Detailed Description

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

Analyzing the subjective and objective visual outcomes and related factors following the implantation of various types of intraocular lenses（bifocal, trifocal, extended depth of focus (EDOF), and astigmatism-correcting intraocular lenses), exploring the advantages, disadvantages, and suitable patient populations for different types of intraocular lenses, analyzing the factors affecting postoperative visual quality, and providing guidance to better assist patients with diverse needs in clinical settings, aiming to offer multidimensional postoperative visual quality."
