Cochet-Bonnet Aesthesiometer

• The Luneau Cochet-Bonnet Aeshesiometer is designed for rapid corneal sensitivity examinations.
• The Aeshesiometer is based upon the priciple of pressure transmitted axially by a nylon monofilament, of known diameter but of variable length, for a given bending stress.
• The length of the thread like mono-filament, controlled by the forefinger (shown above), ranges from 60mm to 5mm.
• As the length is decreased the pressure transmitted is increased from 11mm/grms to 200mm/grms.
• A scale on the Luneau Cochet Bonnet Aesthesiometer instrument indicates the length of the monofilament and is easily read during the operation.
• When not in use, the tip of the monofilament is fully retracted into the instrument body, protecting it against damage.
