The linked illumination/ observation system can be moved about independently of the head position, and a fixation target is provided to assist eye positioning and help the patient keep his/her eyes still.

The objective lens is brought forward until the gel comes into contact with the anaesthetized cornea (the objective lens never touches the cornea). The gel serves to optically couple the objective lens of the microscope to the cornea. As soon as the gel contacts the cornea, the computer monitor displays real-time images. The examination room is arranged in such a way that the operator can see the objective lens on the cornea and the video monitor in the same field of view. An automatic scan is then made through the anterior-posterior axis of the cornea.
