发明名称 INTRAOCULAR LENS AND ITS MANUFACTURING METHOD
摘要 An intraocular lens (10) adapted for deployment within a lens capsule. At least part of a lens surface (16, 18, 30) of the intraocular lens (10) constitutes a cell inducing region (26, 32) in which are directly formed a multitude of microgrooves (28). The microgrooves (28) take a form of minute linear grooves and lands of depth dimension between 0.01 and 1.0 µm and width dimension between 0.1 and 2.0 µm extending with prescribed length in a circumferential direction on the lens surface (18, 30). The minute linear grooves and lands are formed with a chained pattern connected in the circumferential direction of the lens surface (18, 30) and with a periodic pattern arrayed periodically in a diametrical direction so that the minute linear grooves and lands are formed without intervening spaces throughout the entire cell inducing region (26, 32) and impart visible light transmittance of 60% or above to the cell inducing region (26, 32).
