Contact lens element for examination or treatment of ocular tissues

A contact lens element for at least one of examination and treatment of ocular tissues, comprising a concave surface capable of contacting a cornea of an eye to be examined or treated having a radius of curvature that is less than approximately a radius of curvature of the cornea and having a diameter of about 7 to 12 mm, and an exterior convex surface having a diameter of about 13 to 19 mm, the contact lens element having a thickness of about 8 to 20 mm, wherein the contact lens element includes a hole therethrough for injecting a liquid into a space between the contact lens element and the cornea when the contact lens element is in contact with the cornea, and wherein the contact lens element includes a vent.

A contact lens element for at least one of examination and treatment of ocular tissues, comprising a lens including a contact surface and an exterior convex surface, the contact surface comprising a protruding contact ring which forms a recess which is capable of forming a substantially enclosed space with a cornea of an eye to be examined or treated when the protruding contact ring is in contact with the cornea, the substantially enclosed space being capable of being filled with a liquid and wherein the protruding contact ring protrudes from a concave surface which forms a portion of the recess.

A system for at least one of examination and treatment of ocular tissues, comprising:

• an optically clear liquid having a refractive index greater than 1.338;
• and
• a contact lens element capable of forming a substantially enclosed space with a cornea of an eye to be examined or treated, the substantially enclosed space being capable of being filled with a liquid, and wherein the contact lens element comprises a rounded surface which is capable of contacting a cornea without distorting a shape of the cornea inside of a contact ring region.

A system for examining ocular tissue, comprising:

• a microscope having at least one lens comprising 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, without significantly distorting a shape of the cornea.

A multi-layered contact lens element for at least one of examination and treatment of ocular tissues, comprising a plurality of lens elements in layers including a first lens element having a recess capable of forming a substantially enclosed space with a cornea of an eye to be examined or treated, the substantially enclosed space being capable of being filled with a liquid, and wherein at least one surface of each lens element of the plurality of lens elements contacts a surface of another lens of the plurality of lens elements.

A contact lens element for at least one of examination and treatment of ocular tissues, comprising a concave surface capable of contacting a cornea of an eye to be examined or treated having a radius of curvature that is less than approximately a radius of curvature of the cornea and having a diameter of about 7 to 12 mm, and an exterior convex surface having a diameter of about 13 to 19 mm, the contact lens element having a thickness of about 8 to 20 mm, wherein the contact lens element includes a vent.

A system for at least one of examination and treatment of ocular tissues, comprising:

• an optically clear liquid having a refractive index greater than 1.338;
• and
• a contact lens element capable of forming a substantially enclosed space with a cornea of an eye to be examined or treated, the substantially enclosed space being capable of being filled with the liquid, and wherein the contact lens element comprises at least one hole for filling the liquid.
