发明名称 Ophthalmic image stabilization system
摘要 Disclosed are a system and a method for stabilizing the image of an object when the motions of that object are small, the motions are either rotatory or straight-line, and the object can be contacted. In the case of the eye a contact element structure contacts the eye and moves with the small rotational movements of the eye. The contact element is mounted to rotate about a pivot point which is outside the eye. The device forms a virtual image of a portion of the eye; this image is stabilized in that the virtual image does not move laterally with the small eye movements. The examining instrument, e.g., a biomicroscope, is focused on the virtual image. In laser treatment of the retina or other regions of the eye the laser beam can be directed through the system to the stabilized image.
