CLAIMS

1. An apparatus for intraocular lens selection, comprising:

a biometer configured to obtain at least two ocular measurement parameters for an eye;

a user interface configured to obtain a lens selection parameter for the eye; an autorefractor configured to obtain a post-operative refraction of the eye; a memory; and

a processor communicatively coupled to the biometer, the user interface, the autorefractor, and the memory, and configured to:

determine an intraocular lens power based on a formula using the at least two ocular measurement parameters; and

correlate the at least two ocular measurement parameters, the intraocular lens power, and the post-operative refraction as a training set.

2. The apparatus of claim 1 , wherein the processor is configured to train a deep learning machine using the post-operative refraction of the eye and the intraocular lens power to determine an estimated error of the formula.

3. The apparatus of claim 1 , wherein the processor is configured to

determine the estimated error of the formula using a deep learning machine trained on verified post-operative results including post-operative refractions corresponding to intraocular lens powers;

adjust the lens selection parameter based on the estimated error; and redetermine a final intraocular lens power based on the formula and the adjusted lens selection parameter.

4. The apparatus of claim 1 , wherein the processor is configured to include the final intraocular lens power in the training set.

5. The apparatus of claim 1 , wherein the lens selection parameter is one of a target refraction or A-constant.

6. The apparatus of claim 1 , wherein the at least two ocular measurement parameters are selected from the group consisting of: axial length, corneal power, corneal power index, and anterior chamber depth.

7. The apparatus of claim 1 , wherein the lens selection formula includes one or more of: a Hoffer Q formula, a Holladay I formula, a Haigis formula, and a SRK/T formula, a Barrett Universal II formula, or adjustments thereto.

8. The apparatus of claim 1 , wherein the ocular measurement parameters include intraoperative aberrometry measurements.

9. The apparatus of claim 1 , further comprising:

a display device, wherein the processor is configured to render the intraocular lens power on a relevant portion of a super surface including ideal or near ideal portions of a plurality of intraocular lens selection formulas based on a range of the at least two ocular measurement parameters most suitable to each individual intraocular lens selection formula.

10. A method of intraocular lens selection, comprising:

obtaining at least two ocular measurement parameters for an eye by a biometer;

obtaining a lens selection parameter for the eye;

determining an intraocular lens power based on a formula using the at least two ocular measurement parameters;

obtaining a post-operative refraction of the eye from an autorefractor communicatively coupled with the biometer; and

correlating the at least two ocular measurement parameters, the intraocular lens power, and the post-operative refraction as a training set.

11. The method of claim 10, further comprising training a deep learning machine using the post-operative refraction of the eye and the intraocular lens power to determine an estimated error of the formula.

12. The method of claim 10, further comprising:

determining the estimated error of the formula using a deep learning machine trained on verified post-operative results including post-operative refractions corresponding to intraocular lens powers;

adjusting the lens selection parameter based on the estimated error; and

redetermining a final intraocular lens power based on the formula and the adjusted lens selection parameter.

13. The method of claim 12, wherein correlating the at least two ocular measurement parameters, the intraocular lens power, and the post-operative refraction as a training set comprises including the final intraocular lens power in the training set.

14. The method of claim 10, wherein the lens selection parameter is one of a target refraction or A-constant.

15. The method of claim 10, wherein the at least two ocular measurement parameters are selected from the group consisting of: axial length, corneal power, corneal power index, and anterior chamber depth.

16. The method of claim 10, wherein the lens selection formula includes one or more of: a Hoffer Q formula, a Holladay I formula, a Haigis formula, and a SRK/T formula, a Barrett Universal II formula, or adjustments thereto.

17. The method of claim 10, wherein the ocular measurement parameters include intraoperative aberrometry measurements.

18. A non-transitory computer-readable medium storing computer executable instructions, comprising instructions to cause a computer to:

obtain at least two ocular measurement parameters for an eye by a biometer;

obtain a lens selection parameter for the eye;

determine an intraocular lens power based on a formula using the at least two ocular measurement parameters;

obtain a post-operative refraction of the eye from an autorefractor

communicatively coupled with the biometer; and

correlate the at least two ocular measurement parameters, the intraocular lens power, and the post-operative refraction as a training set.

19. The non-transitory computer-readable medium of claim 18, further comprising instructions to cause the computer to train a deep learning machine using the post operative refraction of the eye and the intraocular lens power to determine an estimated error of the formula.

20. The non-transitory computer-readable medium of claim 18, further comprising instructions to cause the computer to:

determine the estimated error of the formula using a deep learning machine trained on verified post-operative results including post-operative refractions corresponding to intraocular lens powers;

adjust the lens selection parameter based on the estimated error; and redetermine a final intraocular lens power based on the formula and the adjusted lens selection parameter.
