Neuroadaptation after laser eye surgery describes how the brain adjusts to new visual inputs once the optical system has been altered. This helps symptoms such as unusual clarity, altered depth perception or new visual artefacts become less noticeable over time.
Visual processing changes
After procedures that introduce multifocal optics or alter aberrations, the brain learns to prioritise useful signals and suppress less helpful ones. The duration of neuroadaptation varies, with some people adapting within weeks and others taking longer.
- Temporary awareness of halos, glare or slight imbalance between the eyes is common during this period
- Stable refraction and healthy ocular structures support successful adaptation
- Good lighting and gradual return to visually demanding tasks can help
- Persistent symptoms should be discussed at follow-up visits
