The influence of environment on the performance of the Bausch and Lomb Low Heat Unit

Abstract

Timdtemperature profiles for the Bausch and Lomb Low Heat Contact Lens Disinfection Unit were established during operation under a number of extreme but possible environmental conditions. These included low voltages, partially filled contact lens cases, low environmental temperature, grit in the heat well, saline in the heat well and combinations of these. Only the extreme combination of low temperature and grit in the heat well lowered performance to an unacceptable level. We recommend that practitioners strongly advise patients to keep the units clean.
