Optical pachometry measures anterior corneal oxygen flux under hydrophilic contact lenses, implying lens design affects oxygen supply.
Central corneal thickness of four human subjects was monitored by optical pachometry during wear of selected hydrophilic (polymacon) contact lenses of known parameters. Simple algebraic techniques were used to calculate anterior corneal surface oxygen flux using central corneal thickness change as an indication of tear layer oxygen tension.
