What Are the Risks Associated with Cataract Surgery

While cataract surgery is one of the most common and successful eye procedures, it’s important to understand that no surgery is entirely without risks. In this article, we outline some of the potential complications and how they are generally managed.

General Risks


Any surgery carries a risk of infection. However, strict sterilisation procedures are followed to minimise this risk. Antibiotic eye drops are often prescribed before and after surgery.


While very rare, bleeding inside the eye can occur but is usually very well-controlled.


Some people experience swelling in the cornea or retina after the procedure. This is generally temporary and can be managed with medication.

Increased Eye Pressure

Elevated eye pressure can be a temporary side-effect after surgery and is usually controllable with eye drops.

Less Common Risks

Retinal Detachment

This is a rare but serious complication where the retina separates from the back of the eye. Immediate medical intervention is necessary.

Lens Dislocation

In rare instances, the artificial lens can move from its correct position and may require additional surgery to reposition.

Loss of Vision

This is extremely rare and usually occurs only if there are severe and rare complications like infection or retinal detachment.

The Role of a Trained Ophthalmologist

It’s important to note that a trained ophthalmologist is well aware of these potential risks and complications. That’s why they follow strict medical protocols and use state-of-the-art technology to minimise these risks. The years of rigorous training and continuing education they undergo are aimed at providing the safest and most effective treatment possible. During the procedure, multiple safety checks and balances are in place to ensure a favourable outcome. The goal is always to improve your vision while keeping complications to an absolute minimum.

Aftercare and Prevention

After your cataract surgery, it’s crucial to follow all aftercare instructions provided by your ophthalmologist to minimise risks. This often includes using prescribed eye drops and attending follow-up appointments for eye pressure checks and visual acuity tests.


Understanding the risks associated with cataract surgery is part of making an informed decision. While the procedure is generally safe, complications can occur. It’s essential to discuss any concerns with your ophthalmologist to understand how these risks apply to you and how they can be minimised.
