Eye care: Taking electroretinography to the next level with a soft multi-electrode system

Electroretinography (ERG), which involves measuring electric potential in the retina, is a powerful tool for diagnosing and studying ocular diseases. However, multi-electrode systems for ERG are usually built on top of hard, uncomfortable contact lenses. To address this issue, researchers have developed an innovative multi-electrode ERG system built on top of commercial soft contact lenses. Demonstrating excellent performance and biocompatibility, the proposed system will help push the envelope of what is possible with ERG.
