Anxiety is common among patients undergoing eye surgery, which is typically performed under topical anesthesia while the patient is awake. This can be an unsettling experience for patients, who may worry about being able to keep their eyes still during surgery, cooperate with the surgical team, and remain immobile in an unfamiliar environment. Patients may also experience anxiety due to concerns about surgical pain, possible complications, and the uncertainty of the outcome of the surgery. In this study, the investigators aimed to investigate the correlation between the severity of anxiety symptoms during LASIK, and fixation instability during photo-ablation as plotted by the eye tracker.
