DESIGNING

At the core of the focal points system is FocalPoints Designer, which allows you to create the rules that define a lens design, set materials and machining characteristics, import and export saved designs. There are also a wide array of tools for visualizing the finished lens both on and off the eye.

Designer is a real CAD dedicated to contact lens design, it's not just a collection of predefined designs. The lens designer can develop his own innovative designs. Designer is natively based on the "cornea-to-lens relationship". The lens back curve can be defined by stating the clearances with the cornea; this method leads directly to an automatic self-fitting procedure.

Geometries are described by discrete vectorial representation. Each point is defined by cylindrical coordinates and the normal vector. Designs are defined component-wise and can be re-used in other designs. Designer has advanced tools for simulated testing, essential for development work. In FocalPoints Ray Tracing is directly integrated.


USE A VAST ARRAY OF TOOLS

FocalPoints has a number of powerful tools for visualizing lens optics and geometry that allow you to find problems or fine tune a design before it goes to the lathe. In addition to traditional spheres and conic sections, FocalPoints offers arcs, Bezier curves, splines, and automatic blending curves.

Users can enter their own formulae using a formula editor similar to that found in many popular spreadsheets programs. Lens data may also be saved in the form of tables. Any table or formula can draw on a number of lens parameters such as diameter or base-curve. Tables, formulas, edge designs, or other lens elements can be saved to disk and used in other lens designs.


DESIGN AND FIT CUSTOM LENSES

If a lens has been designed to be adaptive it can be automatically fit to topographic data. FocalPoints can read and interpret the data of many popular corneal topographers.

  • CSO
  • Humprey
  • Eaglet ESP
  • Keratron Scout
  • Medmont E-300
  • Nidek Magellan & OPD Scan
  • Shin-Nippon
  • sMap3D
  • Tomey

The fit is reviewed with an accurate, interactive simulated fluorescein pattern and a diagram of the tear layer. After fitting a lens to topographic data, the lens can be fine-tuned for a perfect fit by clicking the control points on the tear layer diagram.

INTEGRATED SIMULATED TESTING
GRAPHICS MODULE

The Graphics Module is an advanced drawing and imaging tool, which helps create technical documentation.

Being integrated in Designer, all lens design parameters, geometry and sections can be automatically generated from the design definition. To assure the best possible display and printing, drawings are treated in vector format. The user can even create Templates to be used with different designs or for different purposes.

LENS DESIGN LICENSING

Design Licensing

Once you have developed a lens design, your work can be distributed to any other Focal Points user in a secure encrypted file. You set the duration of the license and decide which parameters the Licensees have access to.

The Design Owner can decide which of the various visualization tools and graphs can be hidden from the user, as well as any tables or formulae used in the design. Software on the lathe prevents unauthorized duplication of sensitive lens data files and keeps track of the number of lenses cut.

In order to protect a design and issue a License, one must have the Design Owner Toolkit, which assigns to the Licensor an unique Owner Code, defines the list of protected Classes, defines the visualization criteria, enables the protection and finally issues the design license.
