Glaucoma is the leading cause of preventable blindness, estimated to cause bilateral blindness in 11 million people by 2020. Treatment modalities include surgery to reduce intraocular pressure (IOP). State-of-the-art glaucoma filtration surgery (GFS) has been used for decades with only slight improvements and has high failure and complication rates. This postdoc project is part of a bigger program in which we will combine expertise on ophthalmology, cell biology, biomedical and mechanical engineering as well as polymer chemistry to develop a novel procedure for GFS. This consists of a new, minimally invasive and smart implant.
In this postdoc project, we will develop a smart solution to control the flow rate through the novel glaucoma implant, post-operatively. The most recent implant consists of a flexible polymer tube (inserted in the eye with a surgical procedure) that connects the anterior chamber (under the cornea) to the sub-conjunctival space, acting as a shunt. Due to the pressure difference between these locations, aqueous humor flows from the anterior chamber to the sub-conjunctival space thereby lowering the pressure in the eye. Once implanted, the flow rate through this microshunt cannot be controlled anymore, although clinical practice has shown that this is highly desirable for many patients to control intraocular pressure (IOP) and reach target IOP. We will combine our expertise on smart responsive materials, microfluidics design, and microfabrication, to develop a polymeric shunt that allows for post-operative, non-invasive adjustment of the hydrodynamic resistance and therefore for control of flow. This work involves materials research, microfluidic shunt design, microfabrication, and experimental testing. The final aim is to produce prototype shunts that can be used for animal testing by our project partners.
The postdoctoral researcher will be embedded in the Microsystems group headed by prof.dr.ir. Jaap den Toonder, in close collaboration with the Stimuli-responsive Functional Materials & Devices (SFD) group headed by prof.dr. Albert Schenning and the BioInterface Science group headed by Jan de Boer. All three research groups are part of the Institute of Complex Molecular Systems (ICMS). The Microsystems group manages the Microfab lab, a state-of-the-art micro fabrication facility that houses a range of micro manufacturing technologies – microfluidics technology is one of the main research pillars of the group. The project is a collaboration within a larger consortium, including Maastricht University Medical center, and Santen - Innfocus.
We are looking for a scientist with a background in materials science, mechanical engineering, biomedical engineering, or chemical engineering, who enjoys to work in a multidisciplinary academic environment and translate his/her knowledge towards applications. The ideal candidate would have experience in both microfluidics and smart materials, but excellent candidates with a background in one area (and an interest to master the other) will also be considered. Important personal skills include a proven ability to manage projects, collaborate with external parties and be self-driven.
