Why is cataract surgery performed?
A cataract is an eye condition where the lens of your eye becomes cloudy, making it difficult to see. A small operation can replace your cloudy lens with a clear plastic lens.
Cataracts can make your vision become blurry or hazy. They can also make you sensitive to bright lights, see starbursts around lights, or see everything as slightly faded or yellow. The treatment for cataracts is surgery on the affected eye to remove the cloudy lens and replace it with a permanently implanted plastic lens called an intraocular lens.
How to prepare for cataract surgery
On the day of the surgery, you will be given eye drops that include an antibiotic. You will have a small plastic tube inserted into a vein in your arm. You might be given an injection around the eye or eye drops to make the eye go numb. Most people have a local anaesthetic and light sedation, although some have a general anaesthetic.
Your doctor can give you more information to help you prepare for the operation.
What happens during cataract surgery?
During the procedure you will be asked to lie on your back for up to 45 minutes. The doctor will make a small cut in the eye to remove the cloudy lens and to insert the plastic lens. There will always be medical staff to talk to during the procedure. If you have any problems, you should tell one of the staff.
What to expect after cataract surgery
Your doctor will probably place a pad over the eye that was operated on. You might have some pain or discomfort in that eye. If you do, you should tell a nurse or doctor so they can give you something to ease the pain. You will be given eye drops and told how long you need to take them for.
Cataract surgery is an outpatient procedure and does not require an overnight stay. You should not drive until your vision has returned to normal so you will need someone to take you home.
For a few weeks after the operation, you will need to avoid rubbing your eye and strenuous activity.
What can go wrong with cataract surgery?
Problems with cataract surgery are not common but some people have bleeding, infection or damage to the eye. If you notice your eye becoming red and painful, fluid coming from the eye, or your sight getting worse, contact your eye specialist or go to an emergency department.
