High eye pressure after cataract surgery

High eye pressure and inflammation after cataract surgery and surgeon doesn't know why with all the eye drops and was put on predisone pills with bad side effects still going on after tapering off. Been 9 months since surgery and surgeon wants to do tear duck surgery and maybe Stent surgery after. Tell me your thoughts please and not at ease at all with knowing more complications can right plus high pressure can get higher after surgery.
