Abstract
An intraocularlens of novel structure by which the outer circumferential part of an optical portion can be pressed stably against a posterior capsule under worn state and crisis of secondary cataract can be suppressed more advantageously. A pair of coupling portions () are formed to hold an optical portion () between them in one direction perpendicular to the optical axis, wherein the outer fringe parts of the coupling portions () are made thicker than the outer fringe part of the optical portion (), a pair of supporting portions () are formed to project from the outer fringe parts of the coupling portions () and a edge contour part () is formed continuously on the outer fringe parts of the optical portion () and respective posterior surfaces () of the coupling portions () so as to extend smoothly along the entire circumference thereof.
