Recovering after cataract operation

Overview

A cataract operation removes the cloudy lens from your eye and replaces it with a clear artificial one. Recovery is the time your eye needs to heal after surgery.

Yes, cataract surgery is one of the most common and successful operations performed worldwide.

It affects anyone who has had a cataract removed, typically older adults, but it can be done at any age.

Symptoms

Common symptoms

• Mild discomfort, grittiness, or watering of the eye
• Blurred or hazy vision for the first few days
• Redness or bloodshot appearance
• Sensitivity to light
• Floating specks or flashes of light (usually harmless)

Symptoms in older adults

• Similar symptoms as adults, but older adults may have a slower recovery and more dryness.

Causes

Main causes

• The operation itself causes temporary inflammation and swelling.
• Your eye needs time to adjust to the new artificial lens.

Risk factors

• Having other eye conditions such as glaucoma or diabetes
• Not following post-operative care instructions, such as rubbing your eye
• Infection or bleeding (rare)

When to see a doctor

See a doctor urgently if:

• If you have severe eye pain, sudden vision loss, or discharge that looks like pus.

Book a routine appointment if:

• You will have a follow-up appointment within a day or two of surgery.

Diagnosis

Your surgeon will examine your eye after surgery to check healing and measure vision.

Tests that may be done

• Eye pressure check
• Slit-lamp examination (using a special microscope)
• Visual acuity test (reading letters on a chart)

What to expect at your appointment

The test is quick and painless. Your eye may be dilated with drops, which can make your vision blurry for a few hours.

Treatment

Recovery after cataract surgery mainly involves eye drops, rest, and avoiding strain. No additional surgery is usually needed.

Self-care at home

• Use prescribed eye drops exactly as directed.
• Wear a protective eye shield at night for at least a week.
• Avoid rubbing or pressing on your eye.
• Do not get water or soap in your eye while showering or washing your face.
• Avoid heavy lifting, bending over, or strenuous exercise for a few weeks.

Medical treatments

Living with this condition

Most people return to light activities within a few days. Driving is usually allowed after your vision has stabilised and you feel safe, often around 1–2 weeks.

Lifestyle tips

• Avoid swimming, hot tubs, and dusty environments until your doctor says it is safe.
• Wear sunglasses outdoors to reduce glare.
• Tell your optician you have had cataract surgery before getting new glasses.

Diet and exercise

Eat a balanced diet to support healing. Avoid heavy lifting and vigorous exercise for at least 4 weeks. Gentle walking is fine.

Mental health and emotional wellbeing

It is normal to feel anxious about your vision during recovery. Many people worry if sight isn't immediately perfect. Be patient: healing takes time.

Prevention

You cannot prevent needing cataract surgery if you have a cataract, but following your recovery plan carefully reduces the risk of complications.

Vaccines

No specific vaccine is needed.

Screening programmes

Regular eye exams after surgery help ensure your eyes stay healthy.

Complications

If left untreated

• Infection inside the eye (endophthalmitis) – rare but serious
• Swelling of the cornea or retina
• Increased eye pressure
• Retinal detachment (if you have certain risk factors)

Long-term outlook

Outlook is very good. More than 95% of people have improved vision after recovery. Most complications are treatable if caught early.
