Human Corneal Oxygen Flux under Soft Contact Lenses

Key Points

• To evaluate how wearing hydrophilic contact lenses impacts oxygen flux to the cornea using central corneal thickness measurements.
• Monitored central corneal thickness of four subjects using optical pachometry.
• Applied selected hydrophilic (polymacon) contact lenses with known parameters.
• Calculated anterior corneal surface oxygen flux using thickness change as an oxygen tension indicator.
• Identified changes in central corneal thickness during lens wear.
• Demonstrated the relationship between lens type and oxygen supply to the cornea.
