'Antibacterial Artificial Intraocular Lens' Made with Semiconductor Technology

Successful Development of Antibacterial Artificial Intraocular Lens Applying Nano Patterns and Ionic Polymer Thin Films

[Asia Economy Reporter Junho Hwang] An antimicrobial intraocular lens utilizing semiconductor process technology has been developed. This intraocular lens is coated with an ionic polymer thin film, which reduces damage to ocular cells while eradicating pathogenic bacteria. It is expected to enhance the success rate of intraocular lens implantation surgeries for cataracts.

The Nano Convergence Technology Institute announced on the 6th that it has succeeded in developing an antimicrobial intraocular lens that reduces surgical side effects by applying semiconductor process technologies such as nanopatterning and ionic nanopolymer thin films. The related research paper was featured as the cover article in last month's issue of the international journal Advanced Healthcare Materials.

The research team developed an intraocular lens with properties that reduce ocular cell damage and eradicate pathogenic bacteria by using a polymer nanopattern with elasticity approximately 500nm in size, created through semiconductor process technology (Bio-MEMS). This lens also reduces postoperative lens opacity and prevents infection complications caused by pathogenic bacteria.

Dr. Kyungkyun Lee, who led this study, stated, "Based on this developed research outcome, we will conduct additional studies to ensure safety for human implantation and plan to pursue commercialization through technology transfer."

Director Jowon Lee said, "With the institute’s semiconductor infrastructure and nanobio process technology, we will actively support excellent research outcomes to lead to the commercialization of nano-medical devices for human implantation in the future."
