ULTRA for Presbyopia

3-Zone Progressive design, one plotted power curve with the near band beginning at the Y-axis, the intermediate band beginning just past the 1.0 mm tick and the distance band just past the 2.5 mm tick, plotted across 3.0 mm of radial displacement at -3.00D high add.

Optimized for 7 biometrics: pupil size, anterior chamber depth, higher-order aberrations, axial length, corneal topography and diameter, residual accommodation across 9 distances, and subjective refraction.

Two lens adds across the entire power range, selected from the spectacle add: Low for +0.75D to +1.50D and High for +1.75D to +2.50D.

Polyvinylpyrrolidone (PVP), grown around and throughout the silicone backbone in the second phase of the MoistureSeal polymerization, where it attracts moisture.
