Claim 12

A lens body in accordance with claim 5 in which said magnet means are formed of Samarium Cobalt Alloy.

Claim 13

A lens body in accordance with claim 10 comprising position fixation means for supporting said lens body within the eye.

Claim 14

An intralocular lens according to claim 1, wherein said central portion is adapted to focus rays of light and each of said side portions is substantially opaque to light.

Claim 15

An intraocular lens according to claim 3, wherein said central optic portion is substantially rigid and has a maximum dimension, transverse to the direction of its insertion into an eye, which is substantially less than 5 mm in length so that said central optic portion can be inserted through an opening in the cornea which is substantially less than 5 mm in length.

Claim 16

An intraocular lens according to claim 13, wherein said outer portions are each substantially rigid and each has a maximum dimension, transverse to the direction of its insertion into an eye, which is substantially less than 5 mm in length so that said outer portions can each be inserted through an opening in the cornea which is substantially less than 5 mm in length.

Claim 17

An intraocular lens according to claim 3, wherein said central optic portion and said outer portions are all made of the same material, said central portion having an optical finish and said outer portions having a rough unground surface resulting in their being opaque.

Claim 18

An intraocular lens according to claim 3, wherein each said magnet members is rod-shaped, and have a length of about 1 mm and a diameter of about 1/2 mm.

Claim 19

An intraocular lens according to claim 16, wherein said magnet members are formed of Samarium Cobalt Alloy.

Claim 20

An intraocular lens according to claim 1, wherein said central optic portion has a generally rectangular configuration.

Claim 21

An intraocular lens according to claim 18, further comprising locating means on said central portion and on each said outer portions for locating the latter with respect to said central portion for facilitating assembly thereof within the eye.

Claim 22

An intraocular lens according to claim 19, wherein said locating means comprises a projection on one of said lens portions and a corresponding aperture on the adjacent one of said lens portion.

Claim 23

An intraocular lens according to claim 16, wherein at least one of said magnet members protrudes outwardly from an edge of one of said portions and the adjacent edge of the abutting one of said portions comprises an aperture for receiving said protruding magnet member for locating the portions in question with respect to each other.

Claim 24

An intraocular lens according to claim 18, wherein said central optic portion has a height to width relation of about 2:1.

Claim 25

An intraocular lens comprising: a lens body having a miniature central lightfocusing optic portion and a pair of separate substantially opaque outer portions adapted to be located adjacent to opposite peripheral regions of said central optic portion; first magnet means at said opposite peripheral regions of said miniature central optic portion; second magnet means on each said outer portions of said lens body for cooperating with said first magnet means on said central optic portion for detachably connecting said outer portions with said central optic portion, whereby said central optic portion and said opaque outer portions can each be independently inserted into the eye, through a smaller opening in the eye than the opening through which said lens body could be inserted after it is assembled; and position-fixation means cooperating with at least one of said portions for fixing the position of said lens body within the eye.
