Abstract: Systems and techniques for laser surgery are described. Scan data may be created by determining a coordinate of the object at a set of points along an arc by the imaging system, wherein the coordinate of the object is a Z coordinate of an object layer. An object shape parameter and position parameter may be determined based on the scan data by a system control module by extracting an amplitude and a phase of the scan data determining a center of the object layer based on the extracted amplitude and phase.

Abstract: An ophthalmic laser surgical system includes a pulsed laser source configured to generate a pulsed laser beam, optics configured to direct the laser beam towards a target region in a lens of an eye, and a processor configured to control the optics to form a regular array of cells in the target region by creating layers of photodisrupted bubbles to generate cell boundaries. The layers are created by causing the optics to scan the pulsed laser according to a curvature of a focal plane of the optics to track a natural curvature of the lens.

Abstract: A patient interface for an ophthalmic system can include an attachment portion, configured to attach the patient interface to a distal end of the ophthalmic system; a contact portion, configured to dock the patient interface to an eye; and a contact element, coupled to the contact portion, configured to contact a surface of a cornea of the eye as part of the docking of the patient interface to the eye, and having a central portion with a central radius of curvature Rc and a peripheral portion with a peripheral radius of curvature Rp, wherein Rc is smaller than Rp.
