Brief Summary

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

In this study, we will retrospectively collect patients who have performed phacoemulsification combined with intraocular lens implantation in our hospital, collect various preoperative biometric data and postoperative refractive data of patients, conduct statistical analysis, and compare the accuracy of various IOL calculation formulas.
