Abstract
The invention provides a universal gonioscope-contact lens system suitable for diagnostics and intraocular laser surgery. The device consists of a hollow gonioscope body with a plurality of mirrors on the inner walls of the body and a contact lens. The front part of the lens is intended for contact with the eye cornea, while the rear part of the lens has a tapered shape with flat portions arranged perpendicular to the beams reflected from the gonioscope mirrors. The tapered portion of the lens can be conveniently used for manipulating the lens and for arranging optical lens components such as a concave lens and convex lens.
Claims23
A universal gonioscope-contact lens system suitable for observation and intraocular laser surgery comprising:
- a hollow gonioscope body having an optical axis and an inner surface with at least one light-reflecting means on said inner surface for reflecting a beam, which is incident on said at least one light-reflecting means in the direction parallel to said optical axis;
- and
- a contact lens portion for placing onto a patient's eye, said contact lens serving as a support for said hollow gonioscope body and comprising a front contact lens portion intended for contact with the patient's eye and a rear main optical portion of any arbitrary shape that has at least one flat surface;
- said at least one light-reflecting means on said inner surface being inclined at an acute angle to said optical axis so that when said incident beam parallel to said optical axis is reflected from said light-reflecting means, said incident beam will fall onto said at least one flat surface in a substantially perpendicular direction.
