The ERG-Jet is a corneal contact lens incorporating an electrode that captures the electro-retinogram, ERG, generated by the light stimulation of the Human or animal* retina.

The ERG-Jet is a contact lens electrode intended to be applied on the cornea and to be used for the measurement and recording of electroretinography (ERG) signals, to support the diagnosis of retinal dysfunctions. It can be used to perform either full-field or multifocal ERG assessment.

The ERG-Jet is a plastic lens with a concave shape. A thin gold ring on the inside of the lens allows the detection of the electrical signal. A conductive wire transmits the electrical signal to a preamplifier and a data processing device.

The ERG-Jet is also appreciated in the veterinary* field thanks to its simplicity and its smaller size compared to some competing products.

*animal use is out of the scope of the medical device according to MDR 2017/745
