Sorry to hear that. I forget exactly the diagnosis but maybe it was meibomian gland dysfunction and/or blepharitis? How deep? Basically with one hand pull your eyelid up or down (depending on which one) and then while keeping your eye open, which I find quite hard, wipe along the pink line of the eyelid with the eyelid wipe backwards and forwards ten times. It has to be along this line as that's where the glands are. Do this for both top and bottom eyelid. If it's really bad like mine was you might need to take some medication - I was put on steroids I think. Sorry memory not serving me hugely well here but good luck! I'll check for comments in case this wasn't clear enough.
