The human body is a complex system of different parts that work in sync to ensure that humans can perform all their tasks in a quick and efficient manner. Even if one body part or organ fails to function effectively, it hampers the overall functioning of the body.


In this article, we will bring under purview one of the most common eye diseases called cataract. We understand that anyone who does not belong from a medical background will find it difficult to comprehend the aetiology of cataracts. Therefore, with this article, we aim to make you understand the signs and medical treatment of cataracts in the most basic and simple terms.

What is a Cataract?
Before delving into the clinical manifestation of cataracts, let us throw some light on the fundamental definition of cataracts. A cataract can be referred to as the clouding of the clear lens of the eyes.

Therefore, for people who have a cataract, seeing through a damaged or foggy lens is equivalent to looking through a fogged-up or frosty window, making it difficult to write, read, drive, and carry out day to day tasks. Below we have mentioned some of the many symptoms and signs of cataract:


● Difficulties in night vision
● Yellowing or fading of colours
● Dim, blurred, or clouded vision
● Sudden sensitivity to glare and light
● Detection of double vision in one single eye
● Frequent changes in contact lenses or eyeglass prescriptions

Causes and Treatments of Cataract

Usually, most cataracts develop due to increasing age or eye injuries that bring in changes in the tissues that form the eye lens. In addition, fibres and protein in the lens begin to break down, leading to cloudy or hazy vision.

On the other hand, some genetic disorders, past eye surgeries, and medical conditions can also increase the risk of cataracts. Here are some of the many types of cataracts that are commonly detected in people:

● Cataracts that affect the back of the lens
● Cataracts that affect the centre of the lens
● Congenital cataracts or cataracts a person is born with the condition
● Cataracts that have an effect on the edges of the lens
Further, let us take a brief glimpse into the variety of treatments that ophthalmologists employ to treat cataracts in a safe and reliable manner:

● Phacoemulsification cataract treatment

Usually, in order to treat or remove a cataract, doctors adopt for a procedure called phacoemulsification. In this type of surgery, the ophthalmologist makes a tiny opening in the eye in order to reach the foggy or clouded lens.
Next, by using a laser or ultrasound, the doctor manages to break the lens into pieces. Lastly, the doctors suction these broken lenses out and fit in a new artificial lens.

● Extracapsular cataract surgery

In case phacoemulsification is not an ideal option for a person, the doctor usually opts for extracapsular cataract surgery. For instance, if a person is in an advanced stage of cataract, the lens might become too dense to break.
The only point of difference between the two procedures is that in extracapsular cataract surgery, the doctor makes the incision and removes the lens in one single piece.
