What is Cataract Surgery?

Cataract surgery is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision.

Cataract surgery is performed by an eye doctor (ophthalmologist) on day care basis, which means you don’t have to stay in the hospital after the surgery. Cataract surgery is very common and is generally a safe procedure.

Early stages of lens changes don’t cause significant visual impairment and don’t require surgery. Usually, a doctor will recommend surgery when your cataracts begin noticeably affecting your vision. Having trouble with everyday activities Trusted Source — such as driving, reading, or seeing in bright light — is a sign that you may need cataract surgery.

Specific ways cataracts may impair your vision include:

  1. blurry vision
  2. impaired night vision
  3. colors appearing faded
  4. sensitivity to glare and bright lights
  5. halos around lights
  6. double vision

Types of Cataracts Surgery

Cataracts affecting the center of the lens (nuclear cataracts). A nuclear cataract may at first cause more nearsightedness or even a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and further clouds your vision.

As the cataract slowly progresses, the lens may even turn brown. Advanced yellowing or browning of the lens can lead to difficulty distinguishing between shades of color.


Cataracts that affect the edges of the lens (cortical cataracts). A cortical cataract begins as whitish, wedge-shaped opacities or streaks on the outer edge of the lens cortex. As it slowly progresses, the streaks extend to the center and interfere with light passing through the center of the lens.


Cataracts that affect the back of the lens (posterior subcapsular cataracts). A posterior subcapsular cataract starts as a small, opaque area that usually forms near the back of the lens, right in the path of light. A posterior subcapsular cataract often interferes with your reading vision, reduces your vision in bright light, and causes glare or halos around lights at night. These types of cataracts tend to progress faster than other types do..


Cataracts you’re born with (congenital cataracts). Some people are born with cataracts or develop them during childhood. These cataracts may be genetic, or associated with an intrauterine infection or trauma.


These cataracts may also be due to certain conditions, such as myotonic dystrophy, galactosemia, neurofibromatosis type 2 or rubella. Congenital cataracts don’t always affect vision, but if they do, they’re usually removed soon after detection.


Secondary Cataracts

‘Secondary cataracts,’ sometimes referred to as ‘after-cataracts,’ is an eye condition that occurs after cataract surgery.


The medical term for secondary cataract disease is posterior capsular opacification (PCO). PCO is actually one of the most common complications after cataract surgery.


Traumatic Cataracts

Traumatic cataract is clouding of the lens and eyes that may occur after either blunt or penetrating ocular trauma that disrupts and damages the lens fibers. Most of the traumatic cataracts lead to eye lens swelling, but the type and clinical course depends on trauma and the integrity of the capsular bag.


Radiation Cataracts

Radiation cataract causes partial opacity or cloudiness in the crystalline lens and results from damaged cells covering the posterior surface of the lens. Symptoms can appear as early as one or two years following high-dose exposure and many years after exposure to lower doses.

Risks & Complications of Cataract Surgery

Complications after cataract surgery are uncommon, and most can be treated successfully.

Cataract surgery risks include:

  • Inflammation
  • Infection
  • Bleeding
  • Swelling
  • Drooping eyelid
  • Dislocation of artificial lens
  • Retinal detachment
  • Glaucoma
  • Secondary cataract
  • Loss of vision

Cataract (Motiyabind) Surgery Procedure

Cataract surgery, also known as lens replacement surgery, involves replacing the clouded lens with an artificial lens. The clouded parts of the natural eye lens are removed safely by using phacoemulsification or a laser machine. Then the intraocular lens (cataract lens), commonly called IOL is placed inside the hollow cavity of the lens to provide clear vision.


At St. Theresa’s Hospital, Hyderabad, we use the following techniques to treat cataracts –



Microincision cataract surgery is one of the most commonly used approaches for cataract removal. In this technique, a very small incision, less than 1.8 mm is created to access the eye lens, break it down, and extract it. Then the IOL is implanted in the eye to provide clear vision.


It is a safe and effective procedure with more than a 98% success rate and minimal complications. The recovery after microincision cataract surgery is also quick with negligible chances of developing surgically induced astigmatism.



Femtosecond laser-assisted cataract surgery (FLACS) is an advanced form of cataract operation. A femtosecond laser is used to make an incision in the cornea and to break down the clouded part of the eye lens. The laser makes it safer and quicker to extract the lens with precision. Then the IOL is implanted in the eye (or both eyes) to restore the vision.
