Abstract
Described herein is a device for performing scleral depression. The device can include a ring and one or more arms protruding from the ring. The ring can define an opening over an eye and include a handle protruding away from the one or more arms. The opening can have a diameter that is at least 6 to 8 millimeters (mm) long. The one or more arms can be configured to be disposed over a globe of the eye for controllable depression of a sclera of the eye. Uniform pressure can be applied to the sclera by depression features at a distal end of each of the one or more arms.
Claims20
A device for scleral depression, the device comprising:
- a ring defining an opening with a diameter of 6 to 8 millimeters (mm);
- and
- at least three arms protruding from the ring in a first direction, the at least three arms being equidistantly positioned around a circumference of the ring;
- wherein each of the at least three arms have a curvature configured to conform to a globe of an eye and each of the at least three arms extends radially inward from the ring such that a distal end of each arm lies inside an inner circumference of the ring, and wherein the at least three arms are configured to be disposed over the globe of the eye for controllable depression of a sclera of the eye.
A device for scleral depression, the device comprising:
- a ring defining an opening with a diameter that is about 6 to 8 millimeters (mm);
- and
- at least three arms protruding from the ring in a first direction, the at least three arms being equidistantly positioned around a circumference of the ring,
- wherein each of the at least three arms have a curvature configured to conform to a globe of an eye and each of the at least three arms extends radially inward from the ring such that a distal end of each arm lies inside an inner circumference of the ring, and wherein each of the at least three arms further comprise:
- a depression feature at a distal end of each of the at least three arms,
- wherein the depression feature of each of the at least three arms are configured to apply pressure to a sclera of the eye to induce depression of the sclera, and
- wherein the at least three arms are configured to be disposed over the globe of the eye and to controllably induce the depression of the sclera for ophthalmic procedures.
A device for scleral depression, the device comprising:
- a ring defining an opening with a diameter that is at least 6 to 8 millimeters (mm), wherein the ring comprises:
- a handle for rotating the device about a vertical axis of an eye;
- and
- at least three arms protruding from the ring in a first direction, the at least three arms being equidistantly positioned around a circumference of the ring,
- wherein the at least three arms have a curvature configured to conform to a globe of an eye and each of the at least three arms extends radially inward from the ring such that a distal end of each arm lies inside an inner circumference of the ring, and wherein the at least three arms are configured to be disposed over the globe of the eye for controllable depression of a sclera of the eye.
