摘要：
A bioanalogic implantable ophthalmic lens (“BIOL”) capable of replacing the natural crystalline lens (NCL) in its various essential functions after the NCL having been removed and BIOL implanted into the posterior eye chamber and placed into the capsular bag vacated from the NCL. At least the posterior surface of the lens has a convex shape and is made from a transparent flexible hydrogel material. At least the anterior and posterior optical surfaces are defined by rotation of one or more conic sections along the main optical axis and the surfaces defined by the rotation will include a plane perpendicular to the axis and conical surface symmetrical by the axis. A hydrogel implantable ophthalmic lens whose optical parameters can be optimized and/or customized by a controlled absorption of electromagnetic radiation resulting in a change of the refractive index of the irradiated hydrogel.
