The measurement of corneal sensitivity is key to diagnosing a wide range of diseases. There are numerous mechanical contact methods to stimulate the cornea and measure the degree of sensitivity, and the method chosen in each case will largely depend on the doctor.
We based our work on the research performed by Dr. Belmonte, among others, into stimuli created by controlled pulses of compressed air, and have designed a device that generates these controlled pulses using ambient air.
This esthesiometer is portable, and can be adapted to the standard equipment used by ophthalmologists. It can be positioned and operated without coming into contact with the patient, which means the test is much less stressful. The mechanism and the positioning system guarantee an unequivocal repeatable stimulus scale, irrespective of the methods used by the doctor.
