Neuroadaptation is the process by which the brain learns to interpret and adjust to new visual information. When vision changes or difficulties arise in processing certain stimuli—as happens after cataract surgery with implantation of presbyopia-correcting intraocular lenses (IOLs)—the brain needs time to reorganize and optimize how it processes those images. During the first few weeks after surgery, this process demands greater cerebral effort related to attention, visual interpretation and learning new processing strategies. Over time, thanks to brain plasticity, vision becomes more natural and automatic, reducing the effort needed for everyday tasks such as reading, focusing or perceiving details and contrasts.
