Condition: Lens Diseases · Sponsor: Second Affiliated Hospital, School of Medicine, Zhejiang University
The goal of cataract surgery has evolved from simply restoring sight to providing clear and comfortable full-range vision. Traditionally, monofocal IOLs remain the routine choice for special cases with anterior segment abnormalities-such as lens subluxation, cataract with chronic uveitis, post-laser refractive cataract, and aphakia with insufficient capsular support. However, there is a growing demand among these patients for improved visual quality and spectacle independence.Currently, various presbyopia-correcting IOLs offer distinct advantages, providing more personalized options. The introduction and application of intraoperative optical coherence tomography (iOCT) ensures effective intraoperative monitoring. These advances make the precise implantation of presbyopia-correcting IOLs a promising extension to phacoemulsification in complex cataracts with anterior segment abnormalities. Nevertheless, their exact benefits regarding visual quality, safety, and patient satisfaction require systematic evaluation through rigorous prospective studies and long-term follow-up. Under strict perioperative management, this study will employ iOCT to monitor the accurate implantation of presbyopia-correcting IOLs and will assess postoperative visual quality and patient satisfaction.
