Clinical Tools
Clinical Tools & Calculators
Accurate, instant tools designed to support everyday optometric decisions — from lens calculations to ocular measurements.
Contact Lens Fitting Calculator
Determine optimal contact lens parameters including base curve, diameter, and power adjustments.
Use tool
Cornea Curvature
Convert keratometry readings (diopters to mm radius) and estimate corneal power.
Use tool
Axial Length Estimation
Estimate axial length from refraction and keratometry for IOL power prediction or myopia risk assessment.
Use tool
Vertex Distance
Correct spectacle power to contact lens power when vertex distance changes (e.g. 12 mm standard).
Use tool
Cross-Cylinder Calculator
Quickly resolve cross-cylinder refractions to final sphere, cylinder, and axis.
Use tool
Dry Eye Severity Grader
Grade DED severity from Grade 0 (Healthy) to Grade 4 (Very Severe) using TFOS DEWS II criteria — with instant management plan and referral triggers.
Use tool
Axial Length Growth Chart
Plot AL measurements against East Asian age-normalised percentile curves (P5–P95). Tracks progression rate and flags the IMI > 0.10 mm/year and ≥ 26 mm high-myopia thresholds.
Use tool
Glaucoma Risk Calculator
Stratify glaucoma suspect risk using CCT-adjusted IOP, vertical CDR, CDR asymmetry, age, family history, and myopia. Outputs risk tier and EGS/AAO-based management recommendation.
Use tool
Atropine Awareness Tool
Evidence-based co-management reference for atropine 0.01%, 0.05%, and 0.1% in myopia control — ATOM & LAMP trial efficacy, side-effect profiles, and follow-up schedules.
Use tool
Priority clusters
Tools that anchor the priority clusters
The fastest way to increase repeat visits is to tie calculators into high-frequency clinical clusters with obvious next-click references and pathways.
Dry eye
Link workup, severity grading, medication-awareness, and ocular surface differentials so clinicians can move faster from symptoms to plan.
Glaucoma
Keep risk stratification, co-management, and medication-awareness close together for repeat use in monitoring and referral decisions.
Cataract
Use cataract content mainly for recognition, documentation, peri-operative awareness, and referral-ready slit-lamp findings.
