Inside the eye is a lens, much like the lens of a camera. The
lens focuses incoming light rays through the pupil onto the retina
at the back of the eye. The image formed on the retina is then perceived
or “seen”.
The lens must remain clear for the light to pass through and reach
the retina. When the lens of the eye becomes cloudy or opaque, light
is unable to pass through the lens and vision dims or blurs. A lens
that has become cloudy is called a cataract. Cloudiness of the lens
usually occurs with age.
CAUSES OF CATARACT
By far, the most common cause of cataract is the deterioration
of the normal structure of the lens of the eye with age.
Other possible causes are injury to the eye or diseases such as
diabetes,prolonged use of steroids,eye inflammation, eye tumors
etc.
WHEN TO HAVE SURGERY
The need to have surgery is best determined by consulting your ophthalmologist.
The best time for operation for cataract depends on how the impairment
of vision affects the person’s life style. If person’s
work needs greater use of eyes, he may need to have cataract removed
much earlier than someone with less need for sharp vision.
CATARACT SURGERY
It is a simple operation which is generally done under local or
topical anesthesia. The patient remains fully conscious during surgery.
He does not experience any pain. During the surgery, the opaque
lens is removed and an artificial lens is implanted to substitute
the function of focussing light rays on to the retina.
PHACOEMULSIFICATION AND STITCHLESS
CATARACT SURGERY
The most exciting innovation in cataract surgery of this century
is the technique of phaco-emulsification. In this method, a tiny
Ultrasonic instrument is inserted through a very small incision
made on or just outside the cornea. This instrument uses Ultrasonic
vibrations to break the cataract into fine pieces which are gently
suctioned out of the eye. Since Phacoemulsification permits the
removal of cataract through a small incision, it eliminates many
of the complications of would healing process related to large incision
cataract surgery. The incision of phacoemulsification is closed
with out stitches. Phacoemulsification can be performed even without
giving any anesthetic injections before the operation and can be
done under the effect of just topical anesthesia delivered with
eye drops. No patch or bandage is required after surgery.
ADVANTAGES OF PHACOEMULSIFICATION
1. Shorter overall surgery.
2. Small incision (as small as 1.5 to 2mm).
3. Faster healing.
4. No stitches required.
5. Less induced Astigmatism.
6. Few post operative medicines and fewer precautions to be observed
post operatively.
7. Faster recuperation.
8. More comfortable and satisfied patient.
