MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202541034754 A) filed by National Institute Of Technology, Warangal, Telangana, on April 9, for 'aqueous flow influenced by a perforated iris-fixated intraocular lens in a partial porous domain.'
Inventor(s) include Ajay Kumar; A Benerji Babu; M. R. Flarence; Raghu Raja Pandiyan K; and Sivaprakash S.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "Disclosed is a phakic intraocular lens (pIOL) (100) for implantation in the anterior chamber (112) of a human eye, configured to correct refractive errors while facilitating aqueous humor flow. The pIOL lens (106) includes at least one perforation, which may be a central hole at the geometric center or two symmetrically positioned side holes along the lateral axis of the lens body. These perforations (106) enable controlled aqueous humor exchange, thereby reducing intraocular pressure and improving fluid dynamics for ocular health management. Additional features include an ultraviolet (UV) filter for retinal protection, a biocompatible material composition for long-term implantation, and a specific perforation diameter range for optimized fluid flow. Also disclosed is a method (200) for improving ocular fluid dynamics and managing intraocular pressure, which involves customizing the pIOL lens (106) and utilizing computational fluid dynamics (CFD) for perforation placement optimization."
