Abstract
Systems, devices and methods are provided to deliver microporation medical treatments to improve biomechanics, wherein the system includes a laser for generating a beam of laser radiation on a treatment-axis not aligned with a patient's visual-axis, operable for use in subsurface ablative medical treatments to create an array pattern of micropores that improves biomechanics. The array pattern of micropores is at least one of a radial pattern, a spiral pattern, a phyllotactic pattern, or an asymmetric pattern.
Core Innovation
The invention provides a system and method for delivering microporation medical treatments to improve biomechanics using an ocular laser scleral microporation approach. A laser generates a beam of laser radiation on a treatment-axis not aligned with a patient's visual-axis to create an array pattern of micropores in a subsurface ablative medical treatment. The array pattern of micropores improves biomechanics and is formed by a controlled pattern of micropores in connective tissue zones of the sclera.
The micropore array is constrained to a defined spatial geometry selected from a radial pattern, a spiral pattern, a phyllotactic pattern, or an asymmetric pattern. The array pattern has a controlled asymmetry that is an at least partial rotational asymmetry about the center of the array pattern and extends to at least 51 percent of the micropores of the array pattern.
The system and method incorporate automated off-axis subsurface anatomy tracking, measuring, and avoidance for application of the treatment beam based on monitoring an eye position. A controller controls dosimetry of the beam of laser radiation in application to a target tissue, and a lens focuses the beam onto the target tissue.
Claims Coverage
The document includes two independent claims covering a system and a method for delivering microporation medical treatments to improve biomechanics using an off-axis laser. Across the independent claims, the coverage centers on defined micropore array geometries with controlled rotational asymmetry extending to a specified fraction of micropores, together with automated off-axis subsurface anatomy tracking, controller-controlled dosimetry, and lens focusing.
Off-axis treatment-axis microporation system for biomechanics improvement
A system comprising a laser for generating a beam of laser radiation on a treatment-axis not aligned with a patient's visual-axis, operable for use in subsurface ablative medical treatments to create an array pattern of micropores that improves biomechanics; a housing; a controller within the housing, in communication with the laser and operable to control dosimetry of the beam of laser radiation in application to a target tissue; a lens operable to focus the beam of laser radiation onto a target tissue; and an automated off-axis subsurface anatomy tracking, measuring, and avoidance system.
Controlled rotationally asymmetric micropore array geometry in an off-axis method
A method comprising generating, by a laser, a treatment beam on a treatment-axis not aligned with a patient's visual-axis in a subsurface ablative medical treatment to create an array of micropores that improves biomechanics; controlling, by a controller in electrical communication with the laser, dosimetry of the treatment beam in application to a target tissue; focusing, by a lens, the treatment beam onto the target tissue; and monitoring, by an automated off-axis subsurface anatomy tracking, measuring, and avoidance system, an eye position for application of the treatment beam.
Radial/spiral/phyllotactic/asymmetric micropore array with controlled asymmetry extent
The array pattern of micropores is at least one of a radial pattern, a spiral pattern, a phyllotactic pattern, or an asymmetric pattern, and the array pattern of micropores has a controlled asymmetry which is an at least partial rotational asymmetry about the center of the array pattern and extends to at least 51 percent of the micropores of the array pattern.
Overall claim coverage is anchored by off-axis subsurface ablative microporation using an off-axis treatment-axis not aligned with the visual-axis, combined with controller-controlled dosimetry, lens focusing, and automated off-axis subsurface anatomy tracking. Both independent claims require micropore array geometries limited to radial, spiral, phyllotactic, or asymmetric patterns, and further require controlled rotational asymmetry extending to at least 51 percent of micropores.
