How To Care About My Contact Lenses..!
Posterior
capsulotomy
Posterior
capsulotomy is a surgical procedure that is sometimes necessary after
cataract surgery.
WHY IS A POSTERIOR CAPSULOTOMY NECESSARY?
Cataract surgery removes a cataract (the
cloudy lens causing blurred
vision) from its cellophane-like lining called the lens capsule. An
artificial lens (called an intraocular lens, or IOL) is then inserted
into the capsule to replace the natural lens. Weeks to years
after cataract surgery, the capsule may become cloudy or wrinkled and
cause blurred vision. A posterior capsulotomy is a simple laser
procedure that makes an opening in the back, or posterior part of the
capsule to restore your normal vision.
WHEN SHOULD A CAPSULOTOMY BE PERFORMED?
If your vision becomes worse after cataract
surgery, it is important to consult your ophthalmologist. If a cloudy or
wrinkled capsule is discovered, a posterior capsulotomy may be
recommended when you are not able to see well enough to do the things
you like or need to do.
WHAT HAPPENS DURING POSTERIOR CAPSULOTOMY?
] The
technique is painless and only takes a few minutes. It is performed on
an outpatient basis, often in your ophthalmologist’s office. Anesthesia,
if necessary, is applied using eye drops.
] You should notice improved vision quickly, if there are no other problems with your eye. Unless your doctor advises otherwise, normal activities can usually be resumed immediately.
ARE THERE ANY RISKS INVOLVED?
As with any
surgical procedure, rare complications can occur, including:
]
detachment of the retina;
]
increased intraocular pressure;
]
Dislocation of the IOL through the posterior capsule opening.
Be sure to
discuss potential complications with your ophthalmologist before
surgery.
