A method and system perform an ophthalmic procedure on an eye having an optical path from the lens to the retina. An image of at least part of the eye is received in a data processing unit. The image includes the optical path. The data processing unit determines keep out zone(s) and identifies undesirable feature(s) based on the image. The keep out zone(s) include the retina. The data processing unit also selects one of the undesirable feature(s) for removal. At least part of the undesirable feature is outside of the keep out zone(s). Confirmation for removal of the undesirable feature is received in the data processing unit. In response to receiving the confirmation, a control unit controls a laser to perform laser removal the at least the portion of the undesirable feature without targeting any portion of the keep out zone(s).

Systems, devices, and methods for treating a glaucomatous eye are provided. An amount of pulsed laser energy is delivered to the pars plana of the eye by a hand-holdable device which comprises a hand-holdable elongate member and a contact member disposed on an end of the elongate member. A contact surface of the contact member is placed in direct contact with the eye so that a reference edge of the contact member aligns with the limbus and a treatment axis defined by the elongate member is angularly offset from the optical axis of the eye. The amount of pulsed laser energy delivered is insufficient to effect therapeutic photocoagulation but is sufficient to increase uveoscleral outflow so as to maintain a reduction from pre-laser treatment intraocular pressure. Amounts of pulsed laser energy will be transmitted to a circumferential series of tissue regions of the eye.

A device and a method for the femtosecond laser surgery of tissue, especially in the vitreous humor of the eye. The device includes an ultrashort pulse laser with pulse widths in the range of approximately 10 fs-1 ps, especially approximately 300 fs, pulse energies in the range of approximately 5 nJ-5 μJ, especially approximately 1-2 μJ and pulse repetition rates of approximately 10 kHz-10 MHz, especially 500 kHz. The laser system is coupled to a scanner system which allows the spatial variation of the focus in three dimensions (x, y and z). In addition to the therapeutic laser/scanner optical system, the device includes a navigation system.

Surgical apparatus for performing in pars plana vitrectomy microsurgery including a cannula having an intraocular portion that connects to an infusion tube. The intraocular portion includes fenestrations at its distal end. The intraocular portion receives fluid through the infusion tube and dispenses the fluid through the fenestrations lessening the flow at an infusion site in an eye. The surgical apparatus includes a vitreous cutter having a suction tube at one end and a shaft at another end. The cutting port cuts vitreous into smaller pieces or a laser that liquefies the vitreous. The shaft receives the cut vitreous pieces and the suction tube draws out the cut vitreous pieces from the eye. The surgical apparatus includes a vitreoretinal surgical tool having a vitreoretinal cutter having a scissor-like or forceps-like mechanism. The vitreoretinal cutter holds and/or cuts a membrane in the eye during the microsurgery.

A method of treating a subject having one or more eye conditions comprises applying phacoemulsification ultrasound to a subject having one or more eye conditions; and applying an excimer laser to the subject to preventatively treat glaucoma. A system for treatment of one or more eye conditions in a subject comprises a phacoemulsification ultrasound system and an excimer laser system. The phaco system comprises an ultrasound probe for treating cataracts in the subject. The excimer laser system comprises an excimer laser and a fiber probe that applies pulsed shots of energy from the excimer laser to the eye to prophylactically treat glaucoma.

Devices and methods are disclosed for an optical component mounting system for supporting an optical component such as a laser. The mounting system comprises a first component comprising a first surface, a second component comprising a second surface facing the first surface, and adhesive between the first surface of the first component and the second surface of the second component, wherein the first component comprises at least three mounting pads extending from the first surface for contacting the second surface of the second component and providing direct support between the first component and the second component. The component comprising the mounting pads may be a lower mount, an upper mount such as an upper clamping mount, or a bonding pad or other component in the stack of components. A method of assembling the stack of components may comprise curing the adhesive at a temperature at or above an upper end of an expected temperature operating range for the optical component mounting system.

A method for re-configuring a biomedical laser device. The biomedical laser device is pre-configured to be operable in one or more operational modes, and is provided with set of operational parameters that are employed for at least one of: given medical procedure, given medical treatment, activation of given drug, illumination of given dye. The method includes collecting information indicative of light output properties of biomedical laser device measured during given operational mode; detecting deviation in measured light output properties with respect to predefined light output properties for given operational mode; determining new set of operational parameters that are to be employed for at least one of: new medical procedure, new medical treatment, activation of new drug, illumination of new dye; and sending new set of operational parameters to biomedical laser device for re-configuring biomedical laser device to be operable in a new operational mode.

The present disclosure relates to a laser probe assembly coupled to a laser system through an optical fiber cable. In one example, the laser probe assembly comprises a probe tip coupled to the probe body, the probe tip housing multiple fibers. Each of the multiple fibers comprises a proximal end that couples to the laser system and a distal end that terminates in the probe tip, a single core for transporting a laser beam provided by the laser system, and a cladding surrounding the core. The laser probe assembly also comprises a lens for projecting multiple laser beams provided by the multiple fibers on to a surgical site. Within the probe tip, parts of outer surfaces of portions of any two adjacent fibers of the multiple fibers touch. Also, the multiple fibers are at least substantially centered with respect to the lens.

The here described invention generally relates to systems for laser eye surgery. It certain embodiments it discloses systems to perform femtosecond eye surgery without docking between the laser delivery system and the patient's eye as well as certain laser delivery system configurations that allow integration of laser delivery systems into a surgical microscope in specific ways, as well as integration into a slit lamp system.
