Posterior capsular opacification (PCO) is a primary complication after phacoemulsification combined with intraocular lens (IOL) implantation, which attributed to adhesion, proliferation, and migration of residual epithelial cells on IOL. Although surface hydrophilic coating considered be powerful way inhibit PCO incidence surgery, it requires complex post-production processes, thus limiting their applicability. In comparison, bulk modification stable, effective, facile IOL synthesis method for prevention. Herein, new anti-adhesive material was designed successfully synthesized by radical copolymerization ethylene glycol phenyl ether methacrylate (EGPEMA) 2-(2-ethoxyethoxy) ethyl acrylate (EA). The physicochemical properties P(EGPEMA-co-EA) copolymer materials, including chemical structure, mechanical, thermal, surface, optical properties, were analyzed using 1H NMR spectroscopy, FT-IR tensile test, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), water contact angle measurement, UV–vis spectroscopy. elongation at break the modulus elasticity tunable through change composition monomers. Compared other components, results showed that materials (70% EGPEMA in mass ratio, F7) are suitable preparation foldable lower elastic higher break. TGA DSC has high thermal stability, glass transition temperature F7 16.1 °C. measurement introduction EA improved hydrophilicity material. percentage transmittance all copolymers 400–800 nm above 85%. Then, biocompatibility evaluated vitro assay subcutaneous implantation. Both implantation experiments exhibited good anti-adhesion effect no cytotoxicity. Finally, performed, vivo confirmed prevention ability as well materials.

This paper reviews the latest trends and applications of silicone in ophthalmology, especially related to intraocular lenses (IOLs). Silicone, or siloxane elastomer, as a synthetic polymer, has excellent biocompatibility, high chemical inertness, hydrophobicity, enabling wide biomedical applications. The physicochemical properties are reviewed. A review methods for mechanical vivo characterization IOLs is presented prospective research area, since there only few available technologies, even though these vital ensure medical safety suitability clinical use, if long-term function considered. represent permanent implants replace natural lens correcting vision, with first commercial foldable made silicone. Biological aspects posterior capsular opacification have been reviewed, including effects implanted IOL. However, certain issues still challenging some conditions can prevent its application all patients. nanotechnology solutions Surface modifications an efficient approach further improve biocompatibility enable drug-eluting function. Different surface modifications, coatings, provide treatments various diagnoses through incorporation sensory functions. It essential that IOL optical characteristics remain unchanged case drug nanoparticles it. trials advanced technologies missing, thus preventing their at this moment.
