China68 participantsStarted 2024-10-01

Plain-language summary

(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.

Inclusion criteria

✓.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).
✓.After operation, the anterior capsule completely covered the edge of intraocular lens optical surface.
✓.Able to understand, cooperate and complete all follow-up.

Exclusion criteria

✕. 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.
