Intraocular lens shape factors for achieving optimum axial image quality (least spherical aberration) and zero primary oblique astigmatism for the two example eyes described in the text using both single and double lens implants
| Type of eye | Number of implants | Optimum lens shapes | ||||
|---|---|---|---|---|---|---|
| Spherical aberration | Astigmatism | |||||
| B1 | B2 | B1 | B2 | |||

| Hypermetropic eye 1 | 2 IOLs | 0.946 | 1.262 | −2.364 | −1.964 | |
| Nanophthalmic eye 2 | Single IOL | 0.553 | — | −1.438 | — | |
| Nanophthalmic eye 2 | 2 IOLs | 0.949 | 1.264 | −2.893 | −2.494 | |
