    Abstract: The patient interface may comprise an axis for alignment with an axis of the eye such as an optical axis of the eye. The interface may comprise a guide to allow the interface to move along the axis with the eye, which can inhibit increases in intraocular pressure when the patient is aligned with the laser. The interface may comprise a lock to hold the patient interface at a location along the axis, which can maintain alignment of the patient with the laser eye surgery system. The interface may comprise a plurality of transducers to measure forces to the eye during surgery. The laser eye surgery system can be configured in one or more of many ways to respond to the measured forces. For example, the system may offset the position of laser beam pulses to increase the accuracy of the placement of the beam pulses on the eye.

    Abstract: A full depth ophthalmic surgical system includes a femtosecond laser source and an optical coherence tomographer. The system is capable of performing surgical procedures along the entire length of the eye from the cornea to the retina. In one embodiment, the system uses a removeable focal point extension assembly to extend the reach of the focal point location of the laser beam to the vitreous humor of the eye. In another embodiment, the optical system of the ophthalmic surgical system is optimized to focus the laser beam and imaging light in the vitreous humor of the eye. For procedures performed posterior to the lens, a method for calibrating the full depth ophthalmic surgical system uses the focal zone of the optical coherence tomographer beam as a proxy for the focal zone of the femtosecond laser source to. The system can be used to perform treatment in the vitreous humor, including treating floaters and liquification of the vitreous humor.

    Abstract: 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.

    Abstract: A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.

    Abstract: A patient interface includes an eye interface device, a scanner, a first support assembly, and a beam source. The eye interface device is configured to interface with an eye of a patient. The scanner is configured to be coupled with the eye interface device and operable to scan an electromagnetic radiation beam in at least two dimensions in an eye interfaced with the eye interface device. The scanner and the eye interface device move in conjunction with movement of the eye. The first support assembly supports the scanner so as to accommodate relative movement between the scanner and the first support assembly parallel so as to accommodate movement of the eye. The beam source generates the electromagnetic radiation beam. The electromagnetic radiation beam propagates from the beam source to the scanner along an optical path having an optical path length that varies in response to movement of the eye.
