OPHTHALMIC INTERFACE APPARATUS, METHOD OF INTERFACING A SURGICAL LASER WITH AN EYE, AND SUPPORT RING FOR USE WITH A SUCTION RING
First Claim
1. A support ring for use with a suction ring of an ocular stability device, the support ring comprising:
- a first end surface;
a second end surface opposite the first end surface having a width that is greater than a width of the first end surface, the second end surface extending toward a central opening in the support ring to define a concave curvature configured to substantially match a curvature of a patient'"'"'s eye; and
an outer surface extending between the first end surface and the second end surface, the outer surface including an annular groove formed adjacent the first end surface and a plurality of exterior vacuum channels spaced around the annular groove and extending axially from the annular groove to the second end surface.

Abstract
Apparatus and methods are provided for interfacing a surgical laser with an eye using a patient interface device that minimizes aberrations through a combination of a contact lens surface positioning and a liquid medium between an anterior surface of the eye and the contact lens surface. Further, support rings, ocular stability devices, and methods for interfacing an eye during laser surgery are provided. In an embodiment, by way of example only, a support ring includes a first end surface, a second end surface opposite the first end surface, and an outer surface extending between the first end surface and the second end surface. The second end surface has a width that is greater than a width of the first end surface and extends toward a central opening in the support ring to define a concave curvature configured to substantially match a curvature of a patient'"'"'s eye. The outer surface includes an annular groove formed adjacent the first end surface and a plurality of exterior vacuum channels spaced around the annular groove and extends axially from the annular groove to the second end surface.

21. A method of interfacing with an eye during a laser surgery comprising:
-
contacting a support ring to an anterior surface of the eye, the support ring being disposed in a cavity of a suction ring, the cavity defined between an outer annular wall, an inner annular wall, and a radially extending wall of the suction ring, the support ring including; a first end surface, a second end surface opposite the first end surface, the second end surface having a width that is greater than a width of the first end surface for contacting the eye and extending toward a central opening of the support ring to define a concave curvature configured to substantially match a curvature of the eye, and an outer surface extending between the first end surface and the second end surface, the outer surface including an annular groove and a plurality of exterior vacuum channels, the annular groove being formed adjacent the first end surface, and the plurality of exterior vacuum channels being spaced around the annular groove and extending axially from the annular groove to the second end surface; and applying a vacuum suction to the anterior surface of the eye via an orifice extending from the suction ring, the orifice being in communication with the annular groove and the plurality of exterior vacuum channels. - View Dependent Claims (22, 23)
