About Cataract
Cataracts are one of the three main causes of blindness
in Hong Kong. It is not necessary to wait until the
cataract becomes mature. When there is a significant
decrease in vision that affects your work or daily activities,
cataract extraction should be encouraged. Surgical risks
increase as the cataract matures.
A cataract is a clouding of the eye's natural lens.
It blocks the refraction of light to the retina and
causes deterioration of vision. Cataract can develop
into acute glaucoma, causing headaches and pain in the
eye. It is important to consult your doctor if any of
the above symptoms should occur.
Small Incision Cataract Surgery
Cataract Extraction is the most effective treatment
available. Using state-of-the-art equipment, our Eye
Clinic provides small incision cataract surgery which
can be performed under local anesthesia with complete
patient comfort. Recovery after this operation is significantly
faster than with the older traditional surgery.
Phacoemulsification is the most advanced method and
utilizes an ultrasonic probe to soften and break up
the lens, thus allowing the lens with its cataract to
be removed by suction.
Implantation of an intraocular lens restores the patient's
vision. This plastic lens requires no after-care, and
becomes a permanent part of the eye.
What are the causes and Symptoms
Causes and Symptoms
Cataracts generally occur in older patients. Diabetes,
ocular trauma, long term usage of steroids and an inherited
predisposition, represent some of the risk factors.
At onset, a cataract may not cause obvious symptoms,
but as it increases in size and density, the symptoms
become troublesome.
