Estimating the term…
Methods and devices for adjusting or configuring the flow rate of an intraocular shunt are provided whereby hypotony can be avoided by increasing the flow rate through the device. In some embodiments, the device is a shunt that can have a first flow that can be modified to a second flow by modifying the shunt, such as by cutting the shunt. Additionally, one or more dissolvable portions can be present to provide an initial flow restriction and subsequent increase in flow over time.
A shunt for draining fluid from an anterior chamber of an eye, the shunt comprising:
An eye implant comprising a lumen, a first, permanent flow restrictor, a second flow restrictor, and a pharmaceutical or biological agent, the first and second flow restrictors being disposed within the lumen, the first flow restrictor positioned adjacent to an inlet of the implant, and the second flow restrictor positioned adjacent to an outlet of the implant, the implant being configured to conduct fluid at a first nonzero flow rate, modifiable to a second flow rate, when the implant is in an eye, by removing at least a portion of the first flow restrictor or the second flow restrictor, the implant configured to extend from the anterior chamber to a region of lower pressure and deliver the pharmaceutical or biological agent to the eye.
