Hi, my old Dane had this operation done some 10 years ago, it was a straight forward procedure, although obviously all general anesthetic carries some risk. Floyds' eye was so bad that the cyst looked like a whole other eye was falling out....was nasty!!!! Some days his eye was fine....others, especially after exercise it was really bad. I had it done in the end because I was scared to let him run about and play incase it prolapsed. After his eyes looked slightly different as he had no third lid on one, but he was fine and in never re-occured.
