Nonoptical Definition of Applanation Surface

Abstract

Based on the Imbert-Fick law and the theoretical considerations of Goldmann, new applanation tonometers were designed, still using an applanation diameter of 3.06 mm to avoid a new biometric calibration. Three different electronic recording devices were used for the area assessment. An optical, a capacitance and a digital line sensor were tested in first calibration experiments.

Assessing the sub‐basal nerve plexus of the living healthy human cornea by in vivo confocal microscopy

“…In addition, we found a statistically significant decrease in the nerve density of the sub-basal plexus with age, which may correlate with decreased corneal sensitivity with age. 20 Auran et al used in vivo confocal microscopy to observe the architecture and dynamics of the normal human anterior cornea. 6 They found anterior stromal nerves were radially orientated, and gently curved over long distances.…”
