Thin intraocular lens

An intraocular lens for implantation in an eye comprising:

• a resiliently deformable silicone based optic having a maximum cross sectional area of no greater than about 4.4 square millimeters and an index of refraction of at least about 1.445, said optic being configured so that the optic can be resiliently deformed from a normal optical condition into a deformed insertion condition to permit the intraocular lens to be passed through a scheral tunnel incision of no longer than about 3.2 millimeters into the eye;
• fixation means coupled to the optic for retaining the optic in the eye;
• and
• said optic when implanted in the eye being in the normal optical condition and having sufficient rigidity to be substantially free of optical distortion resulting from force from the eye acting on the intraocular lens and said optic when implanted in the eye being of sufficient size to substantially prevent glare resulting from interaction of light and the periphery of the optic.

An intraocular lens for implantation in an eye comprising:

• a generally circular resilient, deformable silicone based optic having a maximum cross sectional area of no greater than about 4.4 square millimeters, an index of refraction of at least about 1.445, a diopter power in the range of from about 12d to about 24d and a diameter of at least about 5 millimeters;
• said optic having anterior and posterior faces, at least one of said faces being convex;
• and
• fixation means for retaining the optic in the eye.

An intraocular lens for implantation in an eye comprising:

• a generally circular resilient, deformable optic having an elongation of at least about 200 percent, a maximum cross sectional area of no greater than about 4.4 square millimeters, an index of refraction of at least about 1.445, a diopter power in the range of from about 12d to about 24d and a diameter of at least about 5 millimeters;
• said optic having anterior and posterior faces, at least one of said faces being convex;
• and
• fixation means for retaining the optic in the eye.

A set of intraocular lenses for implantation in eyes, said set of intraocular lens comprising:

• first, second, third and fourth intraocular lenses;
• each of said first, second, third and fourth intraocular lenses including a resilient, deformable silicone based optic configured so that the optic can be deformed to permit the intraocular lens to be passed through a scleral tunnel incision of no longer than about 3.2 millimeters into the eye and fixation means for retaining the optic in the eye, each of said optics having a periphery and when implanted in the eye having sufficient rigidity to be substantially free of optical distortion resulting from force from the eye acting on the intraocular lens and each of said optics when implanted being of sufficient size to substantially prevent glare resulting from interaction of light on the periphery of the optic;
• and
• said optics of said first, second, third and fourth intraocular lenses having diopter powers in the ranges of from about 12d to about 14.5d from about 15d to about 18.5d from about 19d to about 21.5d and from about 22d to about 24d respectively.

An intraocular lens for implantation in an eye comprising:

• a resiliently deformable silicone based optic having a maximum cross sectional area of no greater than about 4.4 square millimeters and an elongation of at least about 260 percent, said optic being configured so that the optic can be resiliently deformed from a normal optical condition into a deformed insertion condition to permit the intraocular lens to be passed through a scleral tunnel incision of no longer than about 3.2 millimeters into the eye;
• fixation means coupled to the optic for retaining the optic in the eye;
• and
• said optic when implanted in the eye being in the normal optical condition and having sufficient rigidity to be substantially free of optical distortion resulting from force from the eye acting on the intraocular lens and said optic when implanted in the eye being of sufficient size to substantially prevent glare resulting from interaction of light and the periphery of the optic.
