Our eyes are our natural cameras. They help us capture images that our
brain processes further. There is a natural lens inside our eyes that bends
the light and helps us visualize the objects. For our vision to be clear,
the lens has to be very clear. Unfortunately, cataracts can cause clouding
to the otherwise clear lens.
Cataracts hamper clear vision; it feels like looking through frosted glass.
Cataracts mostly develop gradually without hampering your vision in the
early stages. As time progresses, cataracts start to mature, eventually
affecting your vision. You might find it difficult to perform activities
like reading, writing, and driving.
In the initial stage, glasses or bright lights can help correct the vision
to a certain extent. As the cataract progresses, you might encounter further
vision problems, and cataract extraction becomes an absolute must.
Before looking at various options for cataract extraction surgeries, let
us first understand the symptoms of cataract.
An untreated cataract may worsen over time and also cause permanent vision
impairment or blindness.
Hence, it is necessary to know the symptoms of cataract so that it can
be diagnosed at an initial stage.
Some of the common symptoms of cataract are:
- Hazy or blurred vision
- Reduced night vision
- Colours appear faded or yellowish
- Halos around light
- Increased sensitivity towards bright light
If any of these symptoms appear suddenly, it is an indicator that the
cataract is growing. As the cataract grows, the symptoms might worsen and
lead to grave consequences. Therefore, it is best to visit your ophthalmologist
at the onset of these symptoms.
The ophthalmologist may suggest cataract extraction surgery based
on your condition. Cataract extraction surgery is very safe and helps you
avoid unwanted vision impairments, and blindness caused due to cataracts.
Cataract Extraction Surgery
While performing the cataract extraction surgery, the eye surgeon extracts
the natural lens, which becomes hazy and replaces it with an intraocular
lens (or IOL). Before undergoing surgery, consult your doctor on various
types of IOLs since there is a variety of IOLs to choose from.
Monofocal IOLs or standard lens implants provide correct vision at one
focal length. Monofocal IOL helps in distant vision correction. However,
you would need to wear glasses while reading.
Multifocal IOLs have built-in multiple corrective zones like bifocal or
trifocal eyeglasses. These IOLs help in correcting near as well as far
Extended depth-of-focus (EDOF) IOLs
Extended depth-of-focus (EDOF) IOLs, also known as accommodating IOLs,
have one extended corrective zone that allows intermediate and distant
vision. The advantage of EDOF IOLs is that you might not even need reading
Toric IOLs are best suited for astigmatism. Using Toric IOLs also assures
that you will not require glasses to correct astigmatism.
Once you decide on the IOL, you would have to zero in on the type of extraction
surgery based on your condition.
Cataract Extraction Surgery Types
Once your doctor advises you to go for the surgery, there are a few options
available for you to choose:
Phacoemulsification (also called Phaco) is the most commonly used technique
for cataract extraction. The complete procedure takes between 15 minutes
to an hour.
In Phaco, a small surgical incision is made at the side of the cornea
under local/ topical anaesthesia. A small ultrasonic probe is inserted
through the incision to break the cloudy lens; then, the damaged lens is
suctioned out with an attachment to the probe.
Once the natural lens is suctioned out, the IOL is inserted in its capsule
through the incision.
Femto assisted cataract surgery
This is a no blade procedure, also known as robotic cataract surgery.
The precision and accuracy of the surgery is higher compared to the phacoemulsification.
It can also correct some astigmatism. The healing time is shorter than
the conventional procedures.
The doctor prescribes antibiotic drops before the surgery to prevent any
infection. Proper post-operative care must be taken as per the advice of
If you are witnessing any cataract symptoms, it is recommended to visit
the eye doctor at the earliest. Cataract extraction surgery successfully
restores vision in a vast majority of the people undergoing surgery.
