| Measure | Description | Time Frame |
|---|---|---|
| Effective Lens Position | Effective lens position was measured with anterior chamber depth 1 day，1 week, 1 month as well as 3 months and 6 months postoperatively using anterior segment Optical Coherence Tomograph. The anterior chamber depth defined as the distance between the posterior surface of the corneal and anterior surface of intraocular lens in the pupil center along the optical axis. The actual movement of intraocular lenses was defined as the root mean square of changes in the effective lens position at each visit. | 1 day，1 week, 1 month，3 months and 6 months postoperatively |
| Measure | Description | Time Frame |
|---|---|---|
| Uncorrected Visual Acuity(UCVA) | The UCVA was recorded in logMAR units at each vist | 1 day，1 week, 1 month as well as 3 months and 6 months postoperatively |
| Refractive Error | auto refraction was performed at each visit. Spherical equivalent refraction (SER) (sphere +cylinder/2) was used in subsequent calculations. |
