An apparatus includes a laser source and a scanner. The laser source is configured to generate electromagnetic radiation. The scanner scans at least part of a limbal area of an eye with the electromagnetic radiation generated by the laser source, thereby directing the electromagnetic radiation through an entire thickness of the limbal area of the eye without any contact with the eye and irradiating one or more regions of a trabecular meshwork of the eye with the electromagnetic radiation.

A device for irradiating ocular tissue, including a source of electromagnetic radiation; a beacon scattering the electromagnetic radiation transmitted through an opacity in ocular tissue so as to form scattered electromagnetic radiation; a modulator transmitting output electromagnetic radiation having a field determined from a recording of the scattered electromagnetic radiation transmitted through the opacity, so that the output electromagnetic radiation is transmitted through the opacity to the beacon. The device can be used to treat amblyopia or correct optical aberrations in corneal or lens tissue.

A system that provides neuroprotection or neuroregeneration to biological tissue includes a pulsed energy having energy parameters including a wavelength or frequency, a duty cycle and a pulse train duration. A delivery device applies the pulsed energy to neural elements of the target tissue having a chronic progressive disease or at risk of having a chronic progressive disease. The delivery device applies the pulsed energy for a predetermined total pulse train duration such that the target tissue temperature is raised sufficiently to provide neuroprotection or neuroregeneration to the neural elements of the target tissue, while maintaining the average temperature rise of the target tissue at or below a predetermined level so as not to permanently damage the target tissue.

A process that provides protective therapy for biological tissues or fluids includes applying a pulsed energy source to a target tissue or a target fluid having a chronic progressive disease or a risk of having a chronic progressive disease to therapeutically or prophylactically treat the target tissue or target fluid. The pulsed energy source has energy parameters selected so as to raise the target tissue or bodily target fluid temperature up to a predetermined temperature for a short period of time to achieve a therapeutic or prophylactic effect, while the average temperature rise of the target tissue or target fluid over a longer period of time is maintained at or below a predetermined level so as not to permanently damage the target tissue or target fluid.

A process for preventing or treating myopia includes applying a pulsed energy, such as a pulsed laser beam, to tissue of an eye having myopia or a risk of having myopia. The source of pulsed energy has energy parameters including wavelength or frequency, duty cycle and pulse train duration, which are selected so as to raise an eye tissue temperature up to eleven degrees Celsius to achieve therapeutic or prophylactic effect, such as stimulating heat shock protein activation in the eye tissue. The average temperature rise of the eye tissue over several minutes is maintained at or below a predetermined level so as not to permanently damage the eye tissue.

A system for processing a portion in a processing volume of a transparent material by application of focused radiation including a device for generating and an optical system for focusing radiation, with a device for changing the position of the focus of the radiation and a control device. The system includes a controller that controls the ophthalmologic therapy system. The controller is encoded with a scan pattern. The scan pattern includes adjacent strokes with each adjacent stroke having an angle of inclination (α) to the beam axis; and the angle of inclination (α) of the strokes to the beam axis is always larger than or equal to the focal angle (φ) of the focused radiation.

A system for processing a portion in a processing volume of a transparent material by application of focused radiation including a device for generating and an optical system for focusing radiation, with a device for changing the position of the focus of the radiation and a control device. This system performs a slow scanning movement of the focus and an independent fast scanning movement of the focus which section can be moved by the slow scanning movement in the entire processing volume in an arbitrary direction; as well as by a system into which a scan pattern is encoded, with scanning movement including at least one lateral base component in the x- and/or y-direction, which is superimposed by components with synchronous change-of-direction-movements in the z-direction and in x-direction and/or y-direction. The invention also includes corresponding methods, a control program product and a planning unit.

A process for heat treating biological tissue includes providing a plurality of energy emitters formed into an array. Treatment energy in the form of ultrasound energy is generated from the plurality of emitters and applied to target tissue. The treatment energy has energy and application parameters selected so as to raise the target tissue temperature sufficiently to create a therapeutic effect while maintaining an average temperature of the target tissue over several minutes at or below a predetermined temperature so as not to destroy or permanently damage the target tissue.

In a laser delivery system for an ophthalmic laser surgery system, a laser beam scanner employs a single or two MEMS micromirror arrays. Each micromirror in the array is capable of being independently actuated to rotate to desired angles. In one embodiment, one or two micromirror arrays are controlled to scan a laser beam in two directions. In another embodiment, a micromirror array is controlled to both correct optical aberrations in the laser beam and scan the laser beam in two directions. In yet another embodiment, a micromirror array is controlled to cause the laser beam to be focused to multiple focal spots simultaneously and to scan the multiple focal spot simultaneously. The ophthalmic laser surgery system also includes an ultrashort pulse laser, a laser energy control module, focusing optics and other optics, and a controller for controlling the laser beam scanner and other components of the system.

A retinal phototherapy or photostimulation system includes a laser console generating at least one treatment beam having parameters to photostimulate or treat, while not permanently damaging, a retinal target tissue. The parameters of the at least one treatment beam are fixed so as not to be alterable by a medical provider. A projector or camera projects the at least one treatment beam onto at least a portion of the retina, and a scanning mechanism controllably directs the at least one treatment beam to treatment areas of the retina.
