Let The Robot Handle It

You are an eye care practitioner trying to prescribe the perfect Ortho-k lens for your patient. You have two options: easy-to-fit lenses that lack customization or fully customized platforms that require extensive training and experience.

But what if there was a third option? A solution that combined the convenience of easy-to-fit lenses with the customization of fully customized platforms?

That’s where KALCULUS comes in. Using advanced algorithms and artificial intelligence, KALCULUS automatically creates fully customized lenses for each unique cornea, providing the exact treatment outcome your patient needs, eliminating the need for a steep learning curve.

With KALCULUS, you can offer your patients a superior Ortho-k experience that’s simple, elegant, and effective. 

The KALCULUS Solution

You have a patient with a complex corneal shape that requires an Ortho-K lens for effective management. You’ve tried multiple lens designs and adjustments, but nothing seems to work. It’s frustrating for both you and your patient.

That’s where KALCULUS comes in. Our algorithms and powerful calculator work together to obtain an optimal fit, down to the micron.

But what truly sets us apart is our AI function that recognizes troubleshooting patterns and makes automatic adjustments for a better fit outcome. It’s like having an Ortho-K specialist right by your side, guiding you through the treatment program.

We understand that every patient is different and requires personalized care. That’s why we offer four different groups to choose from, based on your patient’s needs: myopia control, regular adults without presbyopia, adults with presbyopia, or post-laser correction. All you need to do is input some baseline parameters, and we’ll take care of the rest.

We are here to help you design your lenses so that you can focus on your patients. 


Our Goal

At KALCULUS, we believe in empowering practitioners to provide their patients with the highest level of care. By eliminating the challenges and complexities of lens designing and troubleshooting, we enable practitioners to focus on building meaningful relationships with their patients. Our mission is to help practitioners do great work that their patients truly deserve, so that everyone can experience the benefits in their lives.
