Intraocular lens that matches an image surface to a retinal shape, and method of designing same

1. A method of matching an image surface to a retina surface, comprising:

receiving a measurement of at least a shape of a retina of a subject eye;

determining a lens power that would focus light passing through the cornea and the pupil of the subject eye onto the retina surface;

determining a shape of an image surface that would be produced by the eye with an IOL having the lens power;

comparing the image surface shape to the shape of the retina surface;

selecting a base lens power, including:

in the case the image surface is flatter than the retina surface, selecting a base lens power greater than the lens power;

in the case the image surface is less flat than the retina surface, selecting a base lens power less than the lens power;

calculating a complimentary lens power equal to the lens power minus the selected base lens power; and

providing for insertion in the subject eye's line of sight a base lens having the base lens power and a complementary lens having the complementary lens power.

2. The method of claim 1 , wherein the base lens and the complementary lens are provided for insertion individually.

3. The method of claim 1 , further comprising assembling a compound IOL that includes the base lens and the complementary lens, whereby the insertion of the base lens and the complementary lens is achieved by implanting the compound IOL.

4. The method of claim 3 , wherein the compound IOL is assembled using components selected from a plurality of preformed base lenses and a plurality of preformed complementary lenses.

5. The method of claim 3 , wherein the compound IOL is selected from a plurality of pre-formed compound IOLs.

6. The method of claim 1 , further comprising selecting at least one additional optical element for the compound IOL to correct image aberration.

7. The method of claim 6 , wherein the additional optical element is an aperture.

8. The method of claim 1 , wherein the providing for insertion includes providing for a surgical modification of the cornea of the eye.

9. A system for specifying a plurality of intraoptical lenses that combine to form an image shape matched to a retina surface, comprising:

biometric apparatus operable to measure the dimensions and retina shape of an eye and to produce measurement data thereof;

a computing processor operable to receive the measurement data from the biometric apparatus; and

a non-transitory data storage device in data communication with the processor and storing therein information of a plurality of IOL lenses and instructions which, when executed on the processor, cause the system to:

determine a lens power of a default IOL that would focus light passing through the cornea and the pupil of the eye onto the retina according to the measurement data;

determine a shape of an image surface that would be produced by the eye with the default IOL;

compare the image surface shape to the shape of the retina;

select a base lens power, including:

in the case the image surface is flatter than the retina surface, selecting a base lens power greater than the default IOL lens power; and

in the case the image surface is less flat than the retina surface, selecting a base lens power less than the default IOL lens power;

calculating a complimentary lens power equal to the default lens power minus the selected base lens power; and

specifying a base lens having the base lens power and a complementary lens having the complementary lens power for implantation in the eye.
