Ophthalmic treatment device, system, and method of use
Ophthalmic treatment systems and methods of using the systems are disclosed. The ophthalmic treatment systems include (a) a light source device; (b) at least one optical treatment head operatively coupled to the light source device, comprising a light source array, and providing at least one treatment light; and (c) a light control device, which (i) provides patterned or discontinuous treatment light projection onto an eye (e.g., the cornea and/or sclera of an eye); or (ii) adjusts intensity of part or all of the light source array, providing adjusted intensity treatment light projection onto an eye (e.g., the cornea and/or sclera of an eye). The at least one treatment light promotes corneal and/or scleral collagen cross-linking.
OPHTHALMIC LASER TREATMENT SYSTEM AND METHOD
An ophthalmic laser treatment system and method providing for a liquid optical interface (LOI) with a patient eye surface (PES) using an elliptical ocular suction ring (OSR) is disclosed. A disposable ocular patient interface (OPI) provides for simultaneous differential vacuum mating of the PES, OSR, OPI, and an optical window retainer (OWR). The PES, OSR, OPI, and OWR form an enclosed volume in which liquid may be interjected to cover the PES during laser treatment. A vacuum suction pump (VSP) provides controlled vacuum to the OPI ensuring proper differential vacuum mating (DVM) between the PES, OSR, OPI, and OWR during laser treatment. The OWR connects to a laser objective bracket (LOB) via an ocular force sensor (OFS) and an optical separator bracket (OSB). The OFS senses applied pressure to the PES and provides data to a computerized control device (CCD) that limits applied pressure to the PES during laser treatment.
Laser therapy system for noninvasive correction of the refractive system of the eye
The present invention refers to a Laser therapy system and a method for a treatment of a cornea and/or sclera of an eye to correct its refractive system, comprising: a dispenser for a photosensitizer agent; a 3D imaging unit; an image processing unit adapted to recognize a first collagen tissue structure and a first orientation of respective collagen fibers therein; a UVA light source adapted to a crosslinking within the collagen tissue structure; an optical system for deflecting and focusing the UVA light on a focus point behind an aperture within the imaging volume; and a processing and control unit adapted to receive data relating to a refractive error of the eye, to determine a second collagen tissue structure with new corrective collagen crosslinks, such as to achieve a minimized refractive error of the eye and a UVA light energy to induce the new corrective collagen crosslinks.
SYSTEMS AND METHODS FOR OCULAR LASER SURGERY AND THERAPEUTIC TREATMENTS
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.
EFFECTIVE OCULAR LENS POSITIONING METHODS AND APPARATUS
The methods and apparatus disclosed herein can be used to adjust the effective lens position (ELP) of the eye in order to correct refractive error of the eye. The methods and apparatus can be configured to apply energy to the sclera and other regions of the eye in order to adjust the effective lens position of the eye for far vision. The sclera can be treated in order to shrink or relax the sclera, and combinations thereof in order to adjust the position of the lens of the eye in order to correct vision related to refractive error of the eye. A target location of the lens can be determined to correct the refractive error of the eye, and the energy applied in order to move the lens toward the target location.
APPARATUS FOR PATTERNED PLASMA-MEDIATED LASER OPHTHALMIC SURGERY
A system for ophthalmic surgery on an eye includes: a pulsed laser which produces a treatment beam; an OCT imaging assembly capable of creating a continuous depth profile of the eye; an optical scanning system configured to position a focal zone of the treatment beam to a targeted location in three dimensions in one or more floaters in the posterior pole. The system also includes one or more controllers programmed to automatically scan tissues of the patient's eye with the imaging assembly; identify one or more boundaries of the one or more floaters based at least in part on the image data; iii. identify one or more treatment regions based upon the boundaries; and operate the optical scanning system with the pulsed laser to produce a treatment beam directed in a pattern based on the one or more treatment regions.
METHODS AND APPARATUSES FOR THE TREATMENT OF GLAUCOMA USING VISIBLE AND INFRARED ULTRASHORT LASER PULSES
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 effected 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.

Systems and methods for affecting the biomechanical properties of connective tissue
A device for delivering ablative medical treatments to improve biomechanics comprising a laser for generating a beam of laser radiation used in ablative medical treatments to improve 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 material, a lens operable to focus the beam of laser radiation onto a target material, and a power source operable to provide power to the laser and controller.
Image guidance apparatus for glaucoma surgery
An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.
