UNBLURRING THE FACTS
Dr. Jimmy Lim

2. 1
WHAT IS A
CATARACT?

3. 2
A cataract is a degenerative condition of the eye
where the lens gradually clouds over. The lens is a
transparent, flexible structure in the front of your
eye that allows you to focus on objects and form a
sharp image of whatever you are looking at. Cataract
formation leads to blurring of vision and, when left
untreated, may result in vision loss.

TYPES OF CATARACTS

5. 4
Nuclear sclerotic cataracts
• It is the most common form of cataract.
• “Nuclear” refers to the centre of the lens,
while “sclerotic” refers to the hardening of the lens.
• It is age-related, meaning everyone develops nuclear
sclerotic cataracts as they age. This cataract builds
up slowly over time and can remain unnoticed for
many years.

6. 5
Cortical cataracts
• This type of cataract starts developing around the
cortex of the lens, which is the outer layer of the lens.
• Unlike nuclear sclerotic cataracts, cortical cataracts
progress relatively faster.
• This type of cataract is characterized by spikes of white
forming from the edge of the lens towards the centre,
similar to the “spokes” of bicycle wheels.

7. 6
Posterior subcapsular cataracts
• These cataracts start at the lens’s back or
“posterior” part.
• People with diabetes and patients using steroids or
steroids-based medication are likelier to develop
posterior subcapsular cataracts than others.
• These cataracts are also the fastest to progress
compared to the other two types — symptoms can
worsen over a couple of months.

8. 7
WHY DO CATARACTS FORM?

9. 8
• Ageing
• Reaction to injuries or diseases, such as diabetes
• Trauma to the eye

10. 9
HOW DO I KNOW IF
I HAVE A CATARACT?

11. 10
• Cloudy or blurred areas in your vision
• Light sensitivity
• Bad night vision
• Temporarily improved vision (If you are old-sighted
(presbyopia), cataracts might temporarily improve your
vision of nearby objects. This happens because of the
increased density of the lens nucleus, which focuses
light on the retina. However, this “second sight” goes
away as the cataract progresses, affecting both near
and distant vision.)

HOW DO I GET MY
CATARACTS REMOVED?

13. 9
CATARACT SURGERY

14. 10
The current treatment for cataracts is to remove them
by surgical means. Rapid advancements in current
technology allow cataract operations to be done using
tiny wounds with early visual recovery, making it safe,
fast and effective.
