1. What is cataract surgery?

Cataract surgery is a procedure that removes the eye’s cloudy natural lens and replaces it with an artificial intraocular lens (IOL). It is the most effective treatment for a cataract and can significantly improve blurred or cloudy vision.

2. When is cataract surgery required?

Cataract surgery is generally recommended when a cataract starts affecting daily activities such as reading, driving, working, watching television, or recognizing faces. The decision depends on how much the cataract affects your vision and quality of life, rather than simply your age.

3. What are the symptoms of cataract?

Common cataract symptoms include blurred or cloudy vision, difficulty seeing at night, glare from headlights, increased sensitivity to light, faded colours, frequent changes in spectacle prescription, and halos around lights.

4. What is the best age for cataract surgery?

There is no fixed age for cataract surgery. Surgery can be performed when a cataract begins to interfere with vision and daily activities. Many people undergo cataract surgery after the age of 50, but the appropriate timing varies from person to person.

5. Is cataract surgery safe?

Cataract surgery is generally considered a highly successful and commonly performed eye procedure. However, like every surgery, it has potential risks and complications. An ophthalmologist should evaluate the eye and overall eye health before recommending surgery.

6. How is cataract surgery performed?

Modern cataract surgery is usually performed using a small incision through which the cloudy natural lens is removed and replaced with an artificial intraocular lens (IOL). The procedure is commonly performed under local or topical anaesthesia and usually takes a short time.

7. Is cataract surgery painful?

Cataract surgery is usually not painful because the eye is numbed with anaesthetic drops or other local anaesthesia. Patients may experience mild pressure, watering, or temporary irritation after surgery.

8. How long does cataract surgery take?

The actual cataract operation often takes approximately 15–30 minutes, although the total time at the eye centre can be longer because of preparation and post-operative monitoring.

9. How long does it take to recover from cataract surgery?

Many patients notice improved vision within a few days after cataract surgery, although complete visual recovery can take several weeks. Recovery varies depending on the type of surgery, the IOL used, and the health of the eye.

10. Can cataract surgery restore normal vision?

Cataract surgery can significantly improve vision by replacing the cloudy natural lens with a clear artificial lens. The final vision also depends on other eye conditions, such as glaucoma, diabetic retinopathy, macular degeneration, or corneal disease.
