Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

(1) To compare the difference of rotational stability and CBI between AcrySof IQ(SN6AT) and TECNIS(ZCU) after cataract surgery. (2) To evaluate the influence of capsular bending on the rotational stability of these two kinds of intraocular lenses.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To compare the difference of rotational stability and CBI between AcrySof IQ(SN6AT) and TECNIS (ZCU) torus intraocular lenses implanted after cataract surgery, and analyze the influence of capsular bag bending on the rotational stability of two kinds of astigmatism correction intraocular lenses after cataract surgery.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

3.Pupil diameter \> 7 mm after mydriasis. 4.The astigmatism meridian between IOLMaster and Pentacam is the same (the meridian difference between the two instruments is within 15).
