Limit aesthesiometry.
An aesthesiometer with disposable monofilaments is designed for measuring very small pressures on the corneal surface. This was achieved by using various lengths of a nylon monofilament with diameters of 0.08, 0.10, and 0.12 mm. With these lengths and diameters pressures between 0.1 and 1.0 g/mm2 can be exerted on the corneal surface.
