obtain incision aberration information corresponding to the corneal incision information,

calculate a second wavefront aberration distribution that is a wavefront aberration distribution after formation of the incision based on the first wavefront aberration distribution and the incision aberration information, and

output guide information that guides an intraocular lens surgery based on the second wavefront aberration distribution.

2. The ophthalmic apparatus according to claim 1 , wherein

the corneal incision information includes at least either information on a corneal incision position or information on a corneal incision size.

3. The ophthalmic apparatus according to claim 2 , wherein

the controller calculates a post-incision astigmatic axial direction that is an astigmatic axial direction of the examinee's eye after the incision based on the second wavefront aberration distribution and outputs information on this post-incision astigmatic axial direction as the guide information.

4. The ophthalmic apparatus according to claim 3 , wherein

the controller generates a graphic indicating the information on the post-incision astigmatic axial direction as the guide information and superimposes and displays this graphic on the examinee's eye image.

5. The ophthalmic apparatus according to claim 1 , wherein

the controller calculates diopter power of an intraocular lens using the second wavefront aberration distribution.

6. The ophthalmic apparatus according to claim 1 , wherein

the controller calculates the second wavefront aberration distribution based on change information on two-dimensional change in wavefront aberration distribution on the eye included in the incision aberration information and the first wavefront aberration distribution.

7. The ophthalmic apparatus according to claim 6 , wherein

the change information includes high-order aberration.

8. The ophthalmic apparatus according to claim 1 , wherein

the controller calculates a pupil diameter of the examinee's eye from the examinee's eye image and calculates a wavefront aberration distribution in a cornea region corresponding to the pupil diameter as the first wavefront aberration distribution.

9. The ophthalmic apparatus according to claim 1 , wherein

the examinee's eye image is an anterior segment image, and

the controller calculates the second wavefront aberration distribution based on the first wavefront aberration distribution, the incision aberration information, and information on the anterior segment image.

10. The ophthalmic apparatus according to claim 1 , wherein

the intraocular lens is a TORIC-Intraocular lens, and

the controller further calculates a third wavefront aberration distribution that is a wavefront aberration distribution in the examinee's eye in which the TORIC-Intraocular lens has been inserted based on the second wavefront aberration distribution and an aberration distribution of the TORIC-Intraocular lens.

11. The ophthalmic apparatus according to claim 10 , wherein

the controller calculates the third wavefront aberration distribution in accordance with an angle to arrange the TORIC-Intraocular lens.

12. The ophthalmic apparatus according to claim 10 , wherein

the controller obtains a simulation image on how a predetermined target is formed on a retinal surface of the examinee's eye at the time of insertion of the TORIC-Intraocular lens in the examinee's eye based on the third wavefront aberration distribution.

13. The ophthalmic apparatus according to claim 11 , wherein

the input unit further allows input of the angle to arrange the TORIC-Intraocular lens.

14. A non-transitory recording medium having stored therein an ophthalmic program configured to make an information processing device function as the controller in the ophthalmic apparatus according to claim 1 .

15. A non-transitory recording medium having stored therein an ophthalmic program configured to make a controller configured to control operation of an ophthalmic apparatus execute:

calculation of a first wavefront aberration distribution that is a wavefront aberration distribution of a cornea before incision on an examinee's eye based on an examinee's eye image;

acquisition of incision aberration information corresponding to corneal incision information on a corneal incision to be formed on the cornea of the examinee's eye;

calculation of a second wavefront aberration distribution that is a wavefront aberration distribution after formation of the incision based on the first wavefront aberration distribution and the incision aberration information; and

output of guide information that guides an intraocular lens surgery based on the second wavefront aberration distribution.
