes are unmanagable.

Hi
My Gp gives Hylo Forte PF on prescription once the hospital put me on it.
Kind regards
Sheila
