The U.S. Patent and Trademark Office will issue a fundamental patent to OptiMedica related to laser cataract surgery technology, according to a company news release.
Patent No. 8394084, to be issued March 12, will cover a three-dimensional femtosecond laser system that can be used during cataract surgery to perform anterior capsulotomy and laser fragmentation, the release said.
The Catalys system combines a femtosecond laser with integrated 3-D optical coherence tomography and pattern-scanning technology. Studies have demonstrated the system can deliver a high degree of accuracy and repeatability, with incision accuracy within tens of microns. The system also reduces cumulative dissipated energy during ultrasound phacoemulsification by about 99%, resulting in a gentler disassembly of the lens, according to a previous press release from OptiMedica.
OptiMedica has filed additional requests for patent protection related to the Catalys system and underlying technologies. The company has more than 30 pending U.S. patents and more than 25 pending international patents along with five issued international patents, according to the release.
Catalys gained CE mark approval for use in cataract surgery in September 2011 and U.S. Food and Drug Administration approval in December 2011.
