Comparison of intra-ocular poressure with and without soft contact lenses using the non-contact tonometer and the tonopen

1 May 2001

Abstract

The NCT and Tonopen have become popular tools for measuring IOP. It is not known whether accurate measurements can be taken while soft contact lenses are worn. IOP was measured with both instruments on patients with and without contact lenses. Both plus and minus 3.00 lenses were used on all subjects. Results indicate that soft contact lens wear will not affect measurement taken with the Tonopen. Minus soft contact lenses will not aIter IOP taken by the NCT. Plus lenses, However, appear lo cause higher NCT readings than those taken without my lenses.
