Poly(2-Hydroxyethyl Methacrylate) Hydrogels for Contact Lens Applications–A Review

The emerging technology in biomedical engineering requires biocompatible materials, which are also referred to as biomaterials. For a material be considered biocompatible, it should not interact with human tissues harmful way, and vice versa. Various properties of such mechanical optical properties, have for different applications. One the most popular applications biomaterials is contact lenses. Hydrogels, specifically poly(2-hydroxyethyl methacrylate) (PHEMA) hydrogels, among ones ophthalmologic applications, especially soft This paper reviews use PHEMA hydrogels one important possible manufacturing process lens addressed. Many studies shown that possess many advantages promising development prospects.
