Outcome Measures

Primary Outcomes (3)

Capsular bend index
The average value of the capsular bag bending stage in different positions of IOL represents the speed of the whole capsular bag bending formation in the eye.
1-2 hours after operation, 1 day, 1 week, 1 month and 3 months.
IOL rotation degree
The difference of degrees between the actually measured Toric IOL astigmatism axes at two adjacent follow-up time points.
1-2 hours after operation, 1 day, 1 week, 1 month and 3 months.
Toric IOL total axial deviation
The degree difference between the actual axial position and the target axial position of Toric IOL is different.
1-2 hours after operation, 1 day, 1 week, 1 month and 3 months.

Study Arms (2)

Not ApplicableEnrolling By Invitation

After operation, the anterior capsule completely covered the edge of intraocular lens optical surface.

Able to understand, cooperate and complete all follow-up.

You may not qualify if:

Moderate and severe dry eye
There is irregular corneal astigmatism.
Combined with other ophthalmic diseases Previous history of ophthalmic surgery.
The capsulorhexis is too large or eccentric, which can not cover the optical zone of intraocular lens all around, and there are intraoperative or postoperative complications.
