Shortened slit lamp microscope

摘要

An eye examination device including eye examination optics for examining a patient's eyes. A chin rest assembly accepts the patient's head and maintains the patient's head in a fixed stable position. The chin rest assembly can comprise two spaced apart upright posts for securing to a table, with a forehead rest member being secured to the two upright posts at an upper end, and a chin rest member being secured to the two upright posts below the forehead rest member. The chin rest member can have a chin rest portion which extends forwardly relative to an upright plane extending between centers of the two upright posts and away from the eye examination optics, so that generally only a front of the patient's face coincides with the upright plane when the patient's head engages the chin rest portion.
