Apparatus to treat an eye comprises an annular retention structure to couple to an anterior surface of the eye. The retention structure is coupled to a suction line to couple the retention structure to the eye with suction. A coupling sensor is coupled to the retention structure or the suction line to determine coupling of the retention structure to the eye. A fluid collecting container can be coupled to the retention structure to receive and collect liquid or viscous material from the retention structure. A fluid stop comprising a porous structure can be coupled to an outlet of the fluid collecting container to inhibit passage of the liquid or viscous material when the container has received an amount of the liquid or viscous material. The coupling sensor can be coupled upstream of the porous structure to provide a rapid measurement of the coupling of the retention structure to the eye.

Liquid optical interface for laser eye surgery system

An ophthalmic system may comprise an imaging device having a field of view oriented toward the eye of the patient; a patient interface housing defining a passage therethrough, having a distal end coupled to one or more seals configured to be directly engaged with one or more surfaces of the eye of the patient, and wherein the proximal end is configured to be coupled to the patient workstation such that at least a portion of the field of view of the imaging device passes through the passage; and two or more registration fiducials coupled to the patient interface housing in a predetermined geometric configuration relative to the patient interface housing within the field of view of the imaging device such that they may be imaged by the imaging device in reference to predetermined geometric markers on the eye of the patient which may also be imaged by the imaging device.

Patient interface for ophthalmologic diagnostic and interventional procedures

One embodiment is directed to a method for interfacing an ophthalmic intervention system with an eye of a patient, comprising: placing a patient interface assembly comprising a housing, an optical lens coupled to the housing, and an eye engagement assembly coupled to the housing, the eye engagement assembly comprising an inner seal and an outer seal, into contact with the eye of the patient by sealably engaging the eye with the inner and outer seals in a vacuum zone defined between the inner and outer seals; applying a vacuum load between the inner and outer seals to engage the eye using the vacuum load; and physically limiting an amount of distension of the eye in the vacuum zone.

A method for ophthalmic intervention on an eye of a patient includes: imaging a first and a second registration fiducial in reference to temporary geometric markers on the eye of the patient, the registration fiducials being formed on an inner annulus of a patient interface housing within a field of view of an imaging device; imaging a third registration fiducial formed on the inner annulus of the patient interface housing, the third registration fiducial being angularly spaced from the first and second registration fiducials; and processing image data generated via the image device so as to determine an angular orientation of the eye relative to the patient interface housing and an up or down orientation of the patient interface housing relative to the eye based on the location of the third registration fiducial.

A patient interface assembly for interfacing an ophthalmic intervention system with an eye of a patient includes a housing, an optical lens coupled to the housing, an eye engagement assembly coupled to the housing, the eye engagement assembly including an inner seal and an outer seal, and a tissue migration bolster structure positioned between the inner seal and outer seal and configured to apply a resisting load against portions of the eye in a vacuum zone which are capable of distending upon application of the vacuum load. The eye engagement assembly is adapted to be placed into contact with the eye of the patient by sealably engaging the eye with the inner and outer seals, thereby defining the vacuum zone as being between the inner and outer seals when placed into contact with the eye.
