Phacoemulsification with intraocular lens (IOL) implantation is the standard surgical treatment for age-related cataract, aiming to restore visual function and improve quality of life. This prospective study evaluated 80 patients who underwent cataract surgery with either monofocal (n=40) or multifocal (n=40) IOL implantation. Postoperative assessment at 1 and 3 months included uncorrected visual acuity at far, intermediate, and near distances, contrast sensitivity, visual phenomena, and patient satisfaction. Both groups achieved significant improvement in distance vision. Multifocal IOLs provided superior near and intermediate visual acuity and reduced dependence on spectacles, while monofocal IOLs showed higher contrast sensitivity and fewer visual disturbances. These findings highlight the importance of individualized IOL selection based on patient lifestyle, visual requirements, and tolerance for optical side effects to optimize functional outcomes and satisfaction after cataract surgery.
