Cataract surgery removes a cloudy natural lens and replaces it with a clear artificial lens. It is one of the most successful operations worldwide for restoring sharp, bright vision.
What happens during cataract surgery
The procedure is usually done as a day case with local anaesthetic drops. Most people remain awake but relaxed while the surgeon works through a small incision.
- Ultrasound or laser technology softens and removes the cloudy lens.
- A folded lens implant is inserted through the same tiny opening.
- The wound seals without stitches in most modern operations.
- Lens power is chosen to target distance, intermediate, or near focus.
- Both eyes are often treated on separate days for safety and comfort.
Recovery, benefits, and risks
Vision usually improves within days, though fine tuning continues over weeks. As with any eye surgery, there are small risks that are carefully explained beforehand.
- Temporary glare, halos, and mild dryness are common early sensations.
- Eye drops for several weeks reduce inflammation and prevent infection.
- Serious complications such as infection or retinal detachment are rare.
- Driving and work can often resume once vision meets legal standards.
- Regular follow up ensures the lens is stable and checks for later capsule clouding.
