Abstract
An intraocular lens of the present invention has a substantially circular or elliptical optical lens portion made of a soft material, and an arm-shaped support arm portion attached to outer peripheral edges of this optical lens portion, and out of the peripheral edges of the optical lens portion that are contiguous to both sides in a width direction of a root of the support arm portion, at least one outer peripheral edge has a portion recessed inward from the convex curve. Thus, there is provided a soft intraocular lens that can be inserted into an eye from a further smaller incision, without damaging an optical function as much as possible.
Claims5
A soft intraocular lens, comprising:
- an optical lens portion having a substantially circular or elliptical optical lens portion made of a foldable soft material;
- and
- a support arm portion formed into an arm shape, extending outward from outer peripheral edges of this optical lens portion, for retaining/fixing the optical lens portion in an eye,
- wherein a major part of an outer circumference contour lines of the optical lens portion is formed so as to be placed on a continuous convex curve, and out of the peripheral edges of the optical lens portion that are contiguous to both sides in a width direction of the root of the support arm portion, at least one outer peripheral edge has a portion recessed inward from the convex curve, with one end of this recessed portion continued to the outer circumference contour lines of the optical lens placed on the convex curve, and the other end of this recessed portion continued to the contour lines of an outer edges in the width direction of the root of the support arm portion.
