Surface treatments for accommodating intraocular lenses and associated methods and devices

Принадлежит: Shifamed Holdings LLC

An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid chamber. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. A surface treatment or coating may be applied to one or more surfaces of the first and second components. The surface treatment is expected to decrease the roughness of the machined surfaces of the boundary surfaces of the first and second components, and thereby reduce the mass of water coalescing at such boundary surfaces. The disclosed surface treatments are also expected to increase the hydrophobicity (i.e., decrease the surface energy) of the corresponding surface(s), thereby decreasing the “wettability” of these surfaces.
