简要总结
This is a prospective, multi-center, randomized comparative study. The purpose of the study is to evaluate and compare the objective and subjective visual outcomes of different types of functional intraocular lenses (IOLs) in patients.
详细描述
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."
