Bio Break: Tooth-In-Eye Surgery

Sector: Surgical
Topic: Bio Break

In this episode of Bio Break, Nick Allan and Joris van der Heijden dive into one of the most astonishing medical innovations we’ve ever come across: osteo-odonto-keratoprosthesis. Or, as Nick quickly dubs it, “tooth in eye surgery.”

This fascinating procedure sounds like science fiction but has been successfully used to restore vision in people who are blind due to damage in the front part of the eye, such as from trauma or autoimmune diseases. While the retina remains functional, traditional options are off the table. That’s where this extreme innovation comes in.

Joris explains how the procedure starts with removing a patient’s tooth and some surrounding bone to create a small square-shaped structure. A hole is drilled in the center, and a tiny lens is implanted, this piece will eventually act as an artificial cornea. But before it’s implanted into the eye, it needs to be biologically prepared. That’s done by temporarily placing the implant into the patient’s cheek, where it can become vascularized over a few months.

Once ready, the patient returns to the hospital for the second stage. Surgeons retrieve the now-living implant from the cheek and carefully insert it into the eye, replacing the damaged corneal area. Thanks to the previously grafted oral tissue, the eye is prepped to accept the implant, and the result is stunning: restored vision in up to 90% of patients.

Even more impressive? Around 50% of these individuals gain high-quality vision, enough to read or even consider driving.

Whether you’re a medtech enthusiast or just love mind-blowing medical stories, this episode is a must-watch. Learn how combining dental tissue, ocular surgery, and a bit of clever biology can give people their sight back.

Nick Allan and Joris van der Heijden revisit one of StarFish Medical’s most successful Pathfinder journeys, showcasing how a bold research concept evolved into a fully realized clinical diagnostic device.

A visual project roadmap titled "Finding the Path to MedTech Innovation" shows five development phases: Phase Zero (Pathfinder Product Definition), Phase One (Engineering Detailed Design), Phase Two (Transfer), and Phase Three (Manufacturing). Each phase includes activities such as contextual research, usability engineering, IP generation, design input development, regulatory strategy, prototyping, verification, manufacturing process development, and volume manufacturing. Arrows represent workflows across multiple functions like product development, quality, and regulatory support, with milestone gates marked by stars.

Nick and Joris explore one of the most dynamic early-phase services at StarFish Medical: the Pathfinder Program. If you’re a medtech innovator with a promising concept or prototype, Pathfinder helps you identify the right path forward—before you invest millions in development.
