Apparatus for patterned plasma-mediated laser ophthalmic surgery

摘要

A system for ophthalmic surgery on an eye includes: a pulsed laser which produces a treatment beam; an OCT imaging assembly capable of creating a continuous depth profile of the eye; an optical scanning system configured to position a focal zone of the treatment beam to a targeted location in three dimensions in one or more floaters in the posterior pole. The system also includes one or more controllers programmed to automatically scan tissues of the patient's eye with the imaging assembly; identify one or more boundaries of the one or more floaters based at least in part on the image data; iii. identify one or more treatment regions based upon the boundaries; and operate the optical scanning system with the pulsed laser to produce a treatment beam directed in a pattern based on the one or more treatment regions.

1. A laser surgical system for making incisions in ocular tissues during a cataract surgical procedure, the system comprising:
a laser system comprising a scanning assembly; a laser operable to generate a laser beam configured to incise ocular tissue; an imaging device configured to acquire image data of at least a portion of the crystalline lens; and a control system operably coupled to the laser system and configured to:
operate the imaging device to acquire image data;identify one or more treatment targets based in part of the image data;operate the scanning assembly to position a focal zone of the laser beam at a predetermined position in the ocular tissue;prior to scanning the target tissue at the predetermined position, operate the imaging device to generate image data and process the image data to determine whether the one or more treatment targets is located at the predetermined position; andif the one or more targets is at the predetermined position, operate the laser and the scanning assembly to scan the focal zone of the laser beam in a treatment scanning pattern, wherein positioning of the focal zone in the treatment scanning pattern is determined in part by the control system based on the image data.
