    Abstract: The invention is related to a disposable contact lens comprising a top coating which is made of a hydrophilic polymeric material including dangling hydrophilic polymer chains covalently linked to the hydrophilic polymeric material through oligo-caprolactone linkages susceptible to enzymatic degradation in the eyes. The top coating is stable to lens processing/storage and confers lubricity to the lens. However, it slowly is degraded during the lens wear due to the action of enzymes (e.g., Lipase) in tear film. The loss in lubricity will be experienced as a drop in comfort for the lens wearer and thereby serves as the built-in compliance features of the disposable contact lens.

    Abstract translation: 本发明涉及一次性隐形眼镜,其包括由亲水性聚合材料制成的顶部涂层,其包括通过易于在眼睛中酶促降解的低聚己内酯键与亲水性聚合物材料共价连接的悬浮的亲水性聚合物链。 顶部涂层对透镜加工/储存稳定,并赋予透镜润滑性。 然而,由于在泪液膜中的酶(例如脂肪酶)的作用,它在镜片佩戴期间缓慢地降解。 润滑性的损失将作为镜片佩戴者的舒适度降低,从而用作一次性隐形眼镜的内置柔顺特征。
