Abstract

This disclosure relates generally to methods and devices for use in viewing and positioning an eye with a gonio lens system, such as during ocular exams and ocular surgeries. Some embodiments of the gonio lens system can include a gonio lens for viewing one or more tissues and structures of the eye. In addition, the gonio lens system can include one or more positioning features for controlling movement positioning of the eye.

First claim

What is claimed is:

1. A gonio lens system, comprising:
a handle having a forked end that defines two prongs;
a stabilization bracket having one or more protrusions for positioning on the eye, wherein the stabilization bracket is formed of a U-shaped body that is rotatably attached to the forked end of the handle inside the two prongs;
a U-shaped lens bracket attached to the stabilization bracket;
a gonio lens movably attached to the lens bracket.

2. The system in claim 1 , wherein the protrusions include at least one of a rounded shape and a surface feature for controlling movement of the eye.

3. The system in claim 1 , further comprising a lens belt secured to at least a part of the gonio lens, with the lens belt including a pair of extruding pins coupled to a pair of slots extending along a part of the lens bracket.

4. The system in claim 3 , wherein the lens bracket is pivotally mounted to the stabilization bracket.

5. The system in claim 1 , wherein at least one of the handle or stabilization mechanism is made out of one or more materials, including stainless steel, titanium, nitinol, plastics, or other equivalent materials.

6. The system in claim 1 , wherein the gonio lens is manufactured out of one or more materials including optical glass, polymers, or other equivalent materials.

7. The system in claim 1 , wherein the gonio lens is coated with one or more coatings, including coatings which at least one of minimize reflection, increase lens strength, and minimize damage to the lens.
