Cataracts: What, Why and How are they treated?


A cataract is a medical condition that causes many cases of blindness around the world. Often cataracts are caused by aging.

In fact, what is a cataract? The word cataract itself comes from Greek, cataract, that means a waterfall.

The reference of 'waterfall' is because when someone has cataracts, the eyes become blurry like looking behind a waterfall.


The normal eye lens is able to transmit light from the cornea to the retina, so that the person can see objects clearly.

The largest component of the eye lens consists of water and protein. Some of these proteins can harden to block the light from entering. As a result, the view becomes blurry, causing glare or double vision.

Cataracts are a medical condition that occurs when the normally clear lens of the eye becomes cloudy, blocking light from entering the eye. If left unchecked, cataracts can cause the individual to experience permanent blindness.

The good news is that cataracts are included in blindness that can be avoided. This means that cataracts can still be overcome and the only way is surgery.


Why Can Cataracts Occur?

Cloudiness of the lens of the eye is caused by the natural aging process. This is the reason why cataracts are often associated with an old person's disease.

As we get older, the clear lens of the eye will turn cloudy. This turbidity makes the incoming light not to be refracted right on the retina.

Even though it is synonymous with the elderly, it does not mean that cataracts cannot attack young people. Cataracts can be caused by several risk factors such as trauma, drug side effects, high myopia, congenital and diabetes.

Cataracts can occur in one or both eyes and usually develop slowly.

Cataracts can cause sufferers to experience a decrease in quality of life due to loss of vision if not treated immediately.

How to Treat Cataracts Properly?

Considering that cataracts are a degenerative disease related to age, almost everyone who has entered old age will experience cataracts.

Until now there has been no proven effective cataract treatment, apart from surgery. Treatment for cataracts includes surgical removal of the lens and replacing it with an artificial lens (IOL: intraocular lens) so that the patient can see clearly again.

Indications for cataract surgery can be carried out depending on the patient's needs. When cataract sufferers feel that their eyesight is getting worse and interfering with daily activities, surgery can be carried out immediately.

Before the operation is carried out, the patient needs to check with the doctor to examine the condition of the eye as a whole.

Cataract surgery will make the patient able to see objects better, even making it possible to get sharp vision in most surgeries.

Types of cataract surgery are generally divided into two:

  1. Extracapsular cataract extraction (ECCE): manual incision around 10-12mm to remove the cloudy lens. This procedure takes about 4-6 stitches and takes longer to heal.
  2. Phacoemulsification or phaco: small incision in the cornea (2 - 2.75 mm). The operation uses a machine that emits ultrasonic waves to break up the lens cloudy eye and sucking out of the eyeball. This technique generally has a relatively short healing time.
