Cataract surgery

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.

To start the surgery your surgeon will make microscopic 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.

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.

You should be able to go home the same day with any pain or discomfort only lasting 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.
