What is the Reason Behind the Requirement for Cataract Surgery?

There can be two reasons to undergo cataract surgery: 

1. If you wish to get your cataracts corrected, you must have this operation. Because cataracts can cause cloudy vision and make your eyes sensitive to light glare, and your regular activities will become more difficult for you. This is when your doctor may recommend cataract surgery to you.

2. Another situation that might lead to such surgery is the interference or obstruction of cataracts in the treatment of other eye disorders, such as age-related macular degeneration, diabetic eye difficulties, and other common eye diseases. It is because Optometrists are unable to thoroughly examine the back of the eye when the eye lens is clouded.

There are several types of cataract surgery. The technique employed by a cataract surgeon is determined by a number of factors, including the health of the eye receiving the surgery, the surgical equipment utilised, and the doctor’s expertise.

Types of Cataract Surgery

Once your eye doctor has advised you to have the operation, there are several options for cataract removal. Let’s have a look at them:

a. Phacoemulsification

b. Extracapsular Cataract Surgery

c. Intracapsular cataract surgery

d. Laser-assisted Cataract Surgery

A. Phacoemulsification

It is the most often utilised method for cataract removal nowadays, and is also known as ‘Phaco.’

Typically, cataract removal through phacoemulsification takes no more than half an hour and requires only minimal sedation, which can be either local anaesthesia or topical anaesthesia.


A small surgical incision along the border of the cornea is required for this cataract surgery, which creates an opening through the membrane around the lens. The next step is to insert a small ultrasonic probe into the opening and use sound waves as a microscopic jack hammer to break apart the clouded lens into tiny fragments. Suction of broken-down cataract pieces is subsequently performed using an attachment on the probe tip.

After the lens particles are removed, an intraocular lens implant, also known as an IOL, is placed into the natural lens capsule. Ophthalmologists install the IOL through a small corneal incision using a hollowed-out tube.

B.  Extracapsular Cataract Surgery

This cataract technique is performed when the cataract is too thick for phacoemulsification or when phacoemulsification is not possible for other reasons. Or if the ultrasound is unable or unlikely to break down the cataracts, your surgeon may advise you to have extracapsular surgery.


This cataract removal technique necessitates a slightly larger incision so that the cataract can be removed in one piece rather than being fragmented within the eye. An artificial lens (IOL) is inserted inside the same capsular bag as in phacoemulsification.

To close the comparably bigger incision, a lot of sutures are necessary, which leads in a longer recovery of the wound as well as visual function.

The anesthesia is delivered by an injection around the eye to begin this cataract removal method. This type of surgery also necessitates the use of an eye patch.

C.  Intracapsular Cataract Surgery

Though it is rarely done anymore, this cataract removal procedure may still be beneficial in some conditions. It necessitates a bigger incision than extracapsular surgery, which removes the whole lens as well as the surrounding capsule. Furthermore, the IOL (intraocular lens) is implanted in a different location in this surgical operation, which is in front of the iris.

D. Laser-Assisted Cataract Surgery

LACS, or laser-assisted cataract surgery, is a modern Type of surgery as compared to Traditional cataract surgery (Phacoemulsification).


A camera/ultrasound imaging equipment is positioned over the eye during the procedure to collect information about the damaged lens. It can assist the doctor in determining the exact size, depth, and placement of the incision. Before surgery, the laser can also be utilised to soften the cataract. The computer then receives detailed information, which is used to program the laser. This programmable laser is used by the surgeon to produce a cut or opening in the lens capsule.

The ultrasound probe is used to break up the clouded lens and suction it out of the eye before implanting intraocular lenses. In most cases, no sutures are needed. 

According to studies, when incisions are done using a laser rather than by hand, the accuracy and precision of the incisions are roughly ten times greater.

What is Intraocular Lens?

When the natural crystalline lens is removed during cataract surgery, an intraocular lens, or IOL, is used to replace it. The IOL improves eyesight by focusing light on the retina. Patients can select from a wide range of intraocular lenses. Some of them are as following: 

a. Monofocal IOLs: These standard lens implants are monofocal, which means they are intended to correct eyesight at a single focal length. These lenses are intended to correct either near or far vision.

b. Accommodative IOLs: These lenses are meant to treat both myopia (near-sightedness) and hyperopia (farsightedness).

c. Toric IOLs: These are high-quality lenses that may be used to correct astigmatism. Toric intraocular lenses are relatively costly. Toric IOLs are used to correct astigmatism and distant vision.

To sum up…

While all types of cataract surgery are equally effective, safe, and have the same outcome, the patient’s selection is the decisive factor. To make a better selection, ask your cataract surgeon for more information about the many types of cataract surgery and which method and techniques are ideal for your requirements.
