Hello there we understand your oaon amd your moms condition too. And we appreciate your concern towrds your mother. It is expected that moat of them develop redness in their eyes after cataract surgery. That is normal reaction of the body to the surgery after all that disturbance that has been caused to it. But then it is an ophthalmologist duty to desensitise it with an anti cingestion eye drops. I suppose you're using that. If thats nit the case you can go ask your doctor for better drops. Thank you
