Abstract
Method, apparatus and systems for laser surgery as part of cataract surgery. The implementation thereof includes: A means to perform incisions in the cornea and inside the eye. In particular Limbal Relaxating Incisions and an anterior or posterior capsulotomy/capsulorhexis using a rapid fire sequence of photodisruptive laser pulses, placed to open the capsule for cataract surgery. The system and methods provides the means to target and direct the laser pulse sequence into the desired region of the eye without the need of a patient interface that is locked to the laser delivery system and holds the eye in a fixed position relative to the delivery system.

1-41. (canceled)
A method for creating a circular incision in a capsule of a lens of an eye using photodisruptive laser pulses, with a focus spot diameter greater than 1 micrometer and smaller than 10 micrometers and a laser pulse duration shorter than 10 picoseconds, the method comprising applying the laser pulses to a capsule of the lens, without using a contacting interface between a laser system and the eye, in a rapid sequence consisting of a successive circular pattern starting posterior to a desired target plane of the capsule and scanning through the capsule and into an anterior region of the target plane, wherein a circular incision pattern is created by the sequence of laser pulses placed next to each other to form the pattern, and wherein a total laser treatment time is shorter than 1 second.
A method for creating a limbal relaxing incision in a cornea of an eye using photodisruptive laser pulses with a focus spot diameter greater than 1 micrometer and smaller than 10 micrometers and a laser pulse duration shorter than 10 picoseconds, the method comprising applying the laser pulses, without the use of a contacting interface between a laser system and the eye, in a rapid sequence such that a total laser treatment time is shorter than 1 second.
