RHR. M. HillJSJ. E. SchultzGTG. R. Thayer

Key Points

  • The research aims to evaluate how well an experimental hard contact lens material allows oxygen to reach the corneal surface.
  • Measured oxygen transmission for different center thicknesses of hard contact lens material.
  • Conducted experiments under static, in vivo conditions.
  • Compared oxygen transmission with epithelial oxygen requirements.
  • Oxygen availability varied significantly with different lens thicknesses.
  • Some thicknesses met epithelial oxygen requirements, while others did not.

Abstract

ABSTRACT The availability of oxygen to the corneal surface through an experimental “hard” contact lens material was measured for several center thicknesses under static, in vivo , conditions and the performances compared with epithelial requirements.
