Claim 10
Dependent Claim
67 words
The intraocular lens of claim 1 which further includes a plurality of appendages associated with said optical portion, each appendage including at least a first portion and a connected second portion and means for permitting rotation of said first portion of said at least one appendage in relation to said optical portion upon the application of an actuating force upon said second portion of said each appendage.
Claim 11
Dependent Claim
47 words
The intraocular lens of claim 9 in which said means for permitting rotation of said first portion of each of said plurality of appendages includes an enclosure connected to said optical portion, said first portion of each plurality of appendages being rotatable within each of said enclosures.
Claim 12
Dependent Claim
29 words
The intraocular lens of claim 10 which additionally comprises means for confining at least a part of said portion of each of said plurality of appendages to said enclosure.
Claim 13
Dependent Claim
46 words
The intraocular lens of claim 11 in which said means for confining at least a part of said first portion of each of said plurality of appendages to each of said enclosures includes an enlargement on said first portion of each of said plurality of appendages.
Claim 14
Dependent Claim
53 words
