ERG-Jet Electrode (12/pack)

These ERG-Jet electrodes come in form of a contact lens which allows for ERG (Electroretinogram) recordings. ERG-Jet electrodes are made of a disposable gold-ring (sterilized, single-use only) corneal lens. The contact lens itself which holds the gold ring electrode is concave-shaped and has a diameter of 12mm. The ERG-Jet contact lens electrode comes pre-assembled with a 100cm connection cable that terminates in a DIN 1.5mm touch-proof (TP) connector.

The ERG-Jet is used to support diagnostic systems for anomalies of the eye by transmitting the retinal electrical signal. ERG-Jet electrodes can also be used for veterinary applications thanks to their simplicity and small size.

12 ERG-Jet electrodes per pack.

Application Note

1. Anesthetize the cornea. Hold the concave surface of the ERG-Jet lens upwards and fill it to slightly below the rim with a 2-3% sterile methylcellulose solution.
2. Set ERG-Jet lens onto the cornea by the same procedure used for a conventional contact lens. First, lift the patient’s upper lid and have him/her look slightly downwards. Gently rest the lens' front edge (with the concave surface upwards) on the lower lid, then tilt the lens backwards onto the cornea.
3. Attach the connection wire to the patient’s face.
4. To remove the lens, pull the upper eyelid upwards, then pull the lead wire gently upwards to lift the lower edge of the lens out of the eye.
