First time on MN so please excuse any blunders. My 3 yr old DS is having an operation in a months time to put stints in his tear ducts to widen the passage for 3 months as he has had watery eyes all his life and this leads to gunk. He had a general at the end of november for unblocking tear ducts but this has not worked. Any one had any experience or advice would be greatly appreciated as worried about it.
