Methods are disclosed comprising measuring, with a first scanner, a central part of the visual image, measuring, with a second scanner, a peripheral part of the visual image, calculating, by a processor, a pan-retinal measure of image contrast for an extended area of the retina, and optimizing a pan-retinal visual quality. Methods further comprising optimizing a pan-retinal visual quality are also disclosed. Systems are also disclosed comprising either a scanner or a laser, a non-transitory memory having instructions that, in response to an execution by a processor, the processor receives a first measurement of the central part of the visual image, receives a second measurement of the peripheral part of the visual image, and calculates a pan-retinal measure of image contrast for an extended area of the retina. Methods of manufacturing lenses, including contact lenses are disclosed.

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.

A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

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.

A planning device for generating control data, a treatment apparatus for refraction correction eye surgery and a method for generating control data for such a treatment apparatus which allows an improved subsequent refraction correction. The planning device includes a calculation processor for defining a cut surface of the cornea for post-treatment, wherein the calculation device is designed such that a change of thickness of the epithelium is taken into account in the calculation, which was caused essentially by a pretreatment.

Technologies are generally described for customization of treatment based on dosimetric data collected during the treatment. In some examples, a laser treatment procedure may involve the application of multiple laser pulses to a treatment site. During the laser treatment procedure, an effect resulting from the application of one or more of the laser pulses may result in dosimetric data, such as acoustic and/or optical data. The dosimetric data may then be used to determine the efficacy of the laser treatment procedure and/or to adjust, in real-time, a remainder of the laser treatment procedure.

Embodiments of this invention generally relate to ophthalmic laser procedures and, more particularly, to systems and methods for lenticular laser incision. In an embodiment, an ophthalmic surgical laser system comprises a laser delivery system for delivering a pulsed laser beam to a target in a subject's eye, an XY-scan device to deflect the pulsed laser beam, a Z-scan device to modify a depth of a focus of the pulsed laser beam, and a controller configured to form a top lenticular incision and a bottom lenticular incision of a lens in the subject's eye, where each of the top and bottom lenticular incision includes a center concave portion and an edge transition portion that has a smooth convex shape and is smoothly joined to the center concave portion.

A method for modifying a refractive property of ocular tissue in an eye by creating at least one optically-modified gradient index (GRIN) layer in the corneal stroma and/or the crystalline by continuously scanning a continuous stream of laser pulses having a focal volume from a laser having a known average power along a continuous line having a smoothly changing refractive index within the tissue, and varying either or both of the scan speed and the laser average power during the scan. The method may further involve determining a desired vision correction adjustment, and determining a position, number, and design parameters of gradient index (GRIN) layers to be created within the ocular tissue to provide the desired vision correction.

The disclosure provides a system that may acquire, via an image sensor, an image of an eye of a person; may determine a location of an iris of the eye from the image; may determine a position of a suction ring from the image; may display, via a display, the image; may display, via the display, a first graphic overlay on the image that indicates the location of the iris of the eye; may display, via the display, a second graphic overlay on the image that indicates the position of the suction ring; may determine multiple iris structures from the image; may determine an orientation of the eye based at least on the multiple iris structures from the image; and may display, via the display, information that indicates the orientation of the eye.
