Abstract
An intraocular lens adapted for deployment within a lens capsule. At least part of a lens surface of the intraocular lens constitutes a cell inducing region in which are directly formed a multitude of microgrooves. The microgrooves 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. The minute linear grooves and lands are formed with a chained pattern connected in the circumferential direction of the lens surface 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 and impart visible light transmittance of 60% or above to the cell inducing region.
