Introduction
Cataract surgery is one of the most common and successful eye surgeries performed worldwide. It helps restore clear vision by replacing the cloudy lens with an artificial one. While the procedure is generally safe, like any surgery, there is a small risk of infection. Understanding this risk, its symptoms, and how to prevent it can help ensure a smooth recovery.
What Is an Infection After Cataract Surgery?
An infection after cataract surgery, known as endophthalmitis, is a rare but serious complication where bacteria or other germs enter the eye during or after the procedure, leading to inflammation and potential vision loss if not treated promptly.
Symptoms to Watch For
If you’ve recently had cataract surgery, be alert for these signs of infection:
Increasing eye pain or discomfort (more than mild soreness)
Redness that worsens instead of improving
Sensitivity to light
Blurred or decreased vision
Yellow or white discharge from the eye
Swelling around the eye or eyelids
Fever (in rare cases)
If you experience any of these symptoms, contact your eye doctor immediately. Early treatment is crucial to prevent complications.

What Causes Infection After Cataract Surgery?
Infections can occur due to:
1. Bacteria entering the eye during surgery: Despite strict sterilisation, germs can sometimes enter the eye.
2. Poor post-surgery care: Touching or rubbing the eye with unclean hands can introduce bacteria.
3. Contaminated eye drops or medications: Using expired or improperly stored drops can increase infection risk.
4. Pre-existing eye conditions: Dry eye or other infections may raise susceptibility.
How Is It Treated?
If an infection is suspected, your doctor may:
Prescribe antibiotic eye drops or injections to fight the infection.
Recommend anti-inflammatory medications to reduce swelling.
Perform a procedure to remove infected fluid if necessary.
Severe cases may require hospitalisation, but most infections can be managed effectively if caught early.
How Can You Prevent Infection?
Here are some of the ways to prevent infection after surgery:
1. Before Surgery:
Follow all pre-surgery instructions (e.g., using prescribed antibiotic drops).
Inform your doctor if you have any infections (like conjunctivitis).
2. After Surgery:
Wash hands before touching your eyes.
Use prescribed eye drops exactly as directed.
Avoid rubbing or pressing on the eye.
Wear the protective eye shield as advised (especially while sleeping).
Avoid swimming or hot tubs for at least 2 weeks.
Keep follow-up appointments to monitor healing.
When to See a Doctor?
If you notice:
Sudden vision loss
Severe pain
Pus or excessive discharge
Seek emergency care immediately. Delaying treatment can lead to permanent vision damage.
