Study on Micro-invasive Glaucoma Surgical (MIGS) Devices

Glaucoma is an ocular condition in which optic nerve damage occurs, frequently in the presence of increased pressure within the eye. Micro-invasive glaucoma surgery (MIGS) refers to a new group of surgical procedures which are characterized by the following features: high safety profile, minimal trauma, ease of use and rapid recovery. There are 3 main groups of MIGS devices, which drain fluid to different regions in the eye: the Schlemm's canal, the suprachoroidal space and the subconjunctival space. Though MIGS devices were introduced in the United States of America, Canada and Europe more than 5 years ago, and have attained the CE mark and FDA approval for some devices. Studies have shown that these devices have a high safety profile and are effective (1-5). However, MIGS devices are only recently available in Asia, and data on their clinical outcomes in Asian patients are limited.
