Cataract surgery is a routine operation to remove the cloudy lens from your eye and replace it with a clear artificial lens. On the day of your operation, you will go to the hospital or clinic, have the procedure, and usually go home the same day. The surgery itself takes about 20 to 30 minutes and is done with numbing eye drops so you stay awake but feel no pain.
Key facts
Yes, cataract surgery is very common. In the UK, around 400,000 cataract operations are done each year. It is a routine procedure with a high success rate.
Cataract surgery is for people whose cataracts are affecting their everyday life, such as making it hard to read, drive, or see faces clearly. It is most often done in older adults, but can be performed at any age if needed.
Cataracts are diagnosed by an eye specialist through a comprehensive eye exam. On the day of surgery, your vital signs and eye will be checked to ensure you are ready.
On the day of surgery, you will arrive at the hospital or clinic, check in, and have a final assessment. The nurse will put dilating drops in your eye, and you may have a light sedative if needed. You will then be taken to the operating room where the surgeon will perform the procedure.
Cataract surgery is the only way to remove a cataract. It is usually done as a day case, meaning you go home the same day. The surgeon makes a tiny cut in your eye, uses ultrasound to break up the cloudy lens, and removes it. Then a clear artificial lens is inserted. No stitches are needed in most cases.
The medical team will use numbing eye drops or an injection around the eye so you feel no pain. You may be given a mild sedative to help you relax. The surgeon will guide you to look at a light during the procedure. Antibiotic drops may be used after surgery to prevent infection.
Surgery is recommended when cataracts interfere with your daily activities like reading, driving, or seeing in dim light. Your eye doctor will help you decide the right time.
On the day of surgery, after a short recovery in the clinic, you will go home. Your vision may be blurry or watery. You will need to wear a protective shield over your eye at night and avoid rubbing it. Follow-up appointments will be scheduled to check your progress.
You can eat and drink normally after surgery unless told otherwise. Light activity like walking is fine, but avoid anything that could strain your eye. Your doctor will advise when you can return to exercise.
Cataracts cannot be prevented, but you can lower your risk by protecting your eyes from sunlight, not smoking, and managing health conditions like diabetes. A healthy diet with fruits and vegetables may also help.
Regular eye exams are important for early detection. Your optician can check for cataracts even before you notice symptoms.
Cataract surgery is very successful. Over 95% of people have better vision after the operation. Most people are happy with the results and can return to normal activities within a few weeks. Your eye doctor will let you know what to expect based on your individual situation.
