Description

The HUVITZ HTG-1 Topography System utilizes advanced Placido disc analysis technology to provide reliable, accurate corneal measurements. Offering comprehensive data, it is an essential tool for assessing the shape, health, and functionality of the cornea. Whether you’re evaluating corneal health, planning for cataract surgery, or determining lens prescriptions, the HTG-1 delivers precise results that aid in critical decision-making.

Accurate Corneal Data Measurement
The HTG-1 uses Placido disc analysis to measure a variety of critical corneal parameters, providing detailed insights into corneal shape and health. The system measures:

• • Keratometry
  • Topography
  • Keratoconus risk
  • Zernike Coefficients
  • Pupillometry
  • White-to-white measurements
    The resulting data is presented in multiple formats, including Axial, Tangential, Refractive Power, and Elevation Maps, making it easier to assess the cornea’s overall condition and plan appropriate treatments or prescriptions.

Early Detection of Keratoconus
The HTG-1 analyzes the front curvature, regional shape, convexity, and eccentricity of the cornea to calculate the Keratoconus Prediction Index (KPI). This index helps predict the likelihood of keratoconus, providing early warnings for the condition and assisting in proactive management.

Zernike Analysis for Comprehensive Evaluation
By analyzing Zernike Coefficients and Zernike Maps, the HTG-1 offers in-depth data on various refractive parameters, including:

• • Refractive power variations
  • Irregular astigmatism
  • Eye aberrations
    This data is essential for assessing complex refractive conditions and customizing treatment plans.

Pupillometry for Comprehensive Pupil Assessment
The HTG-1 features pupillometry to measure pupil size and responsiveness under both day and night conditions. It graphically displays key data such as:

• • Pupil diameter
  • Maximum average pupil diameter
  • Average pupil diameter
    These measurements are important for evaluating visual function, especially in low-light conditions and for patients considering refractive surgery.
