The invention relates to an ocular implant for treating glaucoma. The problem addressed by the invention is to make it possible to drain aqueous humor from the anterior chamber of the eye into the subconjunctival or suprachoroidal space in order to lower the intraocular pressure in glaucoma cases. The device is to do away with the drawbacks of known valve mechanisms and should be economical to produce. In order to solve said problem, the glaucoma drainage implant is composed of an elongate, hollow main member in which a flow-limiting membrane is arranged in the inflow region.

A wide-angle optical unit for ophthalmological implants in the eye includes a lens system arranged in a rotationally symmetrical manner about an optical axis and further includes at least two lenses that rest one on top of the other in a planar manner and which are made of materials having different optical refractive indices. In addition, the wide-angle optical unit includes an optical decoupling structure and a trailing lens arranged proximally with respect to the interior of the eye. The trailing lens is mounted around the optical decoupling structure.

An implantable system for restoring accommodation capacity includes at least one ring configured to be implanted in a ciliary sulcus and a capacitor with a first capacitor plate and a second capacitor plate. The first capacitor plate is arranged on an implantable ring and the second capacitor plate is connected to a capsular bag.

An implantable system for determining the accommodation requirement in an artificial accommodation system by optical measurement of the pupil diameter and the surrounding luminance, including at least one optical system, at least one data acquisition system that does not contact the ciliary muscle and measures a diameter of the pupil and luminance around at least one eye as a physical control signal for the accommodation requirement, at least one data processing system for generating an actuating signal for the optical system from the detected physical control signals or for the purpose of switching to the standby mode, at least one energy supply system, and at least one fixing system. The system has one sensor or a plurality of sensors with sensor elements for measuring the pupil diameter and the surrounding luminance.

The present invention relates to an ocular implant, particularly a glaucoma stent. It is the object of the present invention to devise an ocular implant which allows the ocular eye pressure to be regulated, i.e., to be maintained at a desired level, while preventing the flow resistance from increasing over time, for example due to fibrosis. In order to achieve this object, the ocular implant according to the invention comprises a small tube (), the wall surface () of which encloses a hollow duct that is open on both sides in the longitudinal direction of the hollow duct, wherein a first opening () allowing ocular humor to flow in and a second opening () allowing the ocular humor to be discharged is provided, and wherein the wall surface () is formed by a liquid-tight material, and wherein at least one pressure-controlled valve () is disposed in the area of the wall surface ().
