Oxygen Tension under a Permeable Contact Lens with and without Tears

BWBarry A. Weissman

Key Points

  • The aim is to assess the impact of tear layers on oxygen tension under contact lenses.
  • Calculated oxygen tensions under daily wear and extended wear contact lenses
  • Compared conditions with and without consideration of tear layers
  • No tear exchange was involved in measurements
  • Tear layers do not significantly affect precorneal oxygen tension
  • Similar oxygen tensions were observed with both lens types

Abstract

Abstract Oxygen tensions were calculated under two different oxygen‐permeable, flexible contact lenses (daily wear and extended wear) both with and without consideration of tear layers (but without tear exchange). Tear layers do not have significant effects on precorneal oxygen tension.
