IOL rotation degree at one hour
After the pupil was dilated, the IOL axis was recorded by a senior surgeon (C. L.) using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
Time frame: one hour
IOL rotation degree at 1 day
After the pupil was dilated, the IOL axis was recorded by a senior surgeon (C. L.) using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
Time frame: one day
IOL rotation degree at 3 days
After the pupil was dilated, the IOL axis was recorded by a senior surgeon (C. L.) using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
Time frame: three days
IOL rotation degree at 1 week
After the pupil was dilated, the IOL axis was recorded by a senior surgeon (C. L.) using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
Time frame: one week
IOL rotation degree at 2 weeks
After the pupil was dilated, the IOL axis was recorded by a senior surgeon (C. L.) using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
Time frame: two weeks
IOL rotation degree at 1 month
After the pupil was dilated, the IOL axis was recorded by a senior surgeon (C. L.) using the same slit-lamp microscope. IOL rotation was defined as the difference between the target and final axis.
