Abstract: System and method for generating patterns P of aiming and treatment light on target eye tissue (e.g. the retina) of a patient's eye. The system includes light sources for treatment and aiming light, a scanner for generating patterns of spots of the generated light, a controller, and a graphic user interface that allows the user to select one of several possible spot patterns, adjust the spot density and/or spot size, and apply patterns with fixed or varied density. The patterns can be formed of interlaced sub-patterns and/or scanned without adjacent spots being consecutively formed to reduce localized heating. Partially or fully enclosed exclusion zones within the patterns protect sensitive target tissue from exposure to the light.

Abstract: 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.

Abstract: The invention relates to a method for providing control data for presbyopia reversion for an ophthalmological laser (12) of a treatment apparatus (10). As steps, the method includes determining (S10) presbyopia correction data for presbyopia correction of a cornea (16), wherein an originally uniform visual acuity of the cornea (16) is changed into multifocal areas by application of the presbyopia correction data, wherein the presbyopia correction data is stored in a database (24); retrieving (S12) the stored presbyopia correction data of the cornea (16) from the database (24), if the multifocal areas of the cornea (16) are to be adapted or cancelled at a subsequent point of time; determining (S14) control data for adapting or cancelling the multifocal areas depending on the retrieved presbyopia correction data; and providing (S16) the control data for controlling the ophthalmological laser (12) of the treatment apparatus (10).

Abstract: Rather than rely solely upon pupillary occlusion or tracking of eye movement to protect the fundus from accidental exposure to electromagnetic radiation, the present invention also utilizes an electromagnetic radiation pathway with a profile such that the energy density at the iris is greater than the energy density at the posterior portion of the eye. This disparity in energy density allows for efficacy at the anterior iris treatment site, without injury to the fundus.
