Abstract
A device for controlling the position of a patient's eyes during ophthalmic laser surgery is disclosed which comprises a first fixation object positioned within view of the patient's eye that is undergoing treatment, a second fixation object positioned within view of the patient's eye that is not undergoing treatment, and structure for controlling the position of the second fixation object. The present device allows the patient to maintain fixation on a visual target and maintain the eye undergoing treatment in a steady position even when vision in the eye undergoing treatment becomes blurred during laser ablation.
