Corneal topographer iTrace Prime

wavefront aberrometer

Overview
iTrace Prime is the Version 7 release of the iTrace ophthalmic analysis platform. The update introduces new displays and algorithms, improved imaging and wavefront capture, enhanced navigation between views, batch save/print capabilities, and expanded Toric Planner customization. iTrace Prime delivers integrated anatomical and optical information from a single, rapid acquisition to support clinical assessment and IOL selection.

Key features

• Version 7 (iTrace Prime) adds new displays and refines imaging and wavefront capture algorithms.
• Proprietary Ray Tracing visual analysis for objective measurements of visual quality and optical performance.
• Improved navigation between displays, plus batch saving and batch printing to streamline documentation.
• Enhanced Toric Planner and Toric Check workflows for toric IOL planning and verification.

New and highlighted displays

• Tear Film Index (TFI): proprietary algorithm that records the ocular surface up to 12 seconds after a blink, analyzes Placido ring image sharpness/shape/continuity during tear film evaporation, and outputs a 0–10 index quantifying the tear film’s impact on visual quality.
• Prime Dashboard: consolidates multiple indices (Dysfunctional Lens Index (DLI™), Corneal Performance Index (CPI™), Quality of Vision Index (QVI™)), separates corneal from internal optical performance, reports each on 0–10 scales, and provides a combined 0–10 whole-eye quality metric.

Previous features retained and enhanced

• Dysfunctional Lens Index (DLI™) to assist in assessing lens dysfunction and timing for lens replacement.
• Toric Planner and Toric Check for accurate toric IOL calculation and post-operative verification.

Improvements and workflow

• Refined imaging quality and wavefront capture for increased measurement precision.
• Batch saving and batch printing for efficient reporting and recordkeeping.
• Optimized display navigation to accelerate clinician review of combined metrics and images.
