In this video Dr O'Donovan explains key things you need to know about cataract eye surgery.

Cataract surgery is a procedure where a cloudy lens in the eye is replaced with a clear artificial lens (IOL) to improve vision. It's a common and generally safe operation, often done when cataracts affect daily life or vision.

What are cataracts? Cataracts are a clouding of the lens in the eye, which can cause blurry or hazy vision, sensitivity to light, and difficulty seeing at night.

Why is cataract surgery needed? Cataracts can significantly impact vision, making everyday activities like reading, driving, and recognizing faces difficult. Surgery is the only way to remove cataracts and restore clear vision.
How is cataract surgery performed?

1. Phacoemulsification: This is the most common technique. It involves using ultrasound waves to break up the cloudy lens into small pieces, which are then suctioned out.
2. Extracapsular surgery: A larger incision is made to remove the lens, and the artificial lens is inserted through the same opening.
Lens replacement: After removing the natural lens, a clear artificial lens (IOL) is implanted to restore focus.

Types of IOLs: Monofocal: Corrects vision at a single distance (near or far).

Multifocal or Toric: May correct vision at multiple distances or astigmatism.

Accommodating: Can adjust focus for different distances.

What to expect during and after cataract surgery:

Local anesthesia: The eye is numbed, and you may be given a sedative to help you relax.
Outpatient procedure: You can usually go home the same day.
Recovery: Most people recover within a few weeks, with some experiencing improved vision within days.
Post-operative care: Eye drops and follow-up appointments are usually needed.
