Method of making intraocular lenses |
摘要 |
Optical sections (lenses) of pseudophakoi having tangential holes are produced without drilling operations. A preform of lens material is drawn with embedded acid soluble rods and/or openings corresponding in diametral size and relative juxtaposition to the size, shape and locations of holes needed in a lens, a lens blank is cut from the drawn preform and portions of rods remaining therein are etched away prior to or following final edging and surface finishing of the lens blank.
