Gonioscope for improved viewing

A gonioscopic assembly comprising:

• a first gonioscopic optical element having a distal surface and a proximal surface, the distal surface being concave and having a radius of curvature between about 5 mm and about 11 mm;
• and
• a handle supporting the first gonioscopic optical element;
• an attachment member coupled to the first gonioscopic optical element;
• a housing movably attachable to the attachment member such that the housing is movable with respect to the attachment member;
• and
• a second gonioscopic optical element supported by the housing, wherein the movably attachable housing is configured to alter the orientation of the second gonioscopic optical element with respect to the first gonioscopic optical element.

A gonioscopic assembly comprising:

• a first gonioscopic optical element having a distal surface and a proximal surface, the distal surface being concave and having a radius of curvature between about 5 mm and about 11 mm;
• a second gonioscopic optical element having a distal surface and a proximal surface;
• and
• a housing that positions the second gonioscopic optical element such that the distal surface is positioned to receive light emitted by the proximal surface of the first gonioscopic optical element;
• wherein the distal surface of the second gonioscopic optical element is spaced apart from the proximal surface of the first gonioscopic optical element to form a gap therebetween, and wherein the gap is at least partially unobstructed so as to allow air flow between the first and second gonioscopic optical elements to reduce condensation formation thereon.

A gonioscopic assembly comprising:

• a first gonioscopic optical element having a distal surface and a proximal surface, the distal surface being concave and having a radius of curvature configured to fit onto an eye of a patient and receive light from a structure within the eye, the proximal surface configured to output the light transmitted through the first gonioscopic optical element;
• and
• a wedge-shaped second gonioscopic optical element having a distal end and a proximal end, the distal end of the second gonioscopic optical element configured to receive light output by the proximal surface of the first gonioscopic optical element, the proximal end of the second gonioscopic optical element configured to output the light transmitted through the second gonioscopic optical element;
• wherein the second gonioscopic optical element is coupled to a microscope such that the light output by the proximal surface of the second gonioscopic optical element is received by the microscope to form an image of the structure within the eye viewable by the microscope.
