Cataract surgery

Surgery is the only treatment that removes a cataract. It is one of the most common and successful operations in the NHS.

When surgery is offered

In the early stages, stronger glasses and brighter lighting may be enough. NICE says surgery should be offered when a cataract is affecting your daily life, not based on how cloudy it is.

What happens

  • it is usually done as a day case under local anaesthetic, so you are awake but cannot feel it
  • the surgeon removes the cloudy lens and replaces it with a clear, artificial lens
  • it usually takes about 15 to 30 minutes
  • if both eyes need surgery, they are usually done on different days

Recovery

  • you will use eye drops for a few weeks
  • avoid rubbing your eye, swimming and heavy lifting for a short time
  • most people notice better sight within a few days

Possible problems

Complications are uncommon. Contact the eye clinic urgently if your sight gets worse, or your eye becomes very red or painful, after surgery.

Months or years later, the capsule behind the lens can become cloudy (posterior capsule opacification). This is treated with a quick, painless laser.

Common questions

Will I still need glasses after cataract surgery?

Many people see well for distance without glasses afterwards, but most still need glasses for reading. You should wait until your eye has healed, usually about 4 to 6 weeks, before getting new glasses.
