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 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.

A method for cataract surgery on an eye of a patient includes scanning a first focus position of a first pulsed laser beam at a first pulse energy in a first scanning pattern to photodisrupt a tissue structure of a lens with a plurality of pulses of the first laser beam to form one or more cuts within the lens, the cuts being short of reaching a side edge of the lens and being configured to divide the lens into two or more segments which are attached to each other in regions adjacent the side edge of the lens; and afterwards, completely separating the two or more segments of the lens from each other by scanning a second focus position of a second pulsed laser beam having a second pulse energy higher than the first pulse energy in a second scanning pattern that is co-registered to the first scanning pattern.

System and method for plasma-mediated modification of tissue

A system for treating a cataractous lens of a patient's eye includes a laser source for generating a light beam, a scanning system for deflecting the light beam to form a treatment pattern of the light beam, and a controller operably coupled to the laser source and scanning system and configured to operate the scanner to form the treatment pattern. The treatment pattern is a plurality of cuts in the form two or more different incision patterns for segmenting the lens tissue into a plurality of patterned pieces. The incision pattern includes: a first incision pattern including two or more crossing cut incision planes; and a second incision pattern comprising one or more laser incision each extending along a first length between a posterior and an anterior surface of the lens capsule.

A water jet instrument may be used for manually performing eye surgery such as, cataract, or perform micro-surgery (remove cartilage), or any emulsification technique. The water jet instrument may be manually controlled or controlled by a system with a robotic control. The water jet apparatus defines a jet cutting area that is based at least in part on a flow rate meter and a feedback loop.

A method for cataract surgery on an eye of a patient includes scanning a first focus position of a first pulsed laser beam at a first pulse energy of between one-half microjoule and 50 microjoules in a first scanning pattern to photodisrupt a first tissue structure portion with a plurality of pulses of the first laser beam to form an incised surface; and afterwards, scanning a second focus position of a second pulsed laser beam having a second pulse energy being between 50 microjoules and 5,000 microjoules in a second scanning pattern that is co-registered to the first scanning pattern to further photodisrupt the same first tissue structure portion with the second laser beam to further separate segments of the first tissue structure along the incised surface.

A system for cataract surgery on an eye of a patient is described. In one embodiment, the system comprises a first laser source configured to deliver a first laser beam in a pulsed form at a first pulse energy; a second laser source configured to deliver a second laser beam in a pulsed form at a second pulse energy greater than the first pulse energy; an scanning optical system, configured to: receive the first and second laser beams; and adjust a first focus position of the first laser beam, and a second focus position of the second laser beam, in up to three dimensions to direct the first and second laser beams onto one or more targeted tissue structure portions of the eye of the patient; a controller operatively coupled to the scanning optical system and configured to cause the scanning optical system to adjust the first focus position to photodisrupt a first tissue structure portion with the first laser beam, and subsequently adjust the second focus position to further photodisrupt the first tissue structure portion with the second laser beam.

A lid speculum that operates in an anatomically correct manner. The speculum has a first blade and a second blade that can pivot about an axis of rotation. The speculum is constructed so that the axis of rotation is essentially parallel with and posterior to a line that intersects a medial canthi and lateral canthi of an eye. With such an arrangement the blades will move in a radial manner that corresponds to the shape of the globe. This movement tends to lessen kinked pressure points in the eyelid.

3-dimensional lid speculum and method for use

An ultrasonically driven phaco tip and an interocular procedure for emulsifying a lense of an eye. The tip includes a flat distal end which has a pair of adjacent shoulders. The flat end creates a more efficient cutting surface. The shoulders provide a relatively large surface area that focuses ultrasonic pressure waves into the bubbles of an irrigation fluid that surrounds the tip. The focused pressure waves induce cavitation within the fluid and emulsification of the lense tissue. A lense may be emulsified by inserting the phaco tip into the anterior chamber of an eye and sculpting a bowl in the center of the lense. The tip is then rotated to a vertical position and used to cut a groove in the lense. The groove may be widen by another pass of the phaco tip so that the tip and a splitting instrument can be inserted into the widen groove. The tip and instrument are then pulled in opposite directions to crack the lense. Alternatively, the lense can be cracked by merely rotating the phaco tip while the tip is within the groove. The process of cutting grooves and cracking the lense is repeated to create a number of small lense fragments. The tip is then rotated to a horizontal position to emulsify and aspirate the lense tissue.
