A positioning sensor for tonometric applications [PDF]

, 1992
In this paper we present a sensor, which is designed for application in a tonometer, an instrument for the measurement of intraocular pressure. The sensor measures diameter and position of a part of the eye globe that is flattened by the tonometer.

Corneal Biomechanics in Ectatic Diseases: Refractive Surgery Implications. [PDF]

, 2017
BACKGROUND: Ectasia development occurs due to a chronic corneal biomechanical decompensation or weakness, resulting in stromal thinning and corneal protrusion. This leads to corneal steepening, increase in astigmatism, and irregularity.
