Abstract: A method of treating a lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern of the light beam, delivering the treatment pattern to the lens of a patient's eye to create a plurality of cuts in the lens in the form of the treatment pattern to break the lens up into a plurality of pieces, and removing the lens pieces from the patient's eye. The lens pieces can then be mechanically removed. The light beam can be used to create larger segmenting cuts into the lens, as well as smaller softening cuts that soften the lens for easier removal.

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 method of accommodating patient movement in a laser surgery system with a scanner. The scanner is configured to be coupled with an 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. A 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. A 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.

The system is capable of performing surgical procedures along the entire length of the eye from the cornea to the retina. 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. In some embodiments, the system includes a video camera with a tunable lens before it to image the entire length of the eye. For procedures performed posterior to the lens, a method for calibrating the full depth ophthalmic surgical system is also provided. 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: Methods and related apparatus for real-time process monitoring during laser-based refractive index modification of an intraocular lens. During in situ laser treatment of the IOL to modify the refractive index of the IOL material, a signal from the IOL is measured to determine the processing effect of the refractive index modification, and based on the determination, to adjust the laser system parameters to achieve intended processing result. The signal measured from the IOL may be a fluorescent signal induced by the treatment laser, a fluorescent signal induced by an external illumination source, a temporary photodarkening effect, a color change, or a refractive index change directly measured by phase stabilized OCT.

The system is capable of performing surgical procedures along the entire length of the eye from the cornea to the retina. 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. In some embodiments, the illumination light source and the scanning mirrors are imaged by the system's objective lens and the patient interface lens to locations near the pupil, to increase the volume of the vitreous humor reachable by the illumination light and laser beam. For procedures performed posterior to the lens, a method for calibrating the full depth ophthalmic surgical system is also provided. The system can be used to perform treatment in the vitreous humor, including treating floaters and liquification of the vitreous humor.

Abstract: An imaging system includes an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The eye interface device interfaces with an eye. The scanning assembly supports the eye interface device and scans a focal point of an electromagnetic radiation beam within the eye. The beam source generates the electromagnetic radiation beam. The free-floating mechanism supports the scanning assembly and accommodates movement of the eye and provides a variable optical path for the electronic radiation beam and a portion of the electronic radiation beam reflected from the focal point location. The variable optical path is disposed between the beam source and the scanner and has an optical path length that varies to accommodate movement of the eye. The detection assembly generates a signal indicative of intensity of a portion of the electromagnetic radiation beam reflected from the focal point location.

Abstract: Apparatus to treat an eye with an ophthalmic laser system comprises a patient interface having 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. Liquid is added above the eye to act as a transmissive medium. A coupling sensor is coupled to the suction line to determine coupling of the retention structure to the eye. A separate pressure monitoring circuit having a much smaller volume than the suction line is connected to the annular retention structure to measure suction pressure therein. A system processor coupled to the monitoring pressure sensor includes instructions to interrupt firing of a laser when the pressure measured with a monitoring pressure sensor rises above a threshold amount.
