Toric Intraocular Lens (IOL) Implantation for Management of Cataracts

Study Overview
=================
Brief Summary
-----------------
This study included cataract patients who underwent toric intraocular lens (IOL) implantation, which aimed to evaluate the stability and clinical visual quality of toric IOLs.

Detailed Description
-----------------
This study included cataract patients who underwent the implantation of toric intraocular lens (IOL) with haptic design, which aimed to evaluate the stability and clinical visual quality of toric IOLs.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |

| IOL rotation degree at 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. | three days | 
| IOL rotation degree at 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. | one week | 
| IOL rotation degree at 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. | two weeks |
