  • Publication number: 20210161713
    Abstract: A drainage device for use in an eye to drain aqueous humour so as to reduce intraocular pressure or for treating glaucoma. The device has a multi-lumen tube having a first end, a second end opposite the first end, and a plurality of lumen extending between the first end and the second end. At least one of the lumen is sealed at the first end. A flow through the multi-lumen tube is adjusted by forming at least one aperture open in one of the lumen through a wall of the tube and/or sealing at least one aperture open in one of the lumen. The tube has a longitudinal axis through the first end and the second end, and an outer surface extending between the first end and the second end. A cross-section perpendicular to the longitudinal axis has a non-circular shape at the outer surface with an aspect ratio of at least 3:1.

  • Patent number: 6976758
    Abstract: A gonioscopy lens employs a plurality of mirror sets so that substantially the entire periphery of the anterior chamber of an eye can be viewed without rotating or moving the contact lens. Each mirror set comprises a first mirror position anterior to the eye on one side of the optical axis and a second mirror positioned posterior to the first mirror on the opposite side of the optical axis. Each set is oriented relative to each other so that the second mirror receives light rays from the peripheral portion of the anterior chamber, reflects those rays to the second mirror to the first mirror, and then reflects the light rays in a generally anterior direction so that they can be used by an ophthalmologist employing the lens. The image viewed by the ophthalmologist is upright and located over its actual position.
