title: Critical corneal oxygen values: a summary.
abstract: Data from several previous studies were collected and analyzed by remeasuring test hydrogel contact lens oxygen transmissibilities (Dk/L) at ocular temperature to arrive at summary critical human pre-corneal oxygen tension (30 mmHg), and required Dk/L (18 X 10(-9) cm ml O2/sec ml mmHg) under open-eye conditions. Estimations for closed-eye (extended wear) conditions were also performed.
