# What is a cataract extraction?

A cataract extraction is the surgical removal of a cloudy natural lens from the eye. Modern procedures almost always include implantation of a clear artificial intraocular lens at the same time.

## Modern Phacoemulsification

The most common technique used in [cataract surgery](https://bluefinvision.com/cataract-surgery/) is phacoemulsification. Ultrasound energy breaks the lens into small fragments, which are then aspirated through a tiny incision.

- The incision is usually self-sealing without stitches
- A foldable lens implant is inserted through the same opening
- The operation is typically performed under local anaesthetic

## Older Techniques

Extra-capsular extraction and, more rarely, intra-capsular extraction are older methods now reserved for specific situations. They require larger incisions and different approaches to lens removal.
