enVisus® and iTrace Join Forces for Next-Level Lens Design
April 2025 - Go to enVisus Overview
In specialty lens manufacturing, the goal is to deliver the best possible vision for every patient. But even the most advanced designs can leave some struggling with glare, halos, or lingering blur. Often, the cause is Higher-Order Aberrations (HOAs), subtle distortions in the eye’s optics that standard corrections can’t fix. Correcting HOAs used to be the domain of research labs and elite practices. Today, with the integration of iTrace by Tracey Technologies and FocalPoints’ enVisus®, this level of customization is not only clinically accessible, it’s manufacturing-ready.

Optimizing Outcomes with Ray Tracing
Ray tracing is essential in custom contact lens design because it enables precise optical modeling of how light interacts with the lens and the eye. The iTrace Ray Tracing Aberrometer utilizes true ray tracing, measuring the actual paths of multiple individual light rays as they travel through the eye's optical system, rather than relying on wavefront approximations or mathematical estimations. Unlike traditional aberrometry, which assumes a uniform wavefront, iTrace sends parallel light rays into the eye and precisely tracks their position when they reach the retina. This approach allows for a highly accurate assessment of aberrations, visual quality, and optical performance, making it a powerful tool for scleral and soft custom contact lenses.

When Ray Tracing Goes Full Circle
FocalPoints’ enVisus® was built with one thing in mind: bringing higher-order correction into everyday lens manufacturing without disrupting established workflows. And it’s not by chance. FocalPoints pioneered the use of ray-tracing technology in lens design as early as the 1990s, long before anyone else. That same physics-driven approach underpins all our advanced features today, from optical modeling to HOA compensation, making our integration with iTrace a natural fit.
The enVisus® platform extends your existing designs with an advanced layer that incorporates HOA correction into your lenses, based on precise diagnostic input coming from the iTrace aberrometer. By tracking the passage of light through different materials and curvatures, iTrace Ray Tracing data helps optimize lens parameters such as power, thickness, and alignment with the corneal and scleral surfaces. This ensures better visual quality, minimizes aberrations, and enhances patient comfort, making it a critical tool for designing custom-fitted lenses for irregular corneas and complex refractive errors.

From Measurement to Market-Ready
Labs can count on enhanced lens performance without reinventing their process, thanks to seamless integration with next-gen diagnostic tools through the combined power of iTrace and enVisus®:
- A practitioner captures a complete HOA profile using iTrace
- The iTrace data is saved in a format readable by enVisus®
- enVisus® processes the HOA map and applies the optics onto the lens design
- The design is manufactured using your existing tools and workflow
This integration transforms complex optics into standardized, scalable corrections, making wavefront-guided lenses a practical reality across your portfolio.
Transforming Vision Care for Everyone
For Manufacturers embracing HOA-capable lenses is more than just a technical upgrade; it’s a strategic opportunity to position your lab at the forefront of innovation. By leveraging data already accessible to your prescribing ECPs, you can introduce high-performance optics into your product line without the need to overhaul your existing design platform.
For Practitioners using an iTrace instrument, there’s untapped potential waiting to be unlocked. Moving beyond standard correction methods, you can deliver a more advanced level of care by addressing the underlying causes of poor visual quality. With objective, data-driven insights, you can tailor each solution more precisely to the individual needs of your patients.
For Patients HOA-optimized lenses offer sharper, more natural vision that can dramatically improve daily life. For individuals with complex visual conditions such as keratoconus, post-refractive surgery outcomes, or post-transplant eyes—the improvement is not just visible, it’s transformative.

Precision Meets Production
The combination of iTrace’s diagnostic power and enVisus® practical approach is more than a technology match, it’s a production-ready pipeline for better lenses and better outcomes. Whether you’re looking to expand your custom lens portfolio or elevate the visual quality of your current designs, this integration offers the tools and the confidence to get there.
We believe that true innovation happens when cutting-edge diagnostics and intelligent design come together. Our collaboration with Tracey Technologies and the integration of iTrace data into the enVisus® platform reflects our ongoing commitment to helping manufacturers deliver truly personalized lenses — not just in theory, but in everyday practice.
