About this trial
This longitudinal observational study aims to evaluate long-term visual adaptation trajectories, optical quality, and patient-reported outcomes in age-related cataract patients following bilateral implantation of multifocal or mix-and-match intraocular lenses (IOLs). Patients will be followed up longitudinally after surgery to systematically assess visual performance and quality of life.
Eligibility criteria
Qualifiers
Age 18 years or older with age-related cataract requiring bilateral phacoemulsification and intraocular lens (IOL) implantation
Corneal astigmatism less than 0.75 D
Good general health and willing to complete all postoperative follow-up visits
Signed written informed consent
Disqualifiers
Previous ocular surgery or ocular trauma
Coexisting ocular diseases affecting visual potential, such as corneal opacity, glaucoma, macular degeneration, or diabetic retinopathy
Intraoperative or postoperative complications (e.g., posterior capsule rupture)
Systemic diseases that may interfere with visual outcomes or follow-up compliance
