WHAT IS CLAIMED IS:

1. An intraocular lens for implantation in to the eye of a patient, the intraocular lens comprising:

a multifocal optic having a spherical equivalent optical power less than or equal to 50 Diopters,

the multifocal optic comprising an optical add power customized for a patient's visual needs determined based on a position of the intraocular lens when implanted in the eye of the patient, and a parameter of the patient's eye.

2. The intraocular lens of claim 1, wherein the position of the intraocular lens when implanted in the eye of the patient is the effective lens position.

3. The intraocular lens of claim 1, wherein the position of the intraocular lens when implanted in the eye of the patient is the actual lens position.

4. The intraocular lens of claim 1, wherein the parameter of the patient's eye is at least one of: a corneal power, an axial length or an anterior chamber depth.

5. The intraocular lens of claim 1, wherein the optical add power is further determined based on a preferred reading distance.

6. The intraocular lens of claim 1, wherein the optical add power for a multifocal lens optimized for viewing objects at a maximum distance of 50 cm and having a spherical equivalent optical power less than or equal to 10 Diopters is between about 2.7 Diopter and about 3.4 Diopter, and

wherein the optical add power for a multifocal lens optimized for viewing objects at a maximum distance of 50 cm through the near vision zone and having a spherical equivalent optical power greater than 5 Diopter and less than or equal to 40 Diopters is between about 2.5 Diopter and about 3.4 Diopter.

7. The intraocular lens of claim 1, wherein the optical add power for a multifocal lens optimized for viewing objects at a maximum distance of 42 cm and having a spherical equivalent optical power less than or equal to 10 Diopters is between about 3.25 Diopter and about 4.0 Diopter, and

wherein the optical add power for a multifocal lens optimized for viewing objects at a maximum distance of 42 cm through the near vision zone and having a

spherical equivalent optical power greater than 10 Diopter and less than or equal to 50 Diopters is between about 3.0 Diopter and about 4.0 Diopter.

8. A kit comprising a plurality of intraocular lenses for implantation in to the eye of a patient, the kit comprising:

a plurality of multifocal optics having a spherical equivalent optical power less than or equal to 50 Diopters,

wherein the plurality of multifocal optics each of which comprise an optical add power that is optimized for viewing at one or more preferred near and/or intermediate distances, wherein for each preferred distance, the plurality of multifocal optics have an optical add power in a first range for spherical equivalent optical powers less than or equal to 10 Diopters and an optical add power in a second non-overlapping range for spherical equivalent optical powers greater than 10 Diopter and less than or equal to 50 Diopters.

9. The kit of claim 8, wherein the first range is between 2.75 Diopter and 4.0 Diopter.

10. The kit of claim 8, wherein the second range is between 2.25 Diopter and 2.75 Diopter.

11. The kit of claim 8, wherein the preferred distance is 50 cm or 42 cm.

12. The kit of claim 8, wherein the optical add power of the plurality of multifocal optics optimized for each preferred distance is calculated using a formula that depends on a position of the intraocular lens when implanted in the eye of the patient, a shape of the patient's eye, and the preferred reading distance.

13. A method of manufacturing an intraocular lens, the method comprising:

manufacturing an intraocular lens having a spherical equivalent power and a customized optical add power,

wherein the customized optical add power is based on at least one of an ocular biometry of an individual, a position of the intraocular lens in the eye, or a preferred reading distance, and

wherein ocular biometry comprises at least one of an axial length (AL) of the individual's eye, corneal power (K) or anterior chamber depth.

14. A method of designing and manufacturing a multifocal IOL that is customized for a particular reading distance, wherein the add power differs depending on the base power

15. A method of selecting the add power of an intraocular lens, the method comprising:

determining a customized optical add power based on at least one of an ocular biometry of an individual, a position of the intraocular lens in the eye, or a preferred reading distance, and

selecting from a range of existing IOLs an IOL that has an optical add power closest to the determined customized optical add power and a spherical equivalent power closest to a desired spherical equivalent power,

wherein ocular biometry comprises at least one of an axial length (AL) of the individual's eye, corneal power (K) or anterior chamber depth.
