This document discusses cataracts and their treatment. It begins with an overview of cataract symptoms, including blurred vision and increased sensitivity to light. It then describes the phacoemulsification surgical procedure to remove cataracts. This involves making a small incision in the eye and using ultrasound waves to break up the clouded lens, which is then suctioned out and replaced with an artificial lens implant. The document compares standard and LenSx laser-assisted cataract surgery methods and discusses monofocal and multifocal intraocular lens options to correct vision at different distances, noting potential side effects from multifocal lenses like glare and halos at night.

7. PHACOEMULSIFICATION
• During
phacoemulsification,
phaco for short, the
surgeon makes a small
incision, where the
cornea meets the
conjunctiva

the probe, which
vibrates with
ultrasound waves, to
break up (emulsify) the
cataract and suction out
the fragments
• Once the cataract is
removed, a clear
artificial lens is
implanted to replace
the original clouded
lens

• Corrects only 1 particular distance.

12. MULTIFOCAL IOLS
• Gives clear vision at
mutiple focus point
• May need glasses for
intermediate and near
• Glare and haloes at
night
