Comparison of the calculated standing fields generated by the model. To facilitate the comparison of the calculated standing fields, parameters are extracted from the equatorial radius of the model and plotted against the normalized distance from the centre (r/a). (A) Plot of the extracellular Na+(■), Cl- () and K+ () concentrations (Molar units) versus relative distance from the lens core (r/a). (B) Plot of the intracellular Na+(□), Cl- () and K+ () concentrations (Molar units) versus relative distance from the lens core (r/a). (C) Plot of the intracellular (Δ), extracellular () and the trans-membrane (*) electrical potential fields (Volts units) versus relative distance from the lens core (r/a). (D) Plot of the intracellular () and extracellular (♦) hydrostatic pressure fields (kPa units) versus relative distance from the lens core (r/a). The electrochemical and pressure gradients are oriented to direct the extracellular solute and fluid fluxes towards the core of the lens, while fields in the intracellular space appear to favour an outward flow.
