    • The present invention is a process for forming ophthalmic devices such as contact lenses, comprising the steps of curing a reactive mixture comprising at least one silicone-containing component, at least one hydrophilic component and at least one protonated diluent or protonatable diluent having a Hansen solubility parameter, δp between about 2 and about 7 to form an ophthalmic device having an advancing contact angle of less than about 80°; contacting the ophthalmic device with an aqueous solution which is capable of changing the Hansen solubility parameter, δp of the protonated or protonatable co-diluent to enhance water solubility and removing said diluent(s) with said aqueous solution.
    • 本发明是用于形成眼科装置如隐形眼镜的方法,包括以下步骤:固化包含至少一种含硅氧烷的组分,至少一种亲水组分和至少一种质子化稀释剂或可质子化的稀释剂的反应性混合物,其具有Hansen溶解度 参数,约2至约7之间的差异,以形成具有小于约80°的前进接触角的眼科装置; 使眼科装置与水溶液接触,该水溶液能够改变Hansen溶解度参数,质子化或可质子化的共稀释剂的去除,以增强水溶性并用所述水溶液除去所述稀释剂。
