Cataract surgery

Hero-Desktop-1920

A procedure to improve vision impaired by cataracts

Cataract surgery can restore normal vision by replacing the clouded lens in your eye with an artificial one

About

A cataract is a clouding of the lens in your eye, which can make your vision blurred or misty. You can develop cataracts in one or both of your eyes. A straightforward surgical procedure can remove and replace the lens affected by cataracts.

  • What happens icon plus

    Before the procedure, your surgeon will put drops in your eye to widen your pupil and relax the muscles in your eye. Local anaesthetic drops are then applied to numb your eye and block pain during surgery.

    Your surgeon will make tiny cuts on the surface of your eye. Using a specialised instrument that emits ultrasonic waves, they will break up the lens affected by the cataract into tiny pieces and remove it. The natural lens is then replaced by an artificial one, called an intraocular lens (IOL). An IOL is a clear plastic lens that requires no care and becomes a permanent part of your eye.

    The whole procedure usually takes around 20 minutes.

  • How to prepare icon plus

    Your consultant will explain the procedure to you and answer any questions you may have.

    You might need to have an assessment before your surgery to measure your eyes. This will help your consultant to select the artificial lens that is best for you.

    Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you.

  • Afterwards icon plus

    You should be able to go home and get back to your usual routine straight away. Any pain or discomfort should only last for a day or two. Your consultant may give you some eye drops to reduce any swelling or inflammation in your eye.

    Most people who have cataract surgery find that their sight has improved immediately. However, your vision may still be blurred until your eye has fully healed. This can take from two to six weeks. You may need to wear reading glasses after cataract surgery.
