The present invention relates to fumaric acid derivatives and ophthalmic lenses using them. More specifically, the present invention relates to a fumaric acid derivative having a hydrophilic group and a silicon-containing alkyl group within a molecule, and to contact lenses or intraocular lenses.
The fumaric acid derivatives of the present invention provide, on one hand, superior oxygen permeability by having a silicon-containing alkyl group within the molecular structure, and on the other hand, improved compatibility with other hydrophilic monomers by having a hydrophilic group within the same molecule. When ophthalmic lenses obtained by polymerizing monomer compositions containing the fumaric acid derivative are constructed as, for example, water content lenses, lenses with high oxygen permeability independent from the water content may be obtained, wherein the fumaric acid derivatives is superior in compatibility with the hydrophilic monomer used in combination and allows the combination in various mixing ratios.
本发明涉及富马酸衍生物及使用它们的眼科透镜。更具体地,本发明涉及一种分子内具有亲水基和含硅烷基的富马酸衍生物,以及接触镜或人工晶体眼镜。本发明的富马酸衍生物一方面通过分子结构内含有硅烷基,提供了优异的氧气渗透性,另一方面通过同一分子内含有亲水基,提高了与其他亲水单体的相容性。当通过聚合含有富马酸衍生物的单体组成物制备眼科透镜时,例如水含量透镜,可以获得独立于水含量的高氧气渗透性透镜,其中富马酸衍生物在与组合使用的亲水单体相容性方面优越,并允许以各种混合比例组合。
