Abstract
An eye stabilizing mechanism for use with a computer controlled ophthalmic laser system includes a base on which the ophthalmic laser system is mounted. A frame is slidingly mounted on the base, and the frame is connected to the base by a linear spring. A contact lens is fixedly attached to the frame and an object lens is slidingly mounted on the frame. An object lens activating device is also fixedly attached to the frame, and this device is connected to the object lens to move the object lens in accordance with preprogrammed instructions from the computer. Thus, while contact is maintained between the surface of the eye and the contact lens, the object lens can be moved by computer control to move the focal point of the laser system through selected eye tissue. Also, any movement of the frame, due to movement of the eye, is opposed only by the substantially constant force which is established by the linear spring between the base and the frame.
