PGI - Paul glaucoma implant. And one of my colleague went for it.
A new glaucoma implant developed by a National University Health System team reduces patients’ eye pressure (also known as intraocular pressure, IOP) for a longer period of time and enables less reliance on eye drops. The Paul Glaucoma Implant (PGI) is a glaucoma drainage device which regulates IOP and prevents further progression of the disease that leads to blindness. With a higher efficacy and safety profile in reducing IOP, this medical technology innovation advances the treatment of glaucoma. In patients with medically uncontrolled glaucoma, the PGI offers a viable option in the management of refractory glaucoma, a severe form of glaucoma that has a high risk of failure from conventional trabeculectomy surgery.
Led by Professor Paul Chew from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) and Senior Consultant at the Department of Ophthalmology, National University Hospital (NUH), the research team involved in the development and design of the implant comprises Adjunct Associate Professor Chelvin Sng, NUS Medicine, Visiting Consultant from the Department of Ophthalmology, NUH, and Medical Director, Chelvin Sng Eye Centre, as well as researchers at the National University of Singapore.
