Abstract
a laser-based ophthalmological treatment system(200) may include a device housing(202), a head fixation assembly(206), and an interactive display device(324, 424). The head fixation assembly(206) may be configured to position and to retain a head of a patient relative to the device housing(202). The interactive display device(324,424) may be positioned in an optical path(304,404). The interactive display device(324,424) may be fixed relative to the head fixation assembly(206). The interactive display device(324,424) may be configured to display a simulation scene(504) that may include a target image(502) into a visual field of the patient. The target image(502) may be displayed in the simulation scene(504) such that optical focus on the target image(502) by the patient aligns a portion of a fundus(130) of an eye of the patient in the optical path(304,404).
