  • Publication number: 20240024573
    Abstract: Apparatus and methods for introducing a solid or semi-solid intraocular drug-containing implant into the anterior chamber of an eye are described. The drug-containing implant can be a rod-shaped biodegradable implant that may provide for the extended release of the drug and may be effective for treating a medical condition of the eye. The apparatus is ergonomically designed in the shape or style of a pen with tactile surfaces for easy gripping, a needle-rotation knob to permit orientation of the needle bevel in relation to the eye, and a spring-actuated mechanism for consistent deployment of the implant.

  • Publication number: 20230172948
    Abstract: The invention provides biodegradable implants sized for implantation in an ocular region and methods for treating medical conditions of the eye. The implants are formed from a mixture of hydrophilic end and hydrophobic end PLGA, and deliver active agents into an ocular region without a high burst release.

  • Patent number: 11210341
    Abstract: Systems and methods are disclosed for optimizing responses to queries. Analyses of user interactions and other behaviors can lead to association of queries with signals, including ASINs and other product descriptions. The associations can be algorithmically graphed and analyzed on a disaggregated basis and individually weighted to improve search recall and reduce the risk of returning defective search results. Machine learning techniques can further optimize the associations and/or the search results.

  • Publication number: 20150140062
    Abstract: Intraocular implants may include a corticosteroid and a biodegradable polymer associated with the corticosteroid to facilitate the release of the corticosteroid into an eye for a period of time. In some embodiments, ocular conditions, such as diabetic macular edema can be treated through administration of an intraocular implant including a corticosteroid and a biodegradable polymer associated with the corticosteroid to the eye of a human at a frequency of about once every six months to about once a year.

  • Publication number: 20140031833
    Abstract: An intraocular injector includes a syringe body having open-ended cone disposed in one end thereof along with a piston disposed in the body. A transparent implant holder having a lumen therein is aligned with an open-ended cone, a needle include a proximal end and a distal end with a bevel disposed on the distal end of the needle. A plunger affixed to the piston and slidable within a holder lumen and needle lumen is provided for injecting solid intraocular implants into an eye. A cylindrical syringe body shape facilitates control over the needle bevel orientation during injection of the implant into the eye.
