What is Cataract?
Cataract is described as a condition in which the normal human lens of the eye turns cloudy and later becomes opaque. The normal lens is transparent and allows light to reach the retina. When it becomes opaque (Cataract) light does not reach the retina and the patient is unable to see clearly.
Why does Cataract form?
Cataract is the most common cause of blindness in our country. The causes
of formation of cataract are not fully known.
-
It is an aging problem.
-
Ultraviolet light exposure.
-
Deficiency of protein and vitamins.
-
Exposure to steroids and various other medications,
Apart from cataract in old age cataract can also occur in children or adolescents.
Injuries can produce cataracts in all age groups. Patients with diabetes mellitus
develop cataracts earlier than a normal person.
Symptoms
Treatment of Cataract
Till today there is no drug, which has been proven to cure cataract. The
only treatment available is surgery i.e., removal of cataract.
When does cataract require removal?
Apart from the mature cataracts, even immature cataracts need to be removed
if it hampers with the patients visual requirements. There is no necessity to wait
for the cataract to ripen as in earlier times.
At PRADNYA NETHRALAYA we are performing the latest techniques for cataract removal.
We remove the cataract through a small incision by an ultrasonic aspiration technique
called Phacoemulsification. Almost all the patients are implanted with intraocular
lenses. The success rate after surgery is close to 99.5%.
Phacoemulsification
Small incision cataract surgery is increasingly gaining in popularity as
compared to a large incision of 13mm used previously to remove cataract. Phacoemulsification
is a method of removing cataract through small incision by means of ultrasonic energy,
which emulsifies the cataract. It involves highly sophisticated technology, cost
and lot of training on the part of the surgeon. The incision size is 2.5 mm. There
is no suture required because of the tunnel incision, which is self-sealing. Over
90% of surgeons in the USA are currently using Phacoemulsification as the procedure
of choice in cataract surgery. Over 90% of surgeons in the USA are currently using
Phacoemulsification as the procedure of choice in cataract surgery. Phacoemulsification
is used as the routine method of cataract removal. Dr. SRIRAM RAMALINGAM has extensive
experience in Phacoemulsification procedures. The Intra Ocular Lenses implanted
(IOL's) may be the Foldable or Non-foldable type. The Foldable lens is definitely
a better option, because it retains the incision size to 2.5 mm. whereas a Non foldable
lens requires extension of the incision to 5.5 mm and hence may require a suture.
The advantage of small incision cataract surgery using Phacoemulsification is that
visual recovery and rehabilitation is fast which enables the patient to resume normal
activities within a few days and even attend to routine office work.
Are they too expensive?
Just compare the disadvantages of traditional surgery anesthesia, inability
to attend work/ business for some days. Poor vision etc. you will appreciate that
the marginal increase in cost of surgery is more then compensated.
Will I need glasses after surgery?
Not very often. You may need to wear glasses only to fine tune your vision. These
are normal glasses and not those "thick" spectacles as in the past. Phaco and small
incision cataract surgery is probably a great leap forward in the field of ophthalmic
surgery.
What is after cataract?
In about 25% of the patient who undergo cataract surgery thickening of the
posterior capsule of the original lens occurs causing mild blurring of vision. This
can occur anytime between 3 months to 5 years after surgery. The treatment for this
is very simple. We do what is called laser treatment for these patients. The YAG
Laser is used to make a small opening in the thickened capsule behind the IOL. It
is a painless outpatient procedure.
