Short answer
Have cataract surgery when vision affects daily life — driving, reading, work, or disabling glare — or earlier if you want a premium trifocal or EDOF IOL while biometry is still optimal. You do not have to wait until vision is severely impaired or you fail a standard sight test.
Signs it is time for surgery
- 1New glasses no longer help — clouding is inside the lens, not correctable by updating your prescription alone.
- 2Night driving glare — headlights and streetlights cause disabling halos before distance acuity fails a chart test.
- 3Colours faded or yellowed — whites look cream; blues look dull.
- 4Optician confirmed cataract — and functional impact is increasing.
Can I have surgery before the cataract is "ripe"?
Yes — modern phaco works at earlier stages. The old "wait until mature" advice is outdated. Many patients choose surgery earlier for premium IOL biometry and quality-of-life reasons.
Very dense cataracts can make biometry less predictable — another reason some patients plan surgery before clouding advances. Compare: Cataract surgery vs RLE.
When to wait
- Early clouding with minimal daily impact
- Uncontrolled glaucoma — optimise first
- Active retinal disease needing treatment first
- Driving, reading, or work affected
- Glare is disabling — especially at night
- You want trifocal/EDOF IOL before lens becomes very dense
- Both eyes planned — bilateral trip arranged
