20210259883 · 2021-08-26 ·

The present invention belongs to the field of instruments for examination and treatment of human eyes. The invention relates to an acoustic diverter, which is used during laser treatment of eyes based on photodisruption within the eye, such as capsulotomy, iridotomy and vitreolysis. The present invention achieves the task of limiting or preventing acoustic waves to be focused in the eye so that the threshold negative pressures for injuries is not reached by providing an acoustic diverter, which has a geometry of an anterior surface concave, flat or slightly convex such that it prevents or decreases refocusing of acoustic waves back into the eye, and wherein the acoustic diverter is made of any biocompatible and sterilisable material transparent for the visible and near IR light. The preferred material has acoustic impedance between 1.4 to 1.7×10.sup.6 kg/(m.sup.2.Math.s) and/or attenuation coefficient more than 1 cm.sup.−1 at 10 MHz in order to ensure improved dispersion or attenuation of acoustic waves.

LASER VITRECTOMY AND ILLUMINATION PROBE
20210290438 · 2021-09-23 ·

The present disclosure generally relates to microsurgical instruments for ophthalmic surgical procedures, and more particularly, microsurgical instruments having combined illumination and laser vitrectomy functions. In some embodiments, a surgical instrument includes a base and a probe having a main lumen and a port at a distal end thereof. In some embodiments, the probe may further include one or more optical fibers within the main lumen and configured to project laser light and illumination light. According to some embodiments, as soon as vitreous material is drawn into the probe, e.g., through the port, the vitreous material passes through a volume irradiated by the laser light emitted by the optical fibers, thus severing the vitreous material. Simultaneously, the illumination light provides enhanced visualization of the intraocular space during severance and removal of the vitreous material.

Ophthalmological laser therapy device

An ophthalmological laser therapy device including a laser system, an x-y scanner, collecting optics and a z-scanner.

A probe as disclosed herein is capable of treating both the Schlemm's canal (SC) and the trabecular meshwork (TM), or both the pars plicata and the iris root site of the eye, with electromagnetic radiation (e.g., laser light) to improve aqueous humor outflow and thus decrease intraocular pressure (IOP). The laser probe can include a tip capable of being placed on an eye, such as on a corneal limbus or a scleral limbal area of the eye. The tip can include an optical waveguide angled to direct laser light through both the SC and TM, or both the pars plicata and the iris root site of the eye. The laser light can be continuous or pulsed, and can be configured to provide appropriate therapy to both the SC and TM, or to both the pars plicata and the iris root site. The laser probe can facilitate performing trans-scleral trabeculoplasty treatment, especially trans-scleral Schlemm trabeculoplasty, and performing iridoplasty treatment.
