Multi-layered contact lens element for at least one of examination and treatment of ocular tissues. The multi-layered contact lens element includes a plurality of lens elements in layers including a first lens element having a recess capable of holding a volume of liquid against a cornea of an eye to be examined or treated. Contact lens element for at least one of examination and treatment of ocular tissues includes a lens including a contact surface and an exterior convex surface, the contact surface including a protruding contact ring which forms a recess which is capable of providing a volume for liquid between the lens and a cornea of an eye to be examined or treated when the protruding contact ring is in contact with the cornea. A system for at least one of examination and treatment of ocular tissues includes: an optically clear liquid having a refractive index greater than 1.338; and a contact lens element capable of holding the liquid against a cornea of an eye to be examined or treated. A system for at least one of examination and treatment of ocular tissues includes: a liquid; a contact lens element having a recess capable of holding a volume of the liquid against a cornea of an eye to be examined or treated; and a microscope connected to the contact lens element. A system for examining ocular tissue includes: a microscope having at least one lens including an external lens; and a transparent, malleable material attached to the external lens of the microscope, the malleable material being capable of contacting and conforming to a cornea of an eye to be examined or treated.
