3nethra aberro, Handheld Auto Refractometer
PRODUCT DESCRIPTION
3nethra Aberro – Handheld Autorefractometer
The 3nethra Aberro is an advanced handheld autorefractometer that utilizes Shack-Hartmann Wavefront Sensor Aberrometry to deliver fast, accurate, and comprehensive refractive error assessments. Designed for mobility and precision, it is ideal for diverse clinical and outreach environments, including pediatric, geriatric, and bedridden patient care.
What It Does
The device measures key components of refractive error:
- Sphere (SPH): Detects myopia (nearsightedness) or hyperopia (farsightedness)
- Cylinder (CYL): Measures astigmatism
- Axis: Determines the orientation of astigmatism
Results are obtained within seconds, providing quick and non-invasive assessment by analyzing how light reflects off the retina.
Key Features
Feature Description Shack-Hartmann Wavefront Sensor Advanced aberrometry for high-accuracy, full-spectrum refractive analysis Portability Lightweight and handheld—perfect for fieldwork, mobile clinics, and screenings Rapid Measurements Delivers results in just a few seconds Touchscreen Interface Intuitive, user-friendly controls for seamless operation Connectivity Supports Bluetooth, Wi-Fi, or USB for data transfer and EMR integration Pupil Size Measurement Integrated pupillometry for comprehensive eye data Single & Bifocal Prescription Support Versatile prescription support across patient types Supine Position Testing Enables comfortable testing of bedridden or immobile patients.
Technology Highlight: Shack-Hartmann Wavefront Aberrometry
Unlike traditional autorefractors, the 3nethra Aberro detects both:
- Lower-order aberrations
- Myopia
- Hyperopia
- Astigmatism
- Higher-order aberrations:
- Impact visual quality in low-light conditions
- Crucial post-refractive surgery or in cases like keratoconus
- Often missed by conventional autorefractors
This technology offers superior diagnostic precision and enables more tailored prescriptions and treatment plans.
Clinical Applications
- ✅ Myopia (Nearsightedness)
- ✅ Hyperopia (Farsightedness)
- ✅ Astigmatism
- ✅ Anisometropia (unequal refractive power between eyes)
- ✅ Anisocoria (unequal pupil sizes)
- ✅ Keratoconus
- ✅ Cataracts
- ✅ Higher-order aberrations
- ✅ Supine testing in bedridden or hospitalized patients
Use Case Scenarios
- Mobile eye care and outreach camps
