Methods and apparatus are configures to measure an eye without contacting the eye with a patient interface, and these measurements are used to determine alignment and placement of the incisions when the patient interface contacts the eye. The pre-contact locations of one or more structures of the eye can be used to determine corresponding post-contact locations of the one or more optical structures of the eye when the patient interface has contacted the eye, such that the laser incisions are placed at locations that promote normal vision of the eye. The incisions are positioned in relation to the pre-contact optical structures of the eye, such as an astigmatic treatment axis, nodal points of the eye, and visual axis of the eye.

A method of treating glaucoma in an eye includes obtaining a surgical instrument having a cutting means and severing/cleaving an anterior attachment of a portion of trabecular meshwork of the eye proximate to Schwalbe's line with the cutting means while leaving the ciliary muscle tendons attached to the scleral spur of the portion of trabecular meshwork to create a trabecular meshwork leaflet. The surgical instrument including the cutting means is preferably a handheld microsurgical cutting instrument having at least one sharpened edge. Alternatively, the instrument may be an invasive or non-invasive laser cutting instrument with a laser cutting means; a vibratory cutting instrument with a vibratory cutting means; or a thermal cutting instrument with a thermal cutting means. The step of severing the portion of trabecular meshwork is preferably characterized by a linear cleavage plane severing the attachment portion without removing substantially any trabecular meshwork from the eye.

Non-handed integrated laser-ultrasound, including femto-phaco, systems.

A system includes a laser system and a controller. The laser system includes a laser configured to emit electromagnetic radiation in laser pulses. The controller is configured to obtain an indication of an interworking control scheme for communicating with the laser system. The controller is also configured to receive inputs from an input device. The controller is further configured to communicate with the laser system for control of the laser based on the inputs and according to the interworking control scheme.

Transcorneal and fiberoptic laser delivery systems and methods for the treatment of eye diseases wherein energy is delivered by wavelengths transparent to the cornea to effect target tissues in the eye for the control of intraocular pressure in diseases such as glaucoma by delivery systems both external to and within ocular tissues. External delivery may be affected under gonioscopic control. Internal delivery may be controlled endoscopically or fiberoptically, both systems utilizing femtosecond laser energy to excise ocular tissue. The femtosecond light energy is delivered to the target tissues to be treated to effect precisely controlled photodisruption to enable portals for the outflow of aqueous fluid in the case of glaucoma in a manner which minimizes target tissue healing responses, inflammation and scarring.

In one or more embodiments, a system configured to create a fragmentation pattern in the crystalline lens of an eye includes a laser system and a computer system. The laser system directs a laser beam towards the crystalline lens. The laser system has a z-axis and xy-planes orthogonal to the z-axis. The computer system instructs the laser system to direct the laser beam toward the crystalline lens to create a star pattern to segment the crystalline lens. The star pattern at one or more xy-planes has includes a star. The star comprises an isotoxal star with a central polygon and acute vertices. The central polygon has three or more sides. Each acute vertex forms a triangular area with a side of the central polygon to yield a plurality of triangular areas.

Cataract surgery is in recent years more and more augmented and supported by the application of laser cuts in the eye tissue. Such laser systems are separate units from the phacoemulsification system units that are usually used for cataract extraction. The laser systems require the patient to be positioned under the laser unit and then being moved under the surgical microscope next to the phacoemulsification unit. The here described invention relates to systems combining several aspects of the laser system and the phacoemulsification system. In particular, this invention relates to combining at least some parts of the control system and the housing for both systems and thereby minimizing and optimizing setup time, operating room footprint, patient flow and cost. Furthermore the here disclosed invention relates to integrating the laser system under the surgical microscope and thereby significantly reducing the surgery setup and complexity.
