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.
Image guidance methods and 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 500 can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe 500 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 500 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.

AN ACOUSTIC DIVERTER FOR IMPROVED SAFETY DURING OPHTHAMLMIC LASER TREATMENTS
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.
System and methods using real-time predictive virtual 3D eye finite element modeling for simulation of ocular structure biomechanics
Disclosed are systems, devices and methods for performing simulations using a multi-component Finite Element Model (FEM) of ocular structures involved in ocular accommodation.
Device and method for treatment of retinal detachment and other maladies of the eye
The present invention includes a device for effecting deformation of a sclera of an eye, including an expandable, mesh tube having holes dispersed through an entire surface thereof and with first and second tapered ends, and inserted unexpanded to deform the sclera when expanded. A central portion is intrascleral, with the first and second tapered ends external to the sclera on top of an intact scleral surface to deform during expansion, and simultaneously causes the sclera to be deformed so that the sclera moves towards the inside of the eye while simultaneously causing the sclera to move towards the outside of the eye. The mesh tube includes struts, connecting points of the struts are of different sizes, the first and second tapered ends and the connecting points within the tapered ends are thicker than the connecting points of the mesh tube, and the mesh tube includes fixation tabs.

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 affected 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.

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.
