Abstract
A novel surgical lens system including a lens and a reflective element. The lens is placed on, or above, a cornea of an eye of a subject for enabling inspection of the eye. The reflective element is incorporated into the lens. The reflective element reflects a light beam toward the eye of the subject. The reflective element increases the divergence of the light beam, such that the divergence of the reflected light beam is larger than the divergence of the light beam. The light beam is emitted by a non-invasive light source positioned externally to the eye.
Claims14
A lens system for inspection of an eye of a subject comprising:
- a lens arranged to be placed either one of on and above a cornea of said eye;
- said lens configured to form an image of said eye;
- and
- a reflective element placed away from the periphery of said lens, so that said reflective element partially occludes a field of view (FOV) of said lens, said reflective element is incorporated into said lens;
- wherein said reflective element being configured to reflect a light beam, emitted by a non-invasive light source positioned externally to said eye, and thereby to direct a reflected light beam toward said eye of said subject, said reflective element being further configured to increase the divergence of said light beam, such that the divergence of said reflected light beam is larger than the divergence of said light beam.
