Abstract
An optic system for viewing the inside of the eye with a lens system. The lens system has a concave lens surface configured to be placed onto the cornea of an eye. The lens system has furthermore at least one further lens arranged in viewing direction in front of the first lens. The area to be viewed is also illuminated, whereby this illumination will not result in reflexes on optical surfaces. Furthermore, such an optic system is small, lightweight and compact that it neither interferes during a pre-surgical or post-surgical diagnosis nor during surgery. The optic system has for this purpose an illuminating device, the light-exiting surface of which lies within the first lens, or terminates flush with a lens surface of the first lens.
