An actuation of the actuation lever may gradually straighten the flexible housing tube and the optic fiber.

The present invention relates to an ophthalmic treatment device and a method for operating the same. The present invention provides an ophthalmic treatment device and a method for operating the same, the ophthalmic treatment device comprising: a treatment beam generation unit for generating a treatment beam; a beam delivery unit for forming a path along which the treatment beam generated from the treatment generation unit is delivered to a treatment area positioned on the fundus; a monitoring unit for emitting a detecting beam along the path of delivery of the treatment beam and sensing treatment area state information on the basis of information regarding a change in speckle of the detecting beam, which is scattered and reflected from the treatment area; and a control unit for controlling the driving of the treatment beam generation unit on the basis of the treatment area state information sensed by the monitoring unit.

A method of scanning a laser beam across a set of cells includes during a first interval, scanning a laser beam across a set of cells; and during a second interval, deflecting the laser beam away from the set of cells. The first interval is selected to cause microcavitation in at least a portion of the cells from the set of cells.

The present disclosure relates to a fiber and a laser probe assembly with a probe tip that houses the fiber. In certain aspects, the fiber includes a core, an outer cladding surrounding the core, and an end face at a proximal and/or distal end of the fiber. The core is configured to transmit a laser light beam while the core and the outer cladding are both configured to transmit an illumination light. In certain aspects, a surface area of the end face corresponding to a cross-section of at least the outer cladding is treated with a roughening or polishing process to modulate an illumination light output angle of the fiber. Using a fiber that is configured to transmit a laser light beam as well as a wide-angle illumination light allows for a more compact fiber and probe tip, allowing for medical procedures that require a narrower probe.

A steerable laser probe may include a handle having a handle distal end and a handle proximal end, a plurality of actuation controls of the handle, a flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end, and an optic fiber disposed within an inner bore of the handle and the flexible housing tube. An actuation of an actuation control of the plurality of actuation controls may gradually curve the flexible housing tube. A gradual curving of the flexible housing tube may gradually curve the optic fiber. An actuation of an actuation control of the plurality of actuation controls may gradually straighten the flexible housing tube. A gradual straightening of the flexible housing tube may gradually straighten the optic fiber.

The present invention relates to an ophthalmic treatment device and a method of operating same, and provides an ophthalmic treatment device and a method of operating same, the device comprising: a treatment beam generating unit for generating a treatment beam; a beam delivery unit for forming a path through which the treatment beam generated by the treatment beam generating unit travels to a treatment region disposed in a fundus; a monitoring unit for irradiating a detecting beam along the path through which the treatment beam travels, and detecting information of the state of the treatment region based on interference information on the detecting beam reflected from the treatment region; and a controller for controlling the operation of the treatment beam generating unit based on information on the state of the treatment region detected by the monitoring unit.

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 steerable laser probe may include a handle, an actuation structure having an actuation structure distal end and an actuation structure proximal end, a housing tube, a first housing tube portion of the housing tube having a first stiffness, a second housing tube portion of the housing tube having a second stiffness, and an optic fiber disposed within an inner bore of the handle and the housing tube. An extension of the actuation structure distal end relative to the actuation structure proximal end may be configured to gradually curve the housing tube and the optic fiber. A retraction of the actuation structure distal end relative to the actuation structure proximal end may be configured to gradually straighten the housing tube and the optic fiber.

A steerable laser probe may include a handle having a handle proximal end and a handle distal end, an actuation structure of the handle, a housing sleeve, a shape memory sleeve at least partially disposed within the housing sleeve, and an optic fiber disposed within the shape memory sleeve and within an inner bore of the handle. A compression of the actuation structure may be configured to gradually curve the optic fiber. A compression of the actuation structure may be configured to gradually straighten the optic fiber. A decompression of the actuation structure may be configured to gradually curve the optic fiber. A decompression of the actuation structure may be configured to gradually straighten the optic fiber.
