What is
Cataract? |
| |
|
Usually in
normal eyes our
lens is clear
and transparent,
but when
cataract
develops it
becomes cloudy
and opaque. So
the light is not
focused on the
retina through
lens which leads
to blurring of
vision. |
|
|
|
|
| |
How Cataract develops? |
|
| |
Most commonly cataract develops
due to the aging process taking
place in our lens. It is known
as Senile Cataract. |

What are the Symptoms of
Cataract ? |
|
| |
|
|
Gradually increasing
blurring of vision is
the most common symptom
of cataract. Some people
may have changes in the
brightness of the seen
objects.
Glare may be experienced
by some, specially at
night. Difficulty in
driving at night is
common due to this. This
is because of breaking
up of light rays due to
the cataract.
|
|
|
| |
Some people may have complaints
of seeing rings or halos around
lights. However, Cataract never
causes pain, itching or redness.

Can Cataract be prevented? |
|
| |
No, till date no preventive
measure is found for the
Cataract though research
continues. It is an age-related
change. No drugs, diets or
medicine can delay or cure the
Cataract. However, wearing a
sun-glass that blocks the UV
rays can slow down the process
of development of Cataract. |

What exactly is done in Cataract
Surgery? |
|
| |
Under an operating microscope
and with
Phaco-emulsification
machine a small cut is made in
the eye and opacified lens is
liquefied and removed and an
Intraocular Lens made of silicon
or acrylic is placed in place of
natural lens. |

Will
Surgery improve the vision ?
|
|
| |
Over 95% of Cataract surgery
will improve the vision. While
pre existing associated
condition like glaucoma,
diabetes, retinal condition etc
may limit the vision even after
surgery. Yet, Cataract surgery
may still be worthwhile and
necessary. |

When should I Plan my surgery
? |
|
| |
Under ordinary circumstances
cataract surgery is not an
emergency situation except in a
few rare instances. Therefore in
most of the cases the choice of
undergoing surgery largely
depends upon patients. In the
past, because of unavailability
of
phaco emulsification
technique surgeons usually
waited till the time cataract
became mature or ripe, but
modern technique advances have
now made possible to perform
cataract removal at early stage.
When it interferes with your day
to day work, it is time for
surgery. However, it is
advisable to have cataract
operated early before it becomes
hard. An Ophthalmologist can
give proper guidance. |

microscope under sterile
conditions. The different
techniques in use now for
cataract extraction are :- |

How long does one have to
stay in the Hospital after the
surgery ? |
|
| |
It is an Out Patient Surgery. No
stay is required. Patient will
be discharged immediately after
the surgery. |

|
| |
What post operative care is
required ? |
|
| |
After surgery you should be able
to resume most activities almost
immediately. You will be
cautioned against lifting heavy
weights and strenuous exercise
to avoid putting unnecessary
strain on the tiny structures as
your eye heals. |
