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.

Abstract: Embodiments of this invention relate to systems and methods for automatic depth (or Z) detection before, during, or after laser-assisted ophthalmic surgery. When performing ophthalmic laser surgery, the operator (or surgeon) needs to make accurate and precise incisions using the laser beam. With the automatic depth detection systems and methods, the same laser used for the surgical procedure may be used for depth measurement of the surgical incisions. The surgical laser system may include a laser delivery system for delivering a pulsed laser beam to photoalter an eye, a mirror to transmit at least a portion of reflected light of the pulsed laser beam, a lens positioned to focus the transmitted reflected lighted on to a detector, (such as a CCD), and a depth encoder configured to automatically detect depth according to one or more of color, intensity, or shape of the focused spot on the CCD.

Abstract: Systems and methods for locating the center of a lens in the eye are provided. These systems and methods can be used to improve the effectiveness of a wide variety of different ophthalmic procedures. In one embodiment, a system and method is provided for determining the center of eye lens by illuminating the eye with a set of light sources, and measuring the resulting first image of the light sources reflected from an anterior surface of the lens and the resulting second image of the light sources reflected from a posterior surface of the lens. The location of the center of the lens of the eye is then determined using the measurements. In one embodiment, the center of the lens is determined by interpolating between the measures of the images. Such a determination provides an accurate location of the geometric center of the lens.

Abstract: A method implemented in an ophthalmic laser system to perform iris registration based on two iris images taken with the patient at upright and supine positions, respectively. For each iris image, the iris region is transformed into a rectangular rubbersheet, with the radial and angular coordinates of the iris image respectively mapped to vertical and horizontal coordinates of the rubbersheet. A horizontal one-dimensional log-Gabor transform is applied to the rubbersheet line-by-line. The transformed rubbersheet is binarized line-by-line. The two binary rubbersheets are compared at a series of relative horizontal shifts to determine the horizontal shift value that produces the lowest Hamming distance between the two binary rubbersheets, and the cyclotorsion rotation of the eye between the upright and supine positions is calculated accordingly. Then, while the patient is in the supine position, the laser system treats the eye based on measured astigmatism axis orientation and the calculated cyclotorsion rotation.
