Phaco-emulsification
is the latest
technique in the
fast developing
world of
cataract
surgery. The
incision is very
small, hence no
sutures are
required and
rehabilitation
is quick and
fast. The
distortion of
cornice is also
minimal. In this
surgery with the
help of the
machine the
opaque lens is
liquefied and
then sucked out.
Instead of our
natural lens, an
artificial
intra ocular
lens is placed.
Usually the size
of the IOL optic
is 6 mm. The
newer
generations of
IOLs are made
from a flexible
material & hence
can be folded &
injected into
the eye with the
help of
injector.
Through the 3 mm
injection &
hence the
advantage of the
small incision
are maintained.
The lens then
unfolds inside
the eye taking
the place of the
natural lens
which has been
removed. This surgery can
be done under
topical
anesthesia in
which case no
injection is
required to
anesthetize the
eye. Thus there
is no need of
bandaging the
eye after
surgery, so it
is also called
NO PAD, NO
INJECTION
cataract surgery. |

Topical
anesthesia is benefical as it hastens visual recovery and
there is no pain of injection
and no eye ball manipulation as
in case of peribulbar anesthesia.
So topical anesthesia leads to
instant visual recovery and no
discomfort of injection
anesthesia. |

Monofocal Lenses |
|
| |
Normal lenses provide either
sharp distance vision or near
vision and they are called
monofocal lenses. Therefore the
patient has to depend upon
glasses for either near or
distance vision. Blue bolcks
IOLs, Toric IOL, Hydraphobic IOL
& drophilic IOL, Silicon IOL are
other thpes of IOL. |

Multifocal Lenses : Freedom
from Glasses after Phaco
Surgery. |
|
| |
They have the capability to
provide both distance and near
vision with no OR much re-duced
dependence on glasses. |
|
| |
|
|
| |
How do they work? |
|
| |
|
It has a diffractive surface
which controls the light energy
going into the eye.
This helps you to focus sharply
on objects which are near or far
without much dependence on
spectacles. |

Advantage of Multifocal IOLs |
| |
-
Reduce dependence on glasses
for routine activities.
-
Provide excellent Distance,
Intermediate and Near Vision
