A 50-year-old female is scheduled for laparoscopic cholecystectomy. Her history is non-contributory. She takes no medication and has no allergies. The patient is otherwise healthy and has no complaints. She has removed her glasses and states that she uses no contact lenses. You are joined by a medical student who puts all the monitors on the patient, including the oxygen saturation monitor on her right index finger.

The recovery room nurse calls you to tell you that the patient is complaining of a painful eye. What will you do, and what could cause pain in the eye?…
