Cataracts are a prevalent eye condition that affects many people all over the world. In fact, the percentage of elderly patients affected by cataracts is about 78.6%, which also increases as people age. 63.6% of patients are 60 to 64 years while 94.6% of people are those 75 years and older.\u00a0<\/p>

A cataract is an eye condition that is characterised by a cloudy area in the lens of your eye that affects your vision. In some cases, you may or may not require surgery to restore clear vision, as eyeglasses and drugs may not be able to improve vision from an already clouded lens. Nonetheless, when this option comes up, there remains a degree of concern regarding the permanence of cataract surgery and whether cataracts can recur after surgery. With this, we address these concerns and shed light on the reality of cataract surgeries and their possible effects on your eyes.<\/p>

Do Cataracts Recur After Surgery?<\/strong><\/h2>

The unequivocal answer to whether cataracts can recur after surgery is a resounding no. This is because, during the surgical procedure, the cloudy and opaque lens where the cataract has developed is broken down and entirely extracted from the eye<\/a>. In its place is an artificial lens known as an intraocular lens (IOL). These specialised lenses are carefully selected to match the patient’s visual needs and provide optimal vision correction.\u00a0<\/p>

As a result of the surgery, the cataract ceases to exist within the eye. And as mentioned, it is entirely removed and replaced with a clear, artificial lens, effectively restoring clear vision.<\/p>

While it is crucial to understand that cataracts do not recur after surgery, the cataract-like symptoms you may be manifesting are due to a secondary cataract or posterior capsular opacification (PCO).<\/p>

What is a Secondary Cataract?<\/strong><\/h2>

A secondary cataract or posterior capsular opacification (PCO) is not a recurrence of the initial cataract; instead, it is an entirely different occurrence. During the cataract operation, the new artificial lens is placed within a capsule inside the eye. It is important to note that this artificial lens itself cannot develop a cataract, but the capsule that holds the lens can turn cloudy over time. This is due to epithelial cells left over from your natural lens. When the cells travel due to your body’s natural healing process and accumulate on the surface of your lens capsule, this causes your new lens to be cloudy.<\/p>

It is worth emphasising that secondary cataracts are typically uncommon. But when they do occur, they can lead to symptoms that mimic those of a primary cataract. This is why some individuals mistakenly inquire whether their cataracts have returned after undergoing surgery.<\/p>

How Long After The Surgery Do Secondary Cataracts Occur?<\/strong><\/h2>

Typically, this condition can develop months or even years after the cataract surgery. That\u2019s why it\u2019s essential to meet with your eye doctor regularly and maintain a healthy lifestyle to minimise the risk of secondary cataracts forming in your eyes.<\/p>

What Are the Symptoms of a Secondary Cataract?<\/strong><\/h2>

If you’ve undergone cataract surgery, you may be familiar with the symptoms of a cataract<\/a>. These symptoms are similar to those of a secondary cataract. Keep an eye out for the following signs:<\/p>
