Method of making artificial intraocular lenses with holes

摘要

Making perforate optical sections (lenses) of pseudophakoi with avoidance of drilling operations and adversities thereof. Lens material is drawn with embedded acid soluble columns corresponding in diametral size and relative juxtaposition to the size and spaced locations of holes needed in a lens and the columns are etched away prior to or following final edging and surface finishing of the lens. Making multiple lens preforms is contemplated.
