Power and Tear Volume Exchanges With Flexible Contact Lenses

Key Points

• The aim is to understand how power changes in flexible contact lenses relate to volumetric tear exchange.
• Utilized mathematical formulas to infer volumetric changes in tears.
• Analyzed power changes of flexible contact lenses in situ.
• Calculated changes along the lens radius to estimate tear volume.
• Demonstrated an approximate correlation between power changes and tear volume exchange.
• Identified factors that may influence the accuracy of calculations.
