An apparatus for obtaining an image of a cornea comprising:

• a stereomicroscope configured to obtain and display 2D or 3D image content of an eye of a patient;
• pupil imaging optics configured to form a pupil along an optical axis, to form an image of an iris, and to convey the light along the optical axis to form the cornea image on an image sensor, wherein the pupil imaging optics are further configured to form the cornea image when mounted on the stereomicroscope and when hand-held;
• a shutter disposed at the formed pupil and configured to form a pattern of one or two apertures for light along the optical axis, according to signals from a control logic processor;
• and
• an input prism disposed between the shutter and the image sensor and configured to direct light to or from the optical axis.
