Cataract Surgery: Advantages and Disadvantages

Are you suffering from cataract in one or both eyes? Is the cloudiness of the eye’s natural lens is robbing you of your vision and quality of life? You no longer need to live with the vision impairment due to cataracts, thanks to cataract surgery.

Anyone thinking about undergoing Cataract surgery should first understand what is cataract.

The simplest definition for cataract is that it is a clouding of the natural lens, also called crystalline lens, in the eye that affects your daily activities and your ability to drive or read, and eventually leads to vision loss.

The only permanent way to repair a cataract is to have a cataract surgery. People with blurred or misty vision decide to have cataract surgery when the cloudiness in the eye’s natural lens gets bad enough where the vision cannot be improved with glasses or contact lens.

The surgical removal of cataract is also recommended to prevent other progressive eye disease s, such as diabetic retinopathy- a leading cause of blindness; and macular degeneration- deterioration of the center of the retina which leads to loss of central vision.

Cataract surgery, medically known as phacoemulsification, is performed with minimal sedation and typically takes around 20 minutes.

With the use of an operating microscope, the surgeon makes a very small incision about 3mm wide in the surface of the eye in or near the cornea. The clouded lens is then painlessly dissolved (phacoemulsify) using a fine needle that emits ultrasound waves. After the tiny fragmented pieces are sucked out, a folded artificial lens made from plastic or silicon is placed into the thin capsular bag. This artificial lens unfolds naturally in the eye.


Cataract surgery is very simple and almost painless.

It is generally the safest and effective way to restore vision with no serious complications.

After having the surgery, you will be allowed to return home the same day.

One of the biggest advantages of having cataract surgery is undoubtedly the dramatic improvement in the quality of vision.

It helps you get rid of blurry vision and have a better and clearer vision.

The surgery has little or no risks. The percentage of risk associated with the surgical removal of the cataract film from the lens is less than 10%.

Following the surgery, your surgeon keeps you under observation for a couple of hours before marking you to be cleared for discharge.

The recovery time for a cataract surgery is very short. The tiny incision size allows the eye to recover faster.

With greater vision, you can walk, climb stairs, drive car and do household chores more actively.


Like any other surgery, unexpected complications can occur during, or after, cataract surgery, albeit on rare occasions. The possible complications include:

Similar to any other major operation, the surgery may lead to blood loss

Abnormal reaction to the anaesthetic such as stickiness or itchiness of the eye is possible

Eye infection is also a possibility

Tearing of the lens capsule during surgery, causing reduced vision

Cataract fragments being left inside, requiring a second operation

Possibility of dislocation of the implant and damage to the retina

Inflammation, soreness, irritation, double sight can also occur after he surgery, albeit in very rare cases.

The biggest disadvantage of cataract surgery is that it is very pricey and that not all cataract patients may easily afford to get it done.
