An ophthalmic laser ablation system is described with various optional features, some especially suitable for non-penetrating filtration on an eye. In one example, focusing of an ablation laser uses a movable lens coupled to a pair of converging light sources, which converge at the focal distance of the lens. In another example, laser ablation settings are selected for optimal ablation and minimal amount of thermal damage of a layer of percolating scleral tissue.

The present invention refers to a Laser therapy system and a method for treatment of a sclera/conjunctiva of an eye, comprising: a dispenser for a photosensitizer agent; a 3D imaging unit; an image processing unit being adapted to recognize the collagen tissue structure and to determine a thickness thereof; a UVA light source being adapted to a crosslinking of the collagen tissue; a second Laser light source being adapted to be absorbed mainly by varicose blood vessels; an optical system for deflecting and focusing the UVA light and the second Laser light on a focus point within the sclera/conjunctiva; a processing and control unit being adapted to determine a target thickness and a thickness deviation; a pattern for an application of the UVA light energy; a UVA light energy to effect a growth of the collagen tissue structure until the target thickness is achieved.

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.

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.

A glaucoma drainage implant comprising a pressure relief valve via which aqueous humor can be drained. The pressure relief valve has a pressure relief flap which is movably connected with a base plate of the implant, which is to be embedded in a sclera, wherein the pressure relief flap has an actuation area by means of which the pressure relief flap can be mobilized non-invasively during a post-operative healing phase or thereafter. The actuation area is preferably designed as a thermomechanically active area.

A laser instrument for therapy on the human eye, designed for surgery of the cornea, the sclera, the vitreous body or the crystalline lens, especially suitable for use in immediate succession with other instruments for eye diagnosis or eye therapy, in such a way that during the alternating use of the various instruments, the eye or at least the patient preferably remains in a predetermined position and alignment within one and the same treatment area.

Disclosed is a patient interface for affixment on onto a patient eye, said patient interface including a negative pressure cavity with a top wall and a circumferential outer wall, an optical passage, wherein the top wall circumferentially surrounds the optical passage and wherein the circumferential outer wall projects from the top wall and circumferentially surrounds the optical passage; a number of rib members, the rib members projecting separately from each other from the top wall into the negative pressure cavity between the circumferential outer wall and the optical passage.

A surgical instrument and a method of repairing a retinal detachment in an eye are provided. The surgical instrument includes a free end and an operable end opposite to the free end for insertion around the eye through an entry aperture. The tip of the operable end includes a hook portion that is rotated around a circumference of the eye upon insertion. Accordingly, the instrument allows for decreased procedure time and also decreased inflammation and trauma to 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.
