    摘要: A technique and device for relieving intraocular pressure within the eye with a reduced risk of inflammation that may be caused by the retrograde flow of fluid and inflammatory debris back into the eye after a glaucoma surgical procedure has been performed. A unidirectional drainage device is implanted to drain fluids away from the eye. The device allows fluid flow away from the eye with a minimal pressure gradient (5 mm Hg. or less), and includes means to prevent retrograde flow. At the time of implantation, the drainage passageway is initially restricted or closed by a flow restrictor at a point downstream from the minimal pressure gradient unidirectional valve. Between the unidirectional valve and flow restrictor is a drainage trap in which debris is receivable without restricting the operativeness of the unidirectional valve. After sufficient scarring and fibrosis has occurred to prevent excessive drainage that might cause hypotony, the flow restrictor is removed to allow the free flow of fluid away from the eye, with inflammatory debris being prevented from reentering the eye. In a second embodiment, the flow restrictor is located at the distal end of the receptor tube of the device within the eye, and acts to prevent the influx of fluids into the device from the eye during the initial period after implantation. Upon removal of the flow restrictor, the free flow of fluids away from the eye is allowed while retrograde flow back into the eye is prevented by the unidirectional valve.

    摘要: A posterior chamber intraocular lens implant having improved fixation where there is no posterior capsule remaining to serve as a fixation platform. In addition to ciliary sulcus haptics, the lens implant has two oppositely disposed loops which serve as suture sites for the suturing of the implant directly to the iris. The loops, which are only so large so as to accommodate a 9-0 size suture thread, extend anteriorly from the optical lens to act as a cushion between the lens and the iris of the eye, and radially such that they align with the striae of the iris when the implant has been positioned within the eye, whereby inflamation of the iris is minimized.

    摘要: A corneal press is disclosed for accurately trephining corneal tissue. The disclosed press includes a base support member, a modular cutting block, two guide posts, a collet mount, a threaded drive mechanism, and a set of modular collets. The base includes means for securely holding the cutting block in position for holding a corneal specimen to be cut about a defined axis. The guide posts are attached to the base in offset parallel alignment relative to the defined axis. The collet mount is mounted onto the guide posts and is slidable relative thereto toward and away from a corneal specimen positioned on the cutting block mounted onto the base. The threaded drive mechanically links the collet mount to the base such that the operation of the threaded drive causes the collet mount to move along said guide posts toward or away from a specimen positioned on the base. Each of a set of modular collets are mountable to the collet mount and are configured to securely hold a trephine of a specifically defined diameter in centered alignment about the defined axis. When so positioned for a cutting operation, the operation of the threaded drive causes the trephine to move along the defined axis and to precisely cut a specimen of corneal tissue positioned on the base about said axis. An alignment sight hole, which extends through collet mount in alignment with said defined axis and which is co-aligned with a sight hole extending a collet mounted therein, allows for the visual alignment of the cut to be made and also provides a means for directing illumination onto the cutting area during a cutting procedure.
