Contact glass for ophthalmic surgery

A contact glass adapter for ophthalmic surgery, comprising

• a lens body having a front lens surface for placement onto a cornea of an eye, the cornea of the eye having a corneal diameter,
• a lens mount being integral with the lens body or connected to the lens body, the contact glass adapter having a anterior end and a posterior end, the posterior end being farthest from the eye when the contact glass is applied to the eye and the anterior end being nearest to the eye when the contact glass is applied to the eye,
• wherein a multiplicity of suction orifices is defined in the lens mount, for providing a vacuum on the cornea of the eye through the multiplicity of suction orifices,
• wherein the multiplicity of suction orifices surround the front surface of the lens body and are bordered by the anterior contour of the lens mount,
• wherein the lens mount extends circumferentially around the lens body and is structured such that a complete circumference of the lens mount does not contact the cornea when the front lens surface is in full contact with the cornea.
