# Is YAG capsulotomy suitable if colours look dull?

Duller colours after cataract surgery can result from posterior capsule opacification, and YAG capsulotomy may be suitable if this is the main cause.

## How PCO affects colour

Haze reduces brightness and contrast.

- Whites appearing grey or slightly yellowed compared with earlier
- Blues and greens looking less vivid
- Difficulty distinguishing subtle shades in clothing or artwork
- Findings of capsule thickening that scatter incoming light
- Little change in lens implant type or other eye structures

## When YAG is likely to help

Colour often brightens once the capsule is opened.

- Moderate or dense PCO clearly degrading image quality
- No major new macular disease or optic‑nerve damage
- Desire to restore colour and contrast for hobbies or work
- Willingness to accept small risks in exchange for potential improvement
- Follow‑up to check that colour and brightness have improved as expected
