Abstract: A method for operating electronic glasses including a display and a processor is provided. The method includes the steps of taking an image to be displayed as input data, distorting the original image through image manipulation executed by the processor in relation to the vision impairment based on predefined distortion criteria creating pre-compensated image data, first increasing the relative brightness of the pre-compensated image data generating increased brightness image data, second increasing the contrast of the increased brightness image data generating increased contrast image data, and displaying the generated image data on the display.

Abstract: A surgical template (10) comprises at least one a drill guide bore (70) surrounded by a guide bore ring (71) and is adapted to be positioned within the oral cavity of patient. The template (10) comprises an inner rail (20) and an outer rail (30) with an interspace (60) in between. At least three inner and three outer connecting points (81, 82) are provided on the inner and outer rail (20, 30) which are adapted to be positioned on portions of the dental apparatus of the patient in his oral cavity to define the three dimensional position and orientation of the at least one drill guide bore ring (71). The rails (20 and 30) are provided in a predetermined varying distance one from the other allowing accommodation of the inner and outer connecting points (81 and 82) on the rails (20, 30), wherein the template (10) further comprises at least two connecting webs (40) connecting the inner rail (20) and the outer rail (30) in a predetermined distance one from the other.
