    Abstract: A method of re-profiling a cornea of an eye is provided which includes causing ablation energy to be applied across the cornea of the eye and controlling distribution of the ablation energy across the cornea of the eye. The distribution of the ablation energy is controlled by causing the ablation energy to provide an ablation zone, having an optical zone disposed in a central portion of the anterior surface and a transition zone disposed peripherally to the optical zone on an anterior surface of the cornea the ablation zone, and determining a shape of the transition zone by selecting between a cubic spline function and a complementary error function.

    Abstract: Apparatus and methods are provided for interfacing an ophthalmic surgical laser with an eye using a patient interface (PI). The PI may include a closed, fluid-filled bladder having fiducials that contacts and deforms to the eye. Or, the PI may have an applanation lens with an outer ring portion and an inner concave portion for receiving the apex of the cornea. Another PI features a suction ring with a flexible skirt for contacting the sclera that is non-circular and/or non-planar. A system for injecting an index matching fluid into the area above the eye may also be incorporated. An integrated system includes a co-molded lens cone and attachment ring, with a lens window at the bottom of the lens cone which provides a sealed volume for vacuum-attaching a laser delivery system above the lens cone.

    Abstract: A patient interface device includes: a first interface port configured to be interfaced with a laser surgery apparatus; a second interface port configured to be interfaced with a patient's eye, the second interface port including an applanating lens for application to a patient's eye during a laser surgery procedure; a chamber extending between the first interface port and the second interface port and defining a chamber therein, wherein air may be evacuated from the chamber by the laser surgery apparatus via the first interface port; and a tubular light guiding structure having at a first end thereof a light receiving surface, configured to receive light, and having at a second end thereof a light-emitting surface, wherein the second surface is disposed adjacent the applanating lens and configured to provide the light in a vicinity of the patient's eye when the applanating lens is applied to the patient's eye.

    Abstract: Embodiments of the invention provide methods and systems for analyzing the ophthalmic anatomy of a patient posterior to the cornea. The method may include scanning a focus of a femtosecond laser beam along a path within the patient's eye. A portion of the path may be disposed posterior to the patient's cornea. The method may also include acquiring a first reflectance image and a second reflectance image associated with the focus disposed respectively at a first location of the path and a second location of the path. The method may further include determining the presence or absence of an ophthalmic anatomical feature of the eye based on a comparison between the first reflectance image and the second reflectance image.
