Recently, the innovative product "aspheric diffractive multifocal intraocular lens" produced by Eyebright Medical Technology (Beijing) Inc. is approved for marketing.

　　The aspheric diffractive multifocal intraocular lens is a one-piece/posterior chamber intraocular lens, which is a foldable modified L loop. The main part and supporting part of the product are made of the copolymer of ethyl acrylate and ethyl methacrylate, added with ultraviolet absorber, and the surface is modified with heparin. The innovation of this product is that its optical part adopts the design of combining diffraction-splitting and non-spherical surface, which enables multi focus through the diffraction technology, and therefore it becomes the first in China.

　　This product is used for vision correction of adult cataract patients. It is expected to provide far and near focus, which to some extent makes up for the poor vision of single focus intraocular lens. The marketing of this product brings new treatment options to patients.

　　The NMPA will strengthen the post-marketing surveillance of the product to protect the safety of medical devices used by patients.
