摘要：
A non-sliding, non-sutured hands-free contact lens assembly for ophthalmic procedures utilizes a number of microstructures strategically placed on the bottom of either the contact lens or the bottom of a contact lens holder ring. After the contact lens, or the contact lens assembled with the contact lens holder ring, is placed on the cornea of the eye and centered, a surgeon applies downward pressure either on the contact lens itself or on the lens holder ring. This secures the lens assembly to the cornea due to increased friction between the microstructures and the tissues of the eye when the microstructures penetrate through the tear film and, optionally, viscous solution film and into the contact with superficial layer of cornea or other parts of the eye, thus temporarily anchoring the contact lens, or lens holder, to the desired surgical site.
