How it works

From patient data to clinical insight in seconds

Designed around chairside workflow. No training required.

01
Enter patient data
Age, current axial length (OD/OS), and a prior measurement. Or skip prior data for a first-visit baseline estimate.
~10 seconds
02
See risk & projection
Growth rate, percentile rank, composite risk score, and projected axial length at age 18 — with and without treatment.

Clinical use

Built for real-world myopia management

Designed to support chairside decision-making without replacing clinical judgment. Outputs are clearly labelled as educational decision support.

Aligns with current myopia management guidelines
Efficacy values sourced directly from primary RCTs — Chamberlain 2019, Bao 2022, LAMP study, ATOM2, and more.
Suitable for patient and family discussion
A parent-facing view translates clinical numbers into plain-language outcomes. Turn the screen to parents and they understand immediately.
Deterministic scoring in core calculations
The projection engine is pure math. Clinical Summary is a separate, optional documentation workflow.
Multi-visit longitudinal tracking
Track progression across unlimited visits per patient. Growth rate, interval warnings, and treatment response update automatically.
Clinical evidence base

All projection values and treatment efficacy figures use documented model inputs. View clinical model transparency.

Methodology

How the projections are calculated

Every number has a source. The projection engine uses peer-reviewed normative datasets and RCT-derived efficacy values.

View projection formula +
Core projection formula
AL_projected = AL_current
  + growth_rate × years_to_18
  × (1 − tx_efficacy)

Where growth_rate = observed ΔAL / interval
tx_efficacy = evidence-derived model input
Uncertainty bands are illustrative, not validated intervals

Composite risk score uses AL percentile (30%), growth velocity (28%), projected AL@18 (22%), parental myopia (12%), and near-work hours (8%). Weights derived from Tideman et al. 2018. The composite score is a clinical communication aid, not a validated diagnostic instrument.

Uncertainty bands are illustrative and have not been validated as prediction or confidence intervals. Individual outcomes vary.

Efficacy values represent change in axial elongation vs untreated control at ~2-year RCT endpoints — not final AL or cure rates. Treatment availability and regulatory approval vary by country; this site does not provide prescribing instructions. † Combination Therapy is a modeled composite (multiplicative formula, capped at 75% in-app); no single RCT validates this figure directly. Individual treatment defaults are conservative app coefficients for educational projections, not head-to-head clinical equivalence claims. See Methodology for the full model.

FAQ

Common questions

Questions? Email support@myopiatracker.com

Is this a regulated medical device?+

No. MyopiaTracker is a clinical decision support tool for visualization and patient education. It does not diagnose, prescribe, or replace clinical judgment. Not FDA-cleared as a medical device.

How accurate are the projections?+

Projections use published normative sources including Tideman 2018, McCullough 2020, Chen 2025, and app-documented treatment coefficients. Uncertainty bands are illustrative; individual outcomes vary. See the clinical model.

Do I need to create an account?+

Yes for the clinical workflow. Public pages are educational previews. A free clinician account saves 3 first visits and 3 parent reports; treatment comparison, Clinical Summary, QR sharing, and follow-up tracking require Pro.

Is patient data HIPAA compliant?+

Public preview data stays in the browser. Free accounts create a server-side login and limited cloud records for 3 first visits and 3 parent reports. A HIPAA Business Associate Agreement is available on Enterprise plans only.

What treatment modalities are included?+

Eight treatment options plus lifestyle reference: MiSight® 1 day, Stellest® (HALT), Ortho-K, MiyoSmart® (DIMS), Atropine 0.01%, 0.025%, 0.05%, Combination Therapy, and Outdoor/Behavioural context. Efficacy inputs are conservative defaults derived from published evidence.

Can I use this on a tablet during consultations?+

Yes. The app is fully responsive and works on iPad and Android tablets. Clinical workflow features require a clinician account and active Pro trial or subscription.
