结局指标
主要结局
IOL tilt at six months
时间窗: six months
The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer.
IOL tilt at one week
时间窗: one week
The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer.
IOL tilt at one year
时间窗: one year
The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer.
IOL tilt at one month
时间窗: one month
The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer.
IOL rotation degree at three months
时间窗: three 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 hour
时间窗: one hour
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 week
时间窗: one week
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 two weeks
时间窗: two weeks
The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer.
IOL tilt at three years
时间窗: three years
The tilt data were obtained from the wavefront mode of the OPD-Scan III aberrometer.
IOL decentration at six months
时间窗: six months
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 one day
时间窗: 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
