In traditional cataract surgery, the clouded natural lens is removed and replaced with a monofocal intraocular lens (IOL) that focuses light appropriately to provide clear vision. In this scenario, patients typically require glasses for near reading. However, new-generation multifocal intraocular lenses (IOLs) offer seamless focal transitions between distant, intermediate, and near distances. This enables post-surgery patients to live their lives without glasses at all distances.
