Abstract
The present invention concerns 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, the object can be contacted. In the case of an eye, a contact element structure contacts the eye and moves with the small rotational movement of the eye. The contact element is mounted to rotate about a pivot point which is outside the eye. The device forms a image of a portion of the eye which does not move laterally with small eye movements. A examining instrument, e.g., a biomicroscope, may be focused on the image. In laser treatment of the retina or other regions of the eye the laser beam can be directed through the system so that the position of the laser beam will be stabilized at the derived point.
