Special Features are proprietary FocalPoints features designed to simplify the work of contact lens designers. They are exclusive to FocalPoints and offer significant advantages over traditional methods by providing powerful tools that speed up their workflow and eliminate the need for complex calculations.
By utilizing these advanced features, specialty contact lens designers gain access to a set of possibilities that would typically require extensive time and effort to achieve, or may even be impossible to attain without the aid of FocalPoints. These features open up new avenues for creativity and efficiency, allowing lens designers to achieve outstanding results in a fraction of the time it would take using conventional methods.
Ray-tracing is used to simulate and analyze how light rays interact with the cornea, contact lens, and the eye's anatomy to determine the optical performance of the contact lens. Many of our Special Features harness the power of Ray Tracing technology, enabling you to create contact lenses with unparalleled accuracy and clarity.
The High Definition tool employs the advanced Ray Tracing algorithm to generate a free-form Power Curve without spherical aberrations. This cutting-edge approach ensures an unparalleled level of accuracy and clarity in the resulting Power Curve output.
enVisus® aims to revolutionize the world of specialty contact lenses by correcting Higher-Order Aberrations (HOAs) across any lens design without altering the usual FocalPoints manufacturing processes, introducing a transformative approach developed through years of dedicated research.
The Decentered Conic displaces a conic curve by a specific distance, resulting in a shape reminiscent of a pointed dome. It delivers a Symmetrical multifocal when applied to a symmetrical design or a Toric multifocal when applied to a back toric design.
The lens designer can effortlessly define a Multifocal Add profile by intuitively sketching it on a graph. FP Designer leverages the power of the Ray Tracing algorithm on the front surface to precisely compute the desired Multifocal profile.
The Segemented Bi-Focal utilizes translation to achieve a bifocal effect. As a result of the varying curvatures, the near and far zones exhibit a step at the segmentation line. To ensure a seamless transition, this step is smoothed using an S-curve transition, which provides a gradual and visually appealing blending of the two zones.When using the HD version, the software generates an aberration-free surface.
The Parametric D-Map can create three distinct types of Segmented Bifocals, offering increased versatility. This tool generates the Bifocal zone by creating a three-dimensional Add map, which is then utilized in conjunction with the Ray-tracing algorithm to produce the final lens. This approach provides greater flexibility, allowing for enhanced customization and adaptability.
The FP Prism tool adds weight to the lens while limiting the amount of prismatic aberration. Depending on the specific lens design, the FP Prism approach may yield a thinner lens compared to other kinds of prism stabilization. When using the HD version, the software generates a Prism using the Ray-tracing algorithm, obtaining an high definition lens.
The KC Niche offers a specialized solution for individuals with Keratoconus. The KC Niche involves a spherical segment carved into the back surface of the lens, serving the dual purpose of accommodating the irregular corneal shape associated with Keratoconus while also limiting the thickness of the tear layer, and incorporating HD optics.
The Edge Vault allows to accommodate the presence of a pinguecula. The Edge Vault applies a spherical ridge to the lens' edge, allowing for a customized fit and enhanced comfort. Depending on the specific cases, a lens can feature one or two Edge Vaults to address the individual's needs. Each Edge Vault is defined by its Center, Diameter, and Height in µm, ensuring precise adjustments.
The Smooth Edge tool offers a solution for achieving a smooth and polished edge on the lens. However, achieving this requires careful consideration of the lens design. It involves not only adjusting the settings in the Specifications dialog but also specifically defining the Lenticular region, configuring the program responsible for generating the data file for the lathe and having the specific Tool on the Lathe.
Fenestrations provides the capability to drill multiple fenestrations on a lens. This functionality allows for the creation of fenestrations while the lens remains on the machine, enabling a convenient and efficient workflow. However, in FocalPoints, a fenestration is not limited to a single "hole" in the lens. Instead, it represents a series of "holes" that are strategically drilled around a ring, offering enhanced customization and precise placement.
