Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| IOL decentration at three years | three years | Decentration was defned as the distance between the center of the toric IOL and the visual axis and was calculated using Adobe Photoshop software on the retro image exported from the OPD-scan aberrometer. |
| IOL rotation degree at six months | six months | After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis. |
| IOL rotation degree at one year | one year | After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis. |
| IOL rotation degree at three years | three years | After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis. |
| IOL tilt at one week | one week | The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer. |
| IOL tilt at two weeks | two weeks | The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer. |
| IOL tilt at one month | one month | The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer. |
| IOL tilt at three months | three months | The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer. |
| IOL tilt at six months | six months | The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer. |
| IOL tilt at one year | one year | The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer. |

| IOL rotation degree at one day | one day | After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis. |
| IOL rotation degree at three days | three days | After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis. |
| IOL rotation degree at two weeks | two weeks | After the pupil was dilated, the IOL axis was recorded using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis. |
