Abstract
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.
Claims20
A shunt for draining fluid from an anterior chamber of an eye, the shunt comprising:
- a main section having an inlet, an outlet, and wall defining a lumen with a first cross-sectional area and being configured to direct the fluid from the anterior chamber through the inlet toward the outlet such that, when positioned in the eye, fluid is released through the outlet at a location having lower pressure than the anterior chamber;
- and
- a detachable flow restriction section in fluid communication with the main section, the detachable flow restriction section having a second cross-sectional area that is less that the first cross-sectional area.
An eye implant that conducts fluid at a first nonzero flow rate, modifiable to a second flow rate, when the implant is in an eye, by removing a removable part of the implant residing in the anterior chamber.
