| Intraoperative aberrometry-guided IOL rotation | |||
|---|---|---|---|
| Outcome | ≤ 5 degrees (n = 27) | > 5 degrees (n = 7) | P value |
| BSCDVA | 0.078 ± 0.020 | 0.081 ± 0.023 | P = .95 |
| UCDVA | 0.17 ± 0.025 | 0.21 ± 0.047 | P = .48 |

| UCIVA | 0.27 ± 0.041 | 0.28 ± 0.125 | P = .89 |
| Absolute residual astigmatism prediction error ≤ 0.5 D, n (%) | 26 (96%) | 6 (86%) | P = .28a |
| Residual refractive astigmatism (D) | 0.20 ± 0.055 | 0.25 ± 0.094 | P = .70 |
| Absolute postoperative IOL rotation (degrees) | 0.96 ± 0.23 | 1.57 ± 0.57 | P = .26 |
Eyes were grouped based on whether the axis of the IOL was adjusted intraoperatively by 5 degrees or more as a result of intraoperative aberrometry guidance. Visual acuity is reported as logMAR ± SEM. P values were calculated using a t test for equal means, except as follows. a, P value was calculated using a two-proportion z test for equal means
BSCDVA, best spectacle-corrected distance visual acuity; UCDVA, uncorrected distance visual acuity; DSCIVA, best distance spectacle-corrected intermediate visual acuity; UCIVA, uncorrected intermediate visual acuity
