Development of Novel Intraocular Devices (SAEEDAU19SF)


Project Description

Cataract is clouding of the lens of the eye, which can lead to vision impairment. The most common cause of cataract is ageing, but it can also develop at early ages in Children. Cataract is the leading cause of avoidable blindness and is considered as a major priority in the global initiative to eliminate avoidable blindness by the year 2020. Although cataract can surgically be treated to restore high-quality vision, posterior capsule opacification (PCO), most common complication of the surgery, can develop in a significant proportion of patients and may lead to secondary blindness.

Work carried out by our group, and others have highlighted some of the underlying mechanism and potential therapeutic benefit of clinically approved drugs developed as implantable devices (Healthcare Technologies, EPSRC).

This PhD research project will be aimed at the design and development of novel devices to restore vision and prevent PCO by targeting the pharmacological receptors in the posterior segment of the capsule of the eye. The student will gain experience into the smart drug delivery system and implant, from design and formulation to pre-clinical testing in human eye model. Conducting synthesis and fabrication of polymeric-based drug delivery system, design and optimisation of the drug release profile and investigating the performance of the novel drug delivery system in the human capsular bag model available in our lab.
