Visionix VX110 – Automatic Multi-Functional Eye Analysis Device
Visionix VX110 is a multi-modal eye diagnostic system that integrates advanced technologies such as automatic refraction measurement, Placido corneal topography, wavefront aberration measurement, retroillumination, and visual acuity analysis in both daylight and nighttime conditions. The device is designed to meet the comprehensive screening and assessment needs of the anterior segment for ophthalmology clinics, refraction facilities, and specialized contact lens fitting centers.
1. Summary of Features
📌 Automatic Refraction Measurement
- Quick and accurate measurement in just 0.2 seconds with a resolution of 0.01 D.
- Measurement range: sphere –20D to +20D, cylinder 0 to +8D, axis from 0° to 180°.
- Automatic XYZ alignment minimizes operational errors.
- Provides objective results in both bright (Photopic) and low light (Mesopic) conditions, facilitating effective day/night refraction comparison and establishment.
🔬 Wavefront Aberrometry
- Utilizes advanced Shack-Hartmann technology.
- Accurately measures both low-order and high-order aberrations.
- Approximately 1,300–1,400 points recorded on a Ø7 mm pupil.
- Displays aberration maps in Zernike coefficients, separating corneal – lens – overall aberrations.
- Integrates visual simulation with PSF (Point Spread Function) and MTF (Modulation Transfer Function) to visualize the impact of aberrations on vision.
🌀 Corneal Topography
- Placido technology: 24 light reflection rings for superior analysis.
- 6,144 measurement points, over 100,000 reflection pixels processed.
- Measurement range of power from 37.5 D to 56 D, coverage diameter from 0.75 mm to over 10 mm.
- 3D simulation of corneal curvature and color-coded topography maps.
- Full keratometry readings (SIM-K, eccentricity, curvature radius, meridian...) at Ø3, Ø5, and Ø7 mm regions.
- Analyzes corneal wavefront maps and simulates fluorescein contact lenses for Ortho-K or RGP designs.
🌙 Day & Night Vision
- Allows assessment of vision changes according to pupil dilation in different lighting conditions.
- Supports regional refraction analysis for pupil sizes: 2 mm – 5 mm – 7 mm.
- Automatically simulates objective vision according to dilated pupils in low light, aiding in night lens design or IOL fitting.
🧠 In-Depth Diagnosis
Keratoconus:
- Identifies and monitors through the KPI (Keratoconus Prediction Index).
- Automatically alerts for corneal abnormalities.
- Automates cone topography analysis, aiding in early disease detection.
Cataract Assessment
- For cataract assessment, the VX110 allows imaging of lens opacification and wavefront aberration analysis, helping doctors differentiate between corneal aberrations and lens/intraocular aberrations. Additional features include measuring internal astigmatism, evaluating kappa angle for intraocular lens (IOL) centration, assessing Z.4.0 values for selecting aspheric implants, and classifying cataract opacity using LOCS II and III scoring systems. Utilizing Scheimpflug imaging, retroillumination, Shack-Hartmann rings, and Placido rings, the VX120+ provides comprehensive insights into the severity of cataracts and supports treatment planning.
- Analyzes cataract opacity through retroillumination.
- Classifies cataracts according to the standard LOCS II and LOCS III scales.
- Separately evaluates intraocular (lens) aberrations and corneal aberrations.
2. Contact Lens Fitting Support
- Simulates fitting for RGP, Ortho-K, or multifocal contact lenses.
- Displays sagittal maps, lens sag, and lens descent maps.
- Combines corneal topography, refraction, and aberrations to optimize vision decisions with lenses.
3. Interface & Software
- 10.1” multi-touch TFT screen, resolution 1024×600 px.
- Simple, intuitive interface allows for quick operation via touch or mouse.
- Automatically stores patient data, easy result export, report printing, template configuration.
- Enables remote diagnosis, analysis, storage, and sharing of results via local area network (LAN).
- Supports direct printing through an integrated printer or export via USB.
