8. TRETAMENT OF CATARACT
 If your vision can be corrected with glasses or contacts, your
doctor will give you a prescription. If it can’t, and cataracts are
a problem in your daily life, you may need cataract surgery.
 Phacoemulsification, or phaco. A small incision is made on
the side of the cornea, the clear, dome-shaped surface that
covers the front of the eye. Your doctor inserts a tiny probe
into the eye. This device emits ultrasound waves that soften
and break up the lens so that it can be removed by suction.
Most cataract surgery today is done by phacoemulsification,
also called “small incision cataract surgery.”
 Extracapsular surgery. Your doctor makes a longer incision on
the side of the cornea and removes the cloudy core of the lens
in one piece. The rest of the lens is removed by suction.
