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.

Hybrid ophthalmic interface apparatus and method of interfacing a surgical laser with an eye

System and method of photoaltering a region of an eye using a high resolution digital image of the eye. The system includes a laser assembly for outputting a pulsed laser beam, an imaging system for capturing a real-time high resolution digital image of the eye and displaying the digital image of the eye, a user interface receiving at least one laser parameter input, and a controller coupled to the laser assembly, imaging system, and user interface. The controller directs the laser assembly to output the pulsed laser beam to the region of the eye based on the laser parameter input.

Ophthalmic laser apparatus, system, and method with high resolution imaging

Systems, apparatus, and methods are disclosed for locating tissue layer transitions within a cornea, including focusing a laser to a laser spot with an energy below a photodisruption threshold of the cornea, varying a position of the focal spot of the laser between an anterior surface of the cornea and a posterior surface of the cornea, and determining one or more transitions of the tissue layers based on a change in harmonic light generated by the laser spot.

Apparatus, system and method for precision depth measurement

A system for interfacing a surgical laser with an eye includes a first sensing element to couple to an output surface of the laser, an interface lens having second sensing element coupled to a first surface of the interface lens, and a detector coupled to the first sensing element. A second surface of the interface lens contacts the eye. The detector determines when the first sensing element contacts the second sensing element. A method for aligning the laser with the eye includes coupling the laser to the patient interface, sensing an electrical change indicating a position of the output surface with the interface lens, comparing the electrical change with a predetermined value to produce a correction, and re-positioning the laser with the correction.

System and method of interfacing a surgical laser with an eye

Systems and methods of incising a portion of a material include creating a sub-surface separation in a region of the material, and incising a periphery of the region with a pulsed laser beam to produce an edge of the portion. The edge includes a periodically varying shape to secure the portion to the material when the portion is reintegrated. The system includes a laser producing the pulsed laser beam, a scanner operable in response to a control signal, and a controller coupled to the scanner. The controller produces the control signal. In response to the control signal, the scanner creates a sub-surface separation in the region with the pulsed laser beam and incises the periphery of the region with the pulsed laser beam to produce the edge with the periodically varying shape.

System and method for incising material

A system and method for preparation of donor corneal tissue is disclosed. The system includes two surgical lasers. The first surgical laser is adapted to incise a recipient cornea to enable resection of recipient corneal tissue. The second surgical laser is adapted to incise a donor cornea to enable resection of donor corneal tissue. Both surgical lasers are adapted to make corneal incisions which are defined by incision parameters. Further, both surgical lasers are calibrated to make substantially precise corneal incisions when provided with identical incision parameters.

System and method for preparation of donor corneal tissue

An interface for coupling an eye to a surgical laser is disclosed. A lens cone includes a base ring opposite an apex ring. The base ring defines a first plane and is adapted to couple to the delivery tip of the laser such that the first plane has a predetermined position relative to the delivery tip. An applanation lens is affixed to the apex ring and has a surface disposed in a second plane such that the second plane is parallel to and has a predetermined position relative to the first plane. A gripper is engagable with the lens cone. An attachment ring is affixed to the gripper and is adapted to couple to the anterior surface of the eye. When the lens cone and gripper are engaged, the applanation lens contacts the anterior surface of the eye, placing the anterior surface in spatial registration with the delivery tip.

Ocular fixation and stabilization device for ophthalmic surgical applications

A method for applanating an anterior surface of a cornea and coupling the eye to a surgical laser is disclosed. A interface is provided which has a central orifice and top and bottom surfaces. A suction ring is removably coupled to the bottom surface of the interface. The interface is positioned over an operative area of an eye, such that the suction ring comes into proximate contact with the surface of the eye. A suction is applied to the suction ring to stabilize the position of the interface relative to the operative area of the eye. An applanation lens is positioned in proximate contact with the operative area of the eye. Finally, the applanation lens is coupled to the interface to stabilize the position of the lens relative to the operative area of the eye.

A disposable stabilization and applanation device for reconfiguring the cornea of an eye for ophthalmic laser surgery, includes an applanation lens that is disposed in a particular spatial position with respect to an incident laser beam. The applanation lens is inserted into the central opening of an attachment ring and applanates the eye in response to pressure from a lens cone. The attachment ring is coupled to the eye and includes a skirt which surrounds the applanation lens and extends outwardly therefrom to define a chamber. The skirt is formed with a groove which defines a suction channel between the attachment ring skirt and the corneal surface of an eye. A vacuum source is connected and fluid communication with the suction channel and is selectively activated to create a partial vacuum in the channel.
