Influence of lens material and intra-ocular pressure on the outcome of non-contact tonometry over soft contact lenses

ΔIOP appears to be related to lens power, material and to a lesser extent IOP. Practitioners should derive their own empirical relationship between ΔIOP, lens power and IOP for the specific types of soft lenses they commonly use. This would improve efficiency in the screening of IOP in more susceptible soft lens wearers.
