Summary:The instrument (10) has a projection apparatus (11) comprising an illumination device and an aperture device, where the illumination device comprises a light source (25) e.g. LED, and the aperture device obtains an image pattern of a surface of an eye (13). A monitoring apparatus (12) comprises a camera (36) and an objective lens (37) and records images of the image pattern, where the topography of the surface of the eye is derivable from the images, and the magnification of the images is varied by the objective lens. An independent claim is also included for an analysis method for measuring a topography of a surface of an eye.
