IOLDx Clinical is a free, web-based cataract planning platform designed for cataract surgeons. It combines transparent IOL formula spread, premium IOL decision support, patient lifestyle scoring, toric planning, adjustable-IOL workflow, and FDA SSED-derived vision simulation — all in one browser workflow.
Existing IOL calculators are fragmented — one tool for formulas, another for toric planning, another for patient education, and little support for comparing the whole patient journey. IOLDx Clinical integrates calculation, counseling, workflow burden, and documentation in a single clinician-controlled workflow.
The vision simulation is derived from FDA Summary of Safety and Effectiveness Data (SSED) published defocus curves — the same clinical data used in the FDA approval process for each lens. This makes the simulation the most clinically grounded free patient education tool available.
FDA SSED-derived blur simulation — Visual blur is calculated from published logMAR defocus curve values at each scene's corresponding defocus distance. No other free web tool does this.
Complete surgical workflow — IOL power calculation (SRK/T, Hoffer Q, Holladay 1, Haigis), toric planning, premium lifestyle fit, adjustable-IOL suitability, workflow comparison, and patient vision experience in one integrated tool.
Vendor-neutral decision support — PrecisionIOL explains suitability, tradeoffs, expected visual profile, dysphotopsia risk, and journey burden without embedding proprietary formula engines.
Hardware-free patient simulation — Patients can experience their lens options on any phone or tablet browser before the consultation. No VR headset or clinic hardware required.
Free with no app download — Works instantly in any modern browser. Free account includes 3 saved sessions and full tool access.
IOLDx Clinical is built on Supabase (row-level security, HIPAA-eligible), Stripe (PCI-DSS payments), and AWS CloudFront (HTTPS-only delivery). Patient session data is de-identified — no PHI is stored. Full details on the Security page.
