Brief Summary:
This study aims to investigate the impact of improved capsular polishing on the long-term stability of effective lens position (ELP) and visual quality in patients following femtosecond laser-assisted cataract surgery combined with intraocular lens implantation. Throughout the follow-up period, changes in ELP were observed using OCT to measure the central corneal posterior surface to the IOL anterior surface. The contraction of the anterior capsule orifice was assessed through anterior segment photography, and its diameter and area were measured and analyzed using drawing software at each follow-up visit. Additionally, the investigators analyzed the correlation between the degree of anterior capsule orifice contraction and ELP, as well as examined whether ACO formed and its degree, PCO formation and its degree. Objective examination using OQAS II was conducted to measure PSF, MTF, OSI, and SR of patients; high-order aberrations including astigmatism, trifolium, and spherical aberration were measured by OPD-Scan III. Furthermore, the investigators investigated the correlation between ACO/PCO degrees and visual quality.
