What is Orthotool?

The ULTIMATE Contact lens design software

  • More designs including 5 Controlled Clearance™ Orthokeratology Designs.
  • Virtually everything you need on one convenient screen.
  • Easy to use with keratometry or corneal topography.
  • Resolve cross cylinders over refractions with our Toric Soft Lens Calculator.
  • Design a wide variety of RGP lenses faster and more reliably.

Orthotool™ is the current iteration of contact lens design, modeling, and manufacturing software which has evolved over the last 25 years. Our current software allows contact lens fitters to enter traditional patient information (K’s and spectacle Rx), suggests the presence of certain pathology, makes lens design suggestions, and allows the user to “point and click” a number of different lens designs and fitting techniques. Once a design is selected, Orthotool performs the optical calculations, displays the complete lens parameters and manufacturing data, displays a cross section model of the lens and a lens thickness profile, and graphs the tear film thickness across the lens diameter.

Orthotool eliminates vertex conversion, “SAM FAP”, “RALS-LARS”, and other optical calculations, bringing standards and consistency to your contact lens designs and reduces refits and training costs. Orthotool makes sense out of detailed lens parameters and presents information in a way that is easy to visualize and lets anyone understand complex lens designs and fitting concepts.

Orthotool is programmed with standard spherical lens designs, ultra thing, aspheric, bitoric, and reverse geometry lens designs. It also includes alternate peripheral curve systems that can be applied to virtually any lens design. Our Lens Design Tuners allow you to customize many of the designs to suit your individual fitting preferences and helps you achieve the best lens performance for your patients.

What our customers say

I have found Orthotool to be extremely valuable in helping me understand the construction and design of RGP lenses. It has also been able to help me control some lab costs with complicated lenses like ortho-k, multifocal and post-RK fits.
Dr. Mark J. Page, OD
Our Contact Lens Specialty Service at Pacific University uses the Orthotool lens design software on a daily basis for many of our normal and complex patients that require customized rigid lens designs. The ability to clearly visualize each GP lens parameter has brought a new level of fitting clarity and success to our practice. The versatility of the Orthotool software is simply incredible.

I have been an Orthotool user for about 10 years and it has been one of the best investments in our practice. I still use OK lenses designed from other OK manufactures but you are in control of the lens design each and every time with Orthotool. I highly recommend it for anyone who incorporates orthokeratology in his/her practice!
Jiyen Shin, OD, FOAA
The Ortho Tool software purchase was the best invesment that I ever made practicing ortho-K along with the trial set to define the lens design. I have been using Orthotool for the past few years for most of my initial Ortho-K fitting and the success rate improved in a great deal when the diagnostic fitting was incorporated. It is a great tool as a learning guide also and I do play around with the parameters to determine the changes in tear film profile. The tear film profile is a great way to visualize the tear volume under the complex lens design and allows to manipulate all the curves for any changes. I have been using this software for the aspheric and the multifocal designs also. As an orthokeratologist, this software is the MUST- TO- HAVE to enjoy the designing your own lenses and also as a learning tool.
