This case involves a 68-year-old patient who suffered permanent vision loss following an eye cataract surgery with lens implant. Before the surgery in question, the intraocular pressure in her eye was found to be elevated. She was started on medicated drops, but the pressure remained high at the time of surgery. She was told not to worry and that the pressure would return to normal after the procedure. No imaging or measurements were done at that time. A week after the surgery, the patient returned with a painful, red eye and complained of blurry vision. There were a series of delays in getting the patient to surgery, and she went several months without medical treatment. During the months without medical treatment, the patient suffered complete and permanent vision loss in her eye.
