since you have had multiple surgeries in the right eye, the most common cause or irritation is dryness of eye
this can be remedied by instilling lubricating eye drops like refresh tears/genteal/systane etc (available over the counter)
if the itching is of recent origin, then you might be having some allergy also
in that case, you can also use ati-allergy eye drops like zaditen/naphcon-A etc (again available over the counter)
but if despite this treatment, there is no relief, then you can consult your Ophthalmologist for a first hand evaluation
I will seek out best course of treatment by speaking to someone in my local pharmacy and/or my optician. I was just concerned because of multiple surgeries whether I should go to A&E at Moorfields but it seems a bit drastic and if I can avoid sitting for 3+ hours waiting to be seen, then that would be preferable.
for a mild irritation or itching you need to not go immediately to A&E at Moorfields
you can try the lubricating and the anti-allergy eye drops and then decide depending on how you feel after a few days
Thanks. Will do.
