Web14 Sep 2024 · The shell thickness used for contact is governed by the following: a) the shell thickness (applied via *SECTION or *ELEMENT) multiplied by any scale factors. b) 40% of the edge length. With edge length calculated as Min (N4-to-N1, N1-to-N2, N2-to-N3). This means that when using small elements it is possible to have contact occur later than ... WebManufacturers of devices that measure corneal thickness (such as the corneal pachymeter) often supply clinicians with tables, which help to convert corneal thickness measurements into an "adjustment factor." This adjustment factor is applied to the measured IOP, in order to determine more closely the "true" IOP for a given eye. Webt = bar thickness.
