    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: 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. 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: A laser surgery system includes a light source, an eye interface device, a scanning assembly, a confocal detection assembly and preferably a confocal bypass assembly. The light source generates an electromagnetic beam. The scanning assembly scans a focal point of the electromagnetic beam to different locations within the eye. An optical path propagates the electromagnetic beam from a light source to the focal point, and also propagates a portion of the electromagnetic beam reflected from the focal point location back along at least a portion of the optical path. The optical path includes an optical element associated with a confocal detection assembly that diverts a portion of the reflected electromagnetic radiation to a sensor. The sensor generates an intensity signal indicative of intensity the electromagnetic beam reflected from the focal point location. The confocal bypass assembly reversibly diverts the electromagnetic beam along a diversion optical path around the optical element.

    Abstract: A method of treating a cataractous lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern, delivering the treatment pattern to the lens of the patient's eye to create a plurality of cuts in the form two or more different incisions patterns within the lens to segment the lens tissue into a plurality of patterned pieces, and mechanically breaking the lens into a plurality of pieces along the cuts. A first incision pattern includes two or more crossing cut incision planes. A second incision pattern includes a plurality of laser incision each extending along a first length between a posterior and an anterior surface of the lens capsule.

    Abstract: An OCT system for imaging multiple depth positions includes a light source, a sample arm and two or more reference arms. The sample arm propagates light to the object and directs object return light having a first return light beam from a first position and a second return light beam from a second position, the second return light having a dispersion level higher than the first return light beam by a dispersion difference amount. The first and second reference arms produce light beams having substantially the same dispersion as the first and second return light beams, respectively. The optical pathway combines all of the object return light and the reference light beams. An OCT detector measures the resulting interferogram. Imaging information is obtained for both the first position and the second position based on the dispersion difference amount.

    Abstract: The XYZ beam position of an ophthalmic laser system is calibrated by measuring a fluorescent signal induced by the focused laser beam in a thin glass coverslip via multiphoton absorption. A video camera measures the XY position and intensity of the fluorescent signal as the focused laser beam strikes the coverslip. The Z position of the focus is determined by scanning the targeted z position and identifying the Z scanner position of peak fluorescence. An OCT system measures the real space Z location of the coverslip, which is correlated with the Z scanner position. Other laser system parameters are assessed by repeatedly scanning a lower energy laser beam in a piece of IOL material, and observing damage (scattering voids) formation in the IOL material. Based on the rate of damage formation, laser system parameters such as beam quality, numerical aperture, pulse energy, and pulse duration, etc. can be assessed.
