New York Patent of the Month – January 2024
Clerio Vision, Inc. is utilizing high-energy laser technology to further the field of contact lenses, pushing the boundaries of what’s possible in ocular enhancement. Their revolutionary method, as claimed in a newly granted patent, transforms optical devices, such as contact lenses, intraocular lenses, or corneal inlays, using a focused, visible or near-IR laser. The goal? To enhance visual performance in ways previously unimaginable.
The patented method involves precise modifications to the refractive index of optical polymer material, creating refractive structures that exhibit a change in refractive index without observable scattering loss. This is achieved by irradiating select regions with a high-repetition, low-pulse energy femtosecond laser, a technological marvel in itself.
One remarkable application is the creation of refractive structures on curved contact lenses ex situ relative to the patient. This approach minimizes surface shape changes or distortions, offering a new dimension to personalized vision correction. The refractive structures can be intricately patterned, providing diverse optical corrections, including sphere, cylinder, multifocality, or depth of focus adjustments.
What sets Clerio Vision’s method apart is its versatility. Whether it’s employing Fresnel lens or diffractive patterns, inducing shape changes for ballast functions, or dynamically altering prescriptions over time, the potential applications are vast. The induced shape changes can even reduce astigmatism or higher-order aberrations, showcasing the depth and precision of this innovative technology.
The patent outlines methods for in-situ modification of refractive properties, allowing real-time adjustments and corrections. The use of gradient index (GRIN) layers and the dynamic alteration of patterns provide a level of customization previously unattainable.
Clerio Vision’s invention is not just about correcting vision; it’s about reshaping the future of vision correction. With a focus on minimizing shape changes, dynamic adjustments, and versatile applications, this patented method is a testament to the company’s commitment to pushing the boundaries of what’s possible in ocular science.
