Eyevis Scansys ECT1, Anterior Segment Analyzer 3D (Corneal Topographer)

A 3D anterior segment analyzer is a diagnostic imaging device used in ophthalmology and optometry to capture, analyze, and visualize the anterior segment of the eye in three dimensions. The anterior segment includes structures like:

• Cornea
• Anterior chamber
• Iris
• Lens (front part)
• Sclera (partially)
   

These analyzers provide detailed, high-resolution 3D images, allowing clinicians to assess the structure, shape, and depth of these tissues for diagnosis, treatment planning, and monitoring of ocular diseases or conditions.

Imaging Modalities Used 

• OCT (Optical Coherence Tomography) – Uses light waves to generate cross-sectional images.
• Scheimpflug Imaging – Uses a rotating camera and slit light source to create 3D reconstructions.
• AS-OCT (Anterior Segment OCT) – A specialized version of OCT optimized for the anterior eye.

What It Can Measure or Analyze:

• Corneal thickness (pachymetry)
• Anterior chamber depth and volume
• Corneal curvature (topography/ tomography)
• Angle assessment (for glaucoma risk)
• Iris configuration
• Contact lens fitting evaluation
• Post-surgical evaluation (e.g., LASIK, cataract surgery)

Common Uses: 

• Screening and monitoring glaucoma
• Planning for refractive surgeries (e.g., LASIK, PRK, SMILE)
• Cataract surgery planning
• Keratoconus detection and progression tracking
• Fitting specialty contact lenses (like scleral lenses)
   

Intelligent Analysis of Eye Subtleties for Advanced Ophthalmic Diagnosis

• Generates 28 / 60 / 100 ultra–high-definition Scheimpflug images of the eye’s anterior segment, capturing its intricate details 
• Delivers a profound level of analysis with 107,520 / 230,400 / 384,000 data points collected per scan.
• Backed by a growing global database of approximately 3,000 clinical cases, continuously expanding its diagnostic precision.
   

The Scansys ECT1 is crafted for excellence across multiple key ophthalmic scenarios:

• Refractive Surgery
• Refractive Cataract Surgery
• Contact Lens Fitting
• Glaucoma Screening
• ICRS (Intrastromal Corneal Ring Segment) Surgery
• Keratoconus Analysis
   

Unlock detailed insights with features like:

• Refractive 4 Map 
• Corneal Thickness Spatial Profile (CTSP)
• Percentage Thickness Increase (TCI)
• Anterior & Posterior Keratoconus Index (KCI)
• Case Reference Models, SVM Classifier, Keratoconus Probability (KCP), and Grading (0–IV)

Use Binocular Contrast to compare both eyes for early detection of asymmetric onset or track progression over time.

• ICL Size Recommendation & Vault Prediction: Leveraging corneal diameter, curvature, thickness, anterior chamber depth, and angle to recommend optimal ICL size and anticipate vault.
• Post‑surgical Vault Measurement: High-definition imaging at any angle to precisely measure the vault post‑ICL implantation.
   

• Captures up to 8th-order Zernike aberration data for anterior/posterior surfaces and the entire cornea within a 12 mm diameter.
• Visual simulations via Retinal Imaging, Point Spread Function (PSF), Modulation Transfer Function (MTF), enhancing both pre‑ and postoperative visual planning.
   

Break down complex corneal topography into clearly quantifiable components:

• Spherical
• Decentration
• Regular Astigmatism
• Irregularity

Supports more accurate and personalized refractive surgery planning.

• Provides critical metrics such as SimK, Total Corneal Power, True Net Power, Total Corneal Astigmatism, Spherical & Higher-Order Aberrations, posterior-to-anterior radius ratio, Kappa & Alpha angles 
• Includes built-in calculators for astigmatism and spherical aberration optimization by age, enabling advanced IOL customization.
• Supports IOL power calculations with formulas like Pearl‑DGS (optional), Jin, SRK‑T, Holladay 1, Hoffer Q, plus manufacturer-specific IOL data.
   

Analyzes gray values from cross‑sectional and longitudinal images to facilitate cataract surgical planning and intraoperative strategies.

• Orthokeratology Fitting: Measures corneal curvature, sagittal height, and eccentricity (nasal, temporal, inferior, superior; multiple diameters from 2 mm to 10 mm) 
• Lens Simulation: Customizable lens database with 3D/2D simulation under slit-lamp imaging to visualize fluorescence fitting, especially beneficial for orthokeratology lens fitting efficiency.
• Automatic Parameter Calculation: Derives fitting parameters for orthokeratology, soft, and RGP lenses based on individual corneal metrics.
• Optional Scleral Lens Module: Captures up to 60 high-definition Scheimpflug images over a 16 mm corneoscleral area, delivering a 360° panoramic sagittal height map and 13 essential fitting parameters—eliminating the need for multiple scans or image stitching.
   

• Measures parameters like Angle Opening Distance (AOD) and Trabecular-Iris Space Area (TISA), producing trend curves of chamber angle distribution and linearly fitted profiles.
• Reports Anterior Chamber Angle, Volume, and Depth, supporting early glaucoma detection and post-laser iridectomy evaluation.
• Includes five IOP correction formulas based on corneal thickness, allowing more accurate assessment of intraocular pressure.
   

Offers comprehensive parameters for creating corneal stromal ring tunnels—usable with manual or femtosecond laser techniques—enhancing surgical predictability and reducing complications.
