Gonio lens system with stabilization mechanism
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.
1. A gonio lens system, comprising:
a handle including a stabilization bracket having one or more protrusions for positioning on the eye;
a gonio lens; and
a stabilization mechanism configured to couple the gonio lens to the handle, the stabilization mechanism further configured to allow the gonio lens to move relative to the handle, wherein the stabilization mechanism can rotate or translate relative to the handle and wherein the stabilizing mechanism couples to the bracket of the handle so as to allow the bracket to relative to the handle and stabilize the protrusions relative to the eye.
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 , wherein the stabilization mechanism includes 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 a lens bracket.
4. The system in claim 3 , wherein the lens bracket is pivotally mounted to a support of a stabilization bracket, with the stabilization bracket pivotally mounted to a bracket extending from a distal end of the handle.
5. The system in claim 4 , wherein at least one of the lens bracket, stabilization bracket and stabilizing bracket is U-shaped.
6. The system in claim 3 , wherein the lens bracket includes a tab which mates with a biasing member secured to a part of the stabilization mechanism in order to limit rotational movement of the lens bracket and bias the gonio lens towards the eye.
7. 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.
8. 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.
9. 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.
