LUNEAU

The retractable Aesthesiometer with a 12/100 mm nylon thread for measuring the tactile sensitivity of the Cornea and eyelid margin.

Provides direct reading on the instrument of the length of the very precisely calibrated filament, based upon the principle of pressure transmitted axially by a nylon monofilament, of known diameter but of variable length, for a given bending stress. Examination of corneal sensitivity in tumors, such as acoustic neuroma or angioma.
