The Procedure of Phacoemulsification
Phacoemulsification is a procedure used in cataract surgery to break up and
remove the cloudy lens from the eye. The procedure involves using ultrasound
energy to break the dense, hard lens material into tiny pieces, allowing for easy
removal. A small incision is made in the eye so that an ultrasonic probe can be
inserted. This probe emits high-frequency sound waves that fragment the lens
into pieces, which can then be suctioned out of the eye. By using this method,
scarring and trauma to the delicate tissues inside the eye are minimized and
recovery time is greatly reduced. The entire procedure usually takes no more than
20 minutes.
How is phacoemulsification performed?
Phacoemulsification is the most common cataract removal surgery. It involves the
use of ultrasonic energy to break up the lens into small pieces, which are then
removed from the eye by suction. The procedure typically takes around 30
minutes. Before initiating the process, the ophthalmologist gives local anesthesia
to numb the affected eye for reducing discomfort during the surgery.
The steps of the phacoemulsification procedure include:
Making a tiny incision in the eye through which the surgeon will insert the
phacoemulsification probe.
Using the ultrasonic energy from the probe to break up the cataract into
small pieces.
Suctioning out the pieces of the cataract with the probe.
Inserting the artificial intraocular lens into the eye to replace the natural
lens that was removed.
Closing the incision with sutures or tissue adhesive and applying an
antibiotic ointment to the area to reduce the risk of infection
.
