About cataract surgery
Cataract surgery is an operation to remove the cloudy lens inside your eye (the cataract) and replace it with an artificial, clear lens.
During cataract surgery, your surgeon will make tiny cuts on the surface of your eye so they can remove the cloudy lens and replace it with a new one.
Most surgeons do an operation called phacoemulsification to remove the cataract. In this operation, they use a special instrument that uses sound waves (ultrasound) to break up the cataract. They remove the broken pieces leaving the capsule that your lens sits in. Then they put the new lens in to the empty capsule. You’ll be awake during the operation, but your surgeon will give you a local anaesthetic so you won’t be able to feel any pain. The operation doesn’t take long and you should be able to go home the same day. You won’t need to have any stitches; the tiny cuts should heal on their own with time.
