COMBINATION TREATMENT USING ELT
20200330266 · 2020-10-22 ·

A method of treating a subject having glaucoma comprises performing excimer laser trabeculostomy (ELT) on a subject having glaucoma and having previously undergone a failed treatment or a treatment that has been rendered ineffective by progression of the disease. In some examples, the failed treatment is a non-surgical treatment comprising administering medicated eye drops. In some examples, the failed treatment is a laser treatment or surgical treatment, such as a trabeculoplasty, iridotomy, iridectomy, trabeculectomy, trabeculotomy, goniotomy, surgical insertion of a shunt or implant, deep sclerectomy, viscocanalostomy, or a combination thereof.

The invention provides personalized laser probes for use in laser systems, wherein each laser probe includes one or more characteristics tailored to a given user to thereby improve performance of and outcome of a laser treatment procedure.

CALIBRATION SYSTEM FOR IMPROVING MANUFACTURE TOLERANCE IN EXCIMER LASER OPTICAL FIBERS
20200330279 · 2020-10-22 ·

The invention provides an excimer laser system including a means for calibrating laser output to compensate for increased variation in laser optical fibers.

METHODS OF TRANSVERSE PLACEMENT IN ELT
20200330274 · 2020-10-22 ·

Glaucoma patients suffer from increased intraocular pressure due to blocked fluid flow from the anterior chamber of the eye. Methods of the invention include inserting a probe into an eye of a subject having glaucoma, adjusting placement of the probe to a position transverse to Schlemm's canal in the eye, and applying a plurality of shots from an excimer laser source while the probe is in the transverse position, thereby treating glaucoma by creating a plurality of perforations in Schlemm's canal and/or the trabecular meshwork. By providing a laser probe at a position transverse to Schlemm's canal, energy from the laser is delivered to a greater amount of surface area than if the laser was arranged in a parallel or perpendicular position to Schlemm's canal, resulting in optimal formation of perforations. The perforations allow for drainage of fluid and increased outflow of aqueous humor in the eye.

COMBINATION TREATMENT USING PHACO AND ELT
20200330275 · 2020-10-22 ·

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.

METHODS AND SYSTEMS FOR OCT GUIDED GLAUCOMA SURGERY
20200323687 · 2020-10-15 ·

Disclosed herein are systems and methods for aiding a surgeon to perform a surgical procedure on an eye. The surgical procedure includes inserting an elongate probe from an opening into the eye across an anterior chamber to a target tissue region comprising a trabecular meshwork and a Schlemm's canal. Exemplary systems include an optical microscope for the surgeon to view the eye with a microscope image during the procedure; an optical coherence tomography (OCT) apparatus configured to perform an OCT scan of a target location in the target tissue region during the procedure; and an image processing apparatus configured to generate an augmented image by overlaying an OCT image of target location and a graphical visual element identifying the locations, wherein the graphical visual element is registered with the microscope image to aid the surgeon in advancing a distal end of the elongate probe to the target location.

Laser surgery apparatus for contact laser surgery

The present invention relates to a laser surgery apparatus for contact laser surgery and to a method of using the laser surgery apparatus. The laser surgery apparatus (1) comprises a contact laser scalpel (3) for contact laser surgery, the contact laser scalpel (4) comprising an optical fiber (4) of IR laser radiation transmissive material and terminating at an optical fiber tip (5) having an exposed core region, and support means for holding said fiber and for positioning said scalpel (3). Said fiber tip (5) is tapered and disposed at a distal end of the scalpel (3) for contacting a tissue to be cut and comprises an uncoated contact surface (6) for transmit ting laser radiation and a guiding surface that is at least partially reflective to laser radiation and provided such that laser radiation guided by said optical fiber (4) to said fiber tip (5) will be at least partially reflected by said guiding surface and emitted through said uncoated contact surface. The contact laser surgery apparatus further comprises a pulsed laser source (2) adapted to provide pulse durations in the femtosecond, picosecond and/or nanosecond range, and light transmitting means (9) connecting said laser source (2) to said optical fiber (4) of said scalpel (3) for conveying laser radiation from said laser source (2) to said optical fiber (4) such that the conveyed laser light is emitted at said uncoated contact surface of the fiber tip.

ANGLE-OPENING GLAUCOMA TREATMENT METHODS AND APPARATUS

An iridocorneal angle of the eye can be opened with a plurality of treatment locations at least about 2 mm radially outward from a limbus of the eye. The opening on the angle can be beneficial for treating both narrow angle glaucoma and open angle glaucoma. The plurality of treatment locations located away from the limbus can decrease invasiveness and complexity of the procedure. The plurality of treatment locations at least about 2 mm away from the limbus can provide tensioning to zonules coupled to the lens of the eye to flatten the lens of the eye, which can allow the iris to move posteriorly so as to open the iridocorneal angle. The plurality of treatment locations may comprise scleral locations, in which shrinkage of scleral tissue at the plurality of treatment locations provides tensioning to the zonules.

Method Of Treating, Reducing, Or Alleviating A Medical Condition In A Patient
20200289534 · 2020-09-17 ·

A method of treating, reducing, or alleviating a medical condition in a patient is disclosed herein. The method includes administering to a patient in need thereof a biocompatible drug comprising one or more antiviral medications together with one or more cell pathway inhibitors dissolved in a non-toxic semifluorinated alkane, the patient having one or more respiratory tract inflammatory diseases, the one or more cell pathway inhibitors blocking an inflammatory response of inflamed tissue without inhibiting an immune response of the patient, and the semifluorinated alkane evaporating quickly upon administration to the patient so as to leave the biocompatible drug at a desired treatment location. The administration of the biocompatible drug to the patient treats the one or more respiratory tract inflammatory diseases, reduces the symptoms associated with the one or more respiratory tract inflammatory diseases, and/or alleviates one or more respiratory tract inflammatory diseases.
