3nethra bio M
The 3nethra bio M is an advanced, fully automated myopia management platform powered by OLCR (Optical Low Coherence Reflectometry) technology. It captures 13 key parameters across both eyes in just 15 seconds. It tracks axial length and axial ratio against age-based percentile curves to help clinicians detect myopia progression early, identify its type and severity, and plan personalized interventions with confidence.
- Myopia type & severity detection
- Axial length & axial ratio trend charts
- Refractive error & growth risk analysis
- 13 parameters, both eyes, 15 seconds
3nethra bio
3nethra bio is an optical bio meter designed to provide precise measurements of key eye parameters using low-coherence interferometry.
It aligns accurately to the eye axis and measures axial length, corneal curvature (K1 & K2), axis, central corneal thickness, white-to-white distance and pupil diameter. It also analyzes myopia growth risk. Its fully automated design simplifies data capture and supports diagnosis, treatment planning and overall clinical efficiency.

Clinical Highlights
-
High-Precision Axial Measurements with OLCR Technology
Uses Optical Low Coherence Reflectometry to measure axial length with high precision across a 12–38 mm range.
-
Axial Length Trend Chart
Plots each eye’s axial length against age-based percentile curves (P5–P95) to show whether growth is normal or progressing abnormally.
-
Myopia Type & Severity Detection
Distinguishes axial, curvature and comprehensive myopia, so clinicians can make more personalized treatment choices.
-
Axial Ratio Trend Chart
Tracks the AL/CR ratio, a single sensitive indicator of myopia risk, to detect progression earlier and refine management strategies.
-
10-Inch Touchscreen Display
Enables intuitive and efficient operation through a user-friendly interface.
-
Refractive Error & Growth Risk Analysis
Uses longitudinal axial length data to assess eye growth velocity and classify patients into Low, Moderate or High risk.
