Briefings

A KAIST-led team developed a wearable patch to deliver eyedrops in space, overcoming the lack of gravity that makes eye drops difficult to apply. The research was led by Professor Ki-Hun Jeong from KAIST and Professor Se Joon Woo from Seoul National University Bundang Hospital, with findings published in Sensors and Actuators B: Chemical.

Key points

• A KAIST research team led by Professor Ki-Hun Jeong developed a wearable patch to deliver eyedrops in space, solving the gravity-dependent application issue.
• The study was conducted in collaboration with Professor Se Joon Woo from Seoul National University Bundang Hospital.

Context

This research addresses a critical challenge in space medicine where standard eye drops cannot be applied due to the absence of gravity, potentially affecting astronaut eye health.

Limitations

The evidence is limited to the initial research paper published in Sensors and Actuators B: Chemical. No follow-up data, clinical trials, or long-term effects are provided in the source.
