Abstract: A measurement apparatus for measuring a laser focus spot size, which includes a two-dimensional image detector and an imaging system which forms a magnified image of a focus spot located an object plane onto the image detector. The imaging system includes at least an objective lens. A sealed liquid container is secured over a part of the objective lens such as the optical surface of the objective lens is immersed in the liquid (e.g. water) within the container. The liquid container has a window through which the laser beam enters. An image processing method is also disclosed which processes the image obtained by the image detector to obtain the focus spot size while implementing an algorithm that corrects for the effect of ambient vibration.

Abstract: A photo detector is selectively coupled to a first integrator or a second integrator with switching circuitry when the laser pulses. An integration time of the signal from the photo detector can be substantially greater than an amount of time between successive laser beam pulses in order to provide an accurate measurement of each laser beam pulse of a high repetition rate pulsed laser. The laser may comprise a clock coupled to an optical switch of the laser system, and control circuitry can control switching and coupling of the detector to the first integrator or the second integrator in response to the clock signal. The first integrator and the second integrator can be selectively coupled to an output such that the first integrator or the second integrator is coupled to the output of the energy detection circuitry when the other integrator is coupled to the detector.

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 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: In a laser cataract procedure that also corrects for astigmatism, an iris registration method compares an iris image of a patient's eye taken when the eye is not docked to a patient interface device with an iris image of the same eye that is docked to the patient interface, to calculate a rotation angle between the two images. The astigmatism axis of the eye is measured when the eye is not docked, and the measured axis is rotated by the calculated rotation angle to obtain a rotated astigmatism axis relative to the iris image of the docked eye. The laser cataract procedure is performed based on the rotated astigmatism axis. The rotation angle is calculated by optimizing a transformation that transforms the undocked iris image to match the docked iris image, where the transformation includes a dilation factor that accounts for different pupil dilation of the two iris images.

Abstract: A counterbalance mechanism in an ophthalmic laser system balances the weight of the laser beam delivery head and provides small, precise and repeatable variations in the net load exerted by the laser head on the patient's eye over a defined distance of travel. The counterbalance mechanism includes a balance beam pivotably mounted on a support block, with the laser head and a counterweight mounted on its two ends. The counterweight is movable along the balance beam via a linear motion bearing. A mechanical link links the counterweight to the support block; the link has a predefined length and is pivotable around its respective connection points on the support block and the counterweight. When the balance beam pivots, the link causes the counterweight to move along the balance beam, thereby changing the mechanical advantage of the counterweight and varies the counterbalancing force to provide variations in the net load.

Abstract: A laser eye surgery system includes a laser source, a ranging subsystem, an integrated optical subsystem, and a patient interface assembly. The laser source produces a treatment beam that includes a plurality of laser pulses. The ranging subsystem produces a source beam used to locate one or more structures of an eye. The ranging subsystem includes an optical coherence tomography (OCT) pickoff assembly that includes a first optical wedge and a second optical wedge separated from the first optical wedge. The OCT pickoff assembly is configured to divide an OCT source beam into a sample beam and a reference beam. The integrated optical subsystem is used to scan the treatment beam and the sample beam. The patient interface assembly couples the eye with the integrated optical subsystem so as to constrain the eye relative to the integrated optical subsystem.

Abstract: Method and apparatus for performing a laser-assisted posterior capsulotomy and for performing laser eye surgery on an eye having a penetrated cornea are provided. A method for performing a posterior capsulotomy includes injecting fluid between the lens posterior capsule and the anterior hyaloids membrane to separate the lens posterior capsule and the anterior hyaloids membrane. With the lens posterior capsule separated from the anterior hyaloids membrane, a posterior capsulotomy is performed on the lens posterior capsule by using a laser to incise the lens posterior capsule.

Abstract: A first image of the eye is generated when the cornea of the eye is exposed to a gas. The cornea is covered with an optic of a patient interface. A second image of the eye with the patient interface over the cornea is generated. In this second image, the patient interface distorts the second image of the eye. One or more of a position or an orientation of the eye is determined in response to the first image and the second image when the patient interface has been placed over the cornea.
