Cataract surgery is done to replace the
clouded natural lens of the eye with artificial man made lens .The modern
techniques involve the use of ultrasound devices that break the clouded lens
into smaller parts and then these smaller parts are removed from the eye . In phacoemulsification,
only small incision is needed take out the smaller parts of the clouded lens.
Like Lasik surgery, the laser is also
being used in the cataract surgery now. The use of laser has been approved in
the United States. The laser is used to create corneal incisions to gain access
to lens. It is also used to remove the anterior capsule of the lens, and break
the lens into smaller parts. The laser
can also be used to reduce the astigmatism by creating peripheral corneal
incisions.
The man made lens, which is inserted
after removing the clouded lens is a plastic, acrylic or silicon made. Before insertion,
the surgeon adjusts the optical power vision of the lens to restore the normal
vision of the patient. The Cataract
Surgery In Delhi reduces the
dependence of the patient on the reading glass.The cataract surgery is safe and
its success rate is around 98 percent.
Lasik
laser surgery benefits –
Lasik surgery is performed to cure the farsightedness,
nearsightedness and astigmatism. In
Lasik surgeries, the surgeon removes the cornea flap, to access the areas under
the cornea. To cure the problem, the area under the cornea has to be reshaped
before replacing the flap on the treated area. The laser is used to reshape the
area under the cornea. The cornea flap is cut with the help of micro blades.
But in the Lasik laser surgery, laser is used to cut the cornea flap also.
The only difference between laser Lasik
surgery and non laser Lasik surgery is that in laser Lasik surgery,the s laser
is used twice, first, to create cornea flap and then for reshaping the exposed
area under cornea for treatment.
The surgery takes place after numbing
the eye with drops. The eye holder is placed on the eye to keep them open
during the surgery. The patient is made to look at the pinpoint light, called
target light, while the laser is used to reshape the corneal tissue. After this
the cornea flap is placed back and it sticks with the underlying issues of
cornea within few minutes. The stitches
are not needed. For nearsightedness, the cornea is flattened and for farsightedness,
the steeper cornea is created.
The use of laser Lasik Laser
In Delhi thus allows surgeon to create accurate shape cornea flap and
perform the surgery without stitches.
