Ophthalmology Toolbox

Four new clinical calculators: Age to Bifocal Add, Rx Toolkit, Prism Toolkit and AC/A Ratio. Dial in values and results update instantly, with sources one tap away. -- NEW CALCULATORS -- • Age to Bifocal Add — Set your patient's age for a tentative near add at 40 cm, with the full age-band table alongside. • Rx Toolkit — Transpose between plus and minus cylinder, find the spherical equivalent, and vertex-compensate between spectacle and contact lens powers, rounded to steps you can order. • Prism Toolkit — Prentice's rule for both lenses at once: vertical imbalance at the reading level, prism from a PD error checked against ANSI Z80.1, and the decentration needed to create a given prism. • AC/A Ratio — Calculated and gradient methods side by side, the binocular vision pattern they point to, and how a near add will shift the near phoria. -- UI IMPROVEMENTS -- • Retina Viewer zoom is now a smooth ruler: flick to glide, feel a tick at every step, and watch the preview zoom fluidly. • Precision rulers with haptic ticks make values quick to dial in. • Refreshed home screen with the new Calculators section, and the app name moves into the navigation bar as you scroll. • Help and References sheets share a cleaner, consistent design across every tool.
