Electroretinography is a common technique for diagnosing and following up on eye conditions.
Commercial electroretinography devices are rigid and require electrodes, often in the form of a hard contact lens.
Often requires general anesthesia or sedation, in addition to topical anesthesia.
Researchers unveiled a soft contact lens that is easy on the eye, provides superior electroretinography signal recordings.
“Beneficial to painless diagnosis or early detection of many ocular diseases,” -Chi Hwan Lee, the lead scientist.
Flexible electronics and a new way to print the sensor components, using wet adhesive bonding onto a soft contact lens.
Other types of sensors should be able to be attached to contact lenses to provide additional capabilities.
“Spontaneous retinal activity with improved accuracy, reliability and user comfort,” - Pete Kollbaum, co-researcher.
