Kinds
of lenses used in Cataract Surgeries
While non-foldable lenses
are made up of PMMA, a hard plastic material,
Foldable lenses are
either made of acrylic or silicone.
The advantage of a foldable over a non-foldable
lens is that the incision is very small and
consequently the recovery period is much faster.
Whichever the lens used, cataract surgery
is a small procedure wherein the patient is
discharged after a couple of hours and can
safely go back home the same day.
Post surgery, in certain patients, a very
thin film develops behind the artificial lens.
The treatment is a painless 10 minutes OPD
procedure wherein the doctor cuts away this
film through a process called Yag Laser. |
Know
about Cataract
What is Cataract?
Cataract is
a natural clouding of the clear natural crystalline
lens in the eyes. This is a normal outcome
of the aging process but may also result out
of trauma to the eye, heredity or diabetes.
It is because of heredity that one sees infantile
cataracts in some newborn babies.
Symptoms
of cataract
Whatever the
cause, cataracts typically result in blurred
or fuzzy vision and sensitivity to light. |

Treatment
of cataract
The only treatment for cataract is
surgical intervention through which the cloudy
natural lens is removed and replaced with
a clear artificial lens. A cataract can be
operated at any stage. In India, there is
a myth that cataract’s should only be
operated when “mature”. This may
actually lead to complications.
Cataract
surgery
Cataract surgeries
are microsurgeries and are broadly categorized
into two:
Extra
capsular Cataract Extraction (ECCE):
This involves
removing the cloudy lens in one piece
leading to a large incision of 10 to 12
mm on the eye. Through this incision,
the artificial lens is also implanted
and then the cut is sutured.
Phacoemulsification
(Phaco):
This is
the latest advance in cataract removal
wherein a small ultrasonic probe is inserted
into the eye through a cut of 3.2mm or
less. This probe breaks (emulsifies) the
cloudy lens into tiny pieces and gently
sucks these out of the eye. The surgeon
then implants the replacement lens through
this cut.
