Optimo Medical AG and Ansys transform eye surgery to better treat astigmatism

PITTSBURGH and BIEL, Switzerland, February 23, 2021 / PRNewswire / –

/ Highlights

  • Optimo Medical AG and Ansys Collaborate to Combine High-Fidelity Structural Simulations with Digital Twin Technology to Effectively Develop Patient-Specific Astigmatism Surgery Plans and Dramatically Improve Patient Vision
  • The collaboration also facilitates in silico clinical trials of new ocular products, enabling engineers to detect design flaws and reduce development costs.

To perform patient-specific eye surgery planning, dramatically improve vision and treat astigmatism, Optimo Medical SA and Ansys (NASDAQ: ANSS) integrate high-fidelity structural simulations with advanced digital twin technology into next-generation surgical preparation. Offering a solution that optimizes surgical precision to maximize patient outcomes, the collaboration also leads to in silico clinical trials of new ocular products, dramatically reducing development time and costs.

Providing care to 15 million patients with low cylinder astigmatism each year has traditionally required ophthalmologists to plan eye surgeries with widely common statistical patterns. This often caused suboptimal incision placement and imperfections in the correction of the patient’s vision, requiring multiple operations to resolve the issues. Integrating Ansys® Mechanical with Optimo Medical AG digital twin technology, ophthalmologists create identical digital copies of patient corneas to test surgical strategies for individual patients that dramatically improve outcomes.

“Before I started using Optimeyes, like all ophthalmologists, I was forced to work with one-size-fits-all statistical models, which frequently resulted in overcorrections. With Optimeyes I am now able to work on a patient specific approach, “said Dr. Johan blanckaert, ophthalmologist at the Oculus clinic. “Since then, I have achieved superior results, which means a life without glasses for my patients. Therefore, I consider the use of Optimeyes in surgical planning to be a real change in the industry. “

“Integrating Mechanical with Optimeyes allows ophthalmologists to perform virtual keratotomy astigmatism surgeries to improve the incision parameters of each patient. In addition, it equips surgeons with an advanced planning tool to treat low cylinder astigmatism during cataract surgeries and predict the outcome of the operation. Optimeyes also facilitates mechanical-based in silico clinical trials, allowing engineers to simulate new products, identify design flaws and save millions of dollars in development costs. ”

“In eye surgery, microns make the difference between a successful operation and disappointing results. Optimeyes uses Mechanical to guide eye surgery treatment planning, simulate the effects of physical interference, and improve patient outcomes, ”said Harald Studer, CEO, Optimo Medical AG. “Together with Ansys, we are leading the way for the large-scale adoption of engineering simulation within the eye care industry and rapidly treating astigmatism for millions of patients around the world. ”

“As the ophthalmic community harnesses simulation to provide personalized treatment, it is crucial to provide clinicians with simplified tools that speak their language,” said Prith Banerjee, CTO, Ansys. “The integration of Optimeyes with Mechanical provides a next-generation solution for ophthalmologists to effectively combat cataracts and low-cylinder astigmatism. This enables correct surgeries for the first time, helping people with visual impairments return to a better quality of life faster than ever before. “

About Optimeyes ™

Optimeyes ™ creates an identical digital copy of the patient’s cornea, based on the eye measurement data. With this “digital twin”, the software performs a virtual arcuate keratotomy surgery, in order to find the optimal and personalized incision parameters for each patient. This CE certified technology is based on tailor-made biomechanical simulations and does not depend on nomograms or statistical diagrams. Only Optimeyes ™ provides patient-specific in-silico planning for arcuate keratotomy to correct astigmatism during femtosecond laser cataract surgery [1]. About 75% of cataract patients have treatable astigmatism greater than 0.50D. Among these cases, three out of four belong to the category of low cylinders. [2][3] between 0.5 and 2.0D. The treatment of low cylinder astigmatism is important, because even a small cylinder of 0.5D equals a spherical error of 0.25D [4]. The core Optimeyes ™ technology is based on several scientific papers from Harald P. Studer [5][6][7][8][9].
