A therapeutic method can include receiving an initial astigmatism condition of an eye; receiving a target final astigmatism condition of the eye; generating, based on the initial and target final astigmatism conditions, an eye incision pattern by iterating through a plurality of potential corrective combinations; and cutting the eye based on the eye incision pattern. Each of the potential corrective combinations can be defined by one or more of: an intraocular lens selected from a plurality of intraocular lens options, an access incision selected from a plurality of access incision options, and an arcuate incision selected from a plurality of arcuate incision options.

Laser pulse modulation for laser corneal treatments is used to control the thermal energy imparted to the cornea. The optical energy of the laser pulses may be modulated to reduce or increase the thermal energy, depending upon an expected thermal load or a measured temperature at each position location of the cornea subject to laser treatment. The laser pulse modulation may involve pulse frequency modulation, pulse amplitude modulation, and pulse duration modulation.

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.

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.

Devices and method for treating aqueous collector channels or tissue(s) associated with aqueous collector channels to improve or enhance outflow of aqueous humor from an eye thereby reducing intraocular pressure in the eye.

The present invention predicts prior to a laser iris color-change procedure what a patient's iris color will be after the procedure. The present invention does so by identifying and measuring a variety of anatomical features of the patient's eye that affect or are otherwise relevant to predicting the patient's post-operative iris color, translating these measurements into a post-operative iris color prediction, and communicating this prediction to the patient in a manner sufficient to manage the patient's expectations with respect to the aesthetic outcome of the procedure.

Methods of treating an eye are provided that entail partially penetrating the sclera and delivering light energy from an optical fiber within the penetration to treat the a target tissue in the eye, for example, to coagulate vasculature underlying the sclera within a planned incision area. Also provided are treatment probes for treating an eye of a patient includes an elongate body that defines a handle and an advanceable penetrating member and optical fiber housed within the elongate body. The probe is configured to advance the penetrating member so as to penetrate the sclera, only partially, and advance the treatment fiber into the penetration to deliver treatment light energy to coagulate the vasculature underlying the sclera. The probe can include one or more penetrating members and corresponding optical fibers to form one or more penetrations concurrently within the planned incision area.

Devices and methods of laser surgery of an eye, especially for refractive surgery, preferably for keratoplasty. The invention includes a planning and control unit, a system for laser surgery of an eye and a planning and control method wherein a device coordinate system of the first laser device and a device coordinate system of the characterization device are coupled using registration and measurement data or model data of the lamella can be unambiguously registered to the device coordinate systems, further by a defined edge geometry of the lamella, an ametropia correction during the generation of the lamella and by taking into account the hydration condition of the lamella, as well as methods for surgery.

The disclosure relates to systems and methods for performing eye surgery in which a single image that simultaneously presents a graphical representation of a planned or actual flap location superimposed with a graphical representation of a planned or actual area of ablation is used.

An ophthalmological device for surgical treatment of a cornea comprises a laser source, a focusing optical module, a scanner system, and an electronic circuit configured to control the scanner system to move the focus of the pulsed laser beam generated by the laser source to cut inside the cornea a lenticule, an opening incision in an exterior surface of the cornea, and two access channels which connect the opening incision to the posterior lenticule surface and to the anterior lenticule surface to provide access for a surgical tool through the opening incision to the posterior lenticule surface and the anterior lenticule surface, respectively. The access channels are cut to overlap at least partially from a top view perspective onto the cornea.
