Artificial Eye Lens with Cavity Design for Reduced Incision Implantation - US12599477B2
Summary
USPTO granted patent US12599477B2 to Carl Zeiss Meditec AG for an artificial eye lens with front and rear lens elements connected by an intermediate element forming a cavity with an opening for liquid flow. The design allows reduction of the access incision necessary for implantation. The patent includes 15 claims and covers methods for production and implantation of the lens.
What changed
USPTO granted patent US12599477B2 to Carl Zeiss Meditec AG for an artificial eye lens comprising front and rear lens elements with positive optical power and an intermediate element forming a cavity. The cavity design includes an opening allowing liquid flow and maintains fixed distance between lens elements when implanted.
For competitors in intraocular lens manufacturing, this patent establishes intellectual property barriers around cavity-structured lens designs and associated implantation methods. Parties developing similar lens technologies should conduct freedom-to-operate analyses and consider licensing discussions with Carl Zeiss Meditec.
What to do next
- Monitor patent portfolio for competitive intelligence
- Review implementation considerations for intraocular lens products

Abstract
An eye lens having a front lens element and a rear lens element, which each have a positive optical power and an optical region, and an intermediate element, which is connected to the lens elements outside the optical regions so that the lens elements and the intermediate element form a cavity. The eye lens allows the width of an access incision necessary for implantation to be reduced. The eye lens includes the lens elements and the intermediate element that are shaped such that, in the implanted state, a distance between the front lens element and the rear lens element is fixed and the cavity has an opening which allows liquid to flow into the cavity. Embodiments of the invention include a method for producing such an eye lens and a method for implantation.
