Keranova unveils its FemtoMatrix technology

It is the first time that a new surgical technique, Photoemulsificationwas used which represents a major new step in cataract surgery since the invention of phacoemulsification in the late 1980s. These particularly positive results will benefit both surgeons and patients. Explanations.

The Keranova company conducted a study at the end of the second quarter of 2022 in the Czech Republic on a total of 54 patients. The contralateral eye of each patient was treated with phacoemulsification to serve as a control.

The study showed that by using the FemtoMatrix technology, in the vast majority of cases, ultrasound could be dispensed with in a standard population or at least significantly reduce its use.

Surgeons will thus be able to perform perfectly calibrated operations for cataracts and thus limit the risks associated with the use of ultrasound during phacoemulsification.

With this new technology, they can now operate without ultrasound as effectively as with current techniques and with increased precision and reduced risk of corneal or iris damage, capsular rupture or adverse effects on the retina, while maintaining the same operative time “Assures the press release from Keranova.

Patients (94 million people worldwide; a figure expected to increase as the population ages) will be able to benefit fromsafer, less operator dependent operation with more consistent results.

In practice, this surgical laser allows true photoemulsification of the lens rather than simply cutting into quarters or rods as suggested by current devices.

This system allows precise and automatic adjustment of the laser at each location on the lens, and the use of a surgical robot greatly simplifies the procedure.. Fast and easy to maneuver, the device fits easily into the operating room, eliminating the need for the surgeon and patient to move around during the procedure.

These exceptional results, achieved after six years of intensive work, will enable Keranova to soon offer PhotoEmulsification technology to surgeons. This will be the third generation surgical technique for cataracts, after extracapsular extraction and phacoemulsification “, explains Fabrice Romano, founder and CEO of Keranova.

And to continue: we will therefore be the first to provide surgeons with a medical device that meets the current technology standards used in cataract surgery, with an ultrafast laser, an element that modifies the laser as a result of photonics, a robot, artificial intelligence that automatically adjusts the energy and a fiber. In a nutshell, a device that uses today’s technologies to benefit cataract patients. »

The company’s innovative approach aims to transform cataract surgery by reducing manual procedures in favor of automation and precision to promote reproducibility and reduce clinical risks.

The results are extremely promising: the FemtoMatrix device has been shown to safely perform laser cataract surgery without phacoemulsification, in less than eight minutes in a single operating room, which is impossible with current techniques. adds Dr. Damien Gatinel, head of refractive surgery and anterior segment of the eye department at the Rothschild Foundation (Paris) and member of Keranova’s scientific council.

From now on Keranova aims to achieve CE marking for its device in 2023which will make it possible to market a first version of FemtoMatrix.

*Keranova develops next-generation surgical devices in ophthalmology using photonics-based technology to design ultra-fast medical lasers.
