Claims8
An intraocular lens (IOL), comprising:
- an optic portion having a circular shape and including a first pattern which includes a plurality of ridges and a plurality of grooves;
- and
- a plurality of haptic portions extending from an outer circumferential edge of the optic portion and each including a second pattern which includes a plurality of ridges and a plurality of grooves,
- wherein at least one of the ridges included in the first pattern and the second pattern and at least one of the grooves included in the first pattern and the second pattern includes a section in which a width is formed differently,
- wherein the widths of the grooves of the second pattern in a haptic portion of the plurality of haptic portions is wider than the widths of the grooves of the first pattern in the optic portion,
- wherein a groove of at least one of the first and second patterns includes a rugged part of nanometer units formed on a bottom surface thereof and a plurality of nano-sized projections formed on a side surface thereof,
- wherein the first pattern is formed over the haptic portions and the optic portion, and the second pattern is formed only on the haptic portions.
