Method of using a small incision lens

A method of correcting a lack of accommodation, comprising:

• making an incision having a length less than 1.5 mm for access to an eye;
• providing an intraocular lens, wherein the intraocular lens comprises an optical portion having a first optical surface, wherein the first optical surface is constructed of a material which is biologically compatible with a tissue of an eye, the optical portion having a predetermined maximum thickness under which the material may be rolled without exceeding the elastic limit of the material, said optical portion having a predetermined minimum thickness above which the material retains a normal shape, wherein the intraocular lens is capable of deforming for passage through an incision having a length smaller than about 1.5 millimeters so that the intraocular lens is placed into the eye;
• the optical portion having a second optical surface, wherein the second optical surface comprises a central disk which is radially surrounded by a series of annular rings, the central disk and the series of annular rings forming a series of radial steps along the second optical surface so that a focal length from an annular ring is adjusted to focus at a same point as a prime meridian of the lens, each annular ring having an outer surface, wherein the second optical surface and the first optical surface have a minimum separation of 0.025 mm and a maximum separation of 0.065 mm;
• and an anchoring portion having a maximum thickness of 100 microns attached to the optical portion, wherein the anchoring portion is constructed of a material which is biologically compatible with a tissue of an eye, wherein the anchoring portion is capable of biasing against a support structure of the eye;
• warming an intraocular lens to a temperature from about 90 degrees F. to about 150 degrees F.;
• rolling the intraocular lens around a rod;
• inserting the intraocular lens through the incision;
• and
• anchoring the intraocular lens to the support structure of the eye.

A method of treating presbyopia, comprising:

• providing an intraocular lens, wherein the intraocular lens comprises an optical portion having a first optical surface, wherein the optical portion is constructed of a material which is biologically compatible with a tissue of an eye, the optical portion having a predetermined maximum thickness under which the material may be rolled without exceeding the elastic limit of the material, said optical portion having a predetermined minimum thickness above which the material retains a normal shape, wherein the intraocular lens is capable of deforming for passage through an incision having a length smaller than about 1.5 millimeters so that the intraocular lens is placed into the eye;
• the optical portion having a second optical surface, wherein the second optical surface comprises a central disk which is radially surrounded by a series of annular rings, the central disk and the series of annular rings forming a series of radial steps along the second optical surface so that a focal length from an annular ring is adjusted to focus at a same point as a prime meridian of the lens, wherein the second optical surface and the first optical surface have a minimum separation of 0.025 mm and a maximum separation of 0.45 mm;
• and an anchoring portion attached to the optical portion, wherein the anchoring portion is constructed of a material which is biologically compatible with a tissue of an eye, wherein the anchoring portion is capable of biasing against a support structure of the eye;
• heating the intraocular lens to a temperature of about 90 degrees F. to about 150 degrees F.;
• cutting an eye so that an incision having a length of less than 1.5 mm is provided;
• deforming the intraocular lens so that the intraocular lens is capable of passing through the incision;
• reducing the temperature of the intraocular lens to about room temperature so that the intraocular lens hardens;
• inserting the intraocular lens into the incision;
• and
• positioning the intraocular lens so that the anchoring portion biases against an anterior surface and a posterior surface of a capsular sac.
