Is
cataract surgery right for me?
With cataract
surgery, we hope to regain the vision lost due to
the cataract. The benefits to you in
improving your vision are: independence,
confidence, safety and enjoyment while pursuing
activities such as driving, reading, hobbies,
working and social activities. Surgery is
recommended when the cataract appears to be the
cause of the reduced vision and only when it is
preventing you from functioning as you normally
would. It is Dr. Chan’s opinion that you
could benefit by having cataract
surgery. Since the operation is considered
elective, the decision has been left to
you. Cataract surgery is considered major eye
surgery, but complications are
rare. Statistically, 95% of patients have no
complications. Around 4% have minor
complications that resolve on their own without
treatment. Less than 1% have significant
complications that require further treatment such
as a high intraocular pressure, infection inside
the eye, dislocation of the implanted lens,
drooping eyelid, retinal detachment, swelling or
clouding of the cornea and the remote possibility
of permanent loss of vision in the eye.
How much
will it cost to have cataract surgery?
Alberta Health
covers the cost for the ophthalmologist, day
surgery fee, basic replacement lens, and the
anesthetist. You will need to pay for your
eye drops. You will likely need a change in
your glasses after surgery – the cost of this is
your responsibility. If you choose to have
optional enhancements to your cataract surgery
such as a premium intraocular lens, the fees for
these enhancements would be your
responsibility.
What
should I know about cataract surgery?
Your operation
will be done as an outpatient at either the Royal
Alexandra Hospital, the Fort Saskatchewan Hospital
or at Cataract MD (formerly FYi Doctors). The
actual surgery time usually takes 10 to 15
minutes; however, be prepared to be there for
several hours due to preparation time,
etc. You will not be able to drive yourself
home after surgery or to the follow-up examination
the following morning.
Freezing of the
eye is usually done using eye drops and gel
(topical anesthesia) but may be done using a
freezing needle (retrobulbar anesthesia) if Dr.
Chan feels that you would not be able to keep your
eyes still enough to perform the surgery. Rarely,
complications from a freezing needle may occur and
this may be discussed with the anesthetist prior
to having this performed. An anesthetist is on
hand to administer the freezing and provide
intravenous medications that help you relax and
remain comfortable during the procedure. With
topical anesthesia, you will be required to keep
the eye still during surgery and to follow
instructions. With retrobulbar anesthesia,
the eye is immobilized which may cause double
vision for 4 to 12 hours so a patch is placed over
the operated eye before you leave the
hospital. You remove the patch at home the
next morning. In the vast majority of cases,
you are awake during surgery and it is important
that you refrain from sudden head or eye
movements. In certain circumstances, it may be
necessary for you to have your surgery under a
general anesthetic although this will be
determined at your first visit with Dr. Chan.
Your cataract will
be removed using a procedure called
phacoemulsification, whereby ultrasonic (sound)
waves break down the cataract allowing Dr. Chan to
remove it through an incision less than 2.5 mm in
size. The lens capsule is left
behind. An intraocular lens, made of a soft
injectable acrylic material, is implanted within
the capsule through the micro-incision, and
generally no sutures are used.
If you cannot lie
on your back quietly and comfortably for 30 to 60
minutes, be sure to let the nurses at the hospital
know this when you arrive.
What
should I expect following surgery?
The vision is
typically blurry for several days after the
surgery and improves gradually as you use your eye
drops. It is normal to feel mild discomfort,
irritation, scratchiness or tearing after surgery.
These types of symptoms commonly occur for 3 or 4
months after surgery due to increased dryness of
the eyes. If you have cataracts in both eyes, you
may experience visual distortion following your
first surgery. The distortion may persist until
the second eye is done. You will be asked to wear
an eye shield at bedtime for 1 week so that you do
not inadvertently rub your eye while
asleep. You should wear either a pair of
sunglasses of your old glasses during the daytime
for the first week so that you do not rub the eye,
and also to prevent dirt or dust from entering the
eye. For the first week after surgery, do not
lift more than 20-30 lbs, avoid bending over as
much as possible, do not strain yourself
physically, and be careful not to get anything in
the eye. Two weeks after surgery, you may
return to your regular activities.
You will see Dr.
Chan the morning after your surgery, and then 2 to
3 weeks afterwards to ensure that the eye is
healing properly. After cataract surgery, we
expect that your prescription for glasses will
need to be changed. Dr. Chan recommends that you
see your regular optometrist 6 weeks after surgery
for a final follow-up examination and glasses
prescription if needed.
The nurses at the
hospital will review the postoperative
instructions with you.
Will my
cataract return?
No. However,
in a small percentage of people the membrane
behind the lens implant may become cloudy anywhere
from two months to five years after the
surgery. This ‘capsular opacification’ or
‘secondary cataract’ causes blurry vision similar
to cataracts. If this happens, Dr. Chan can
clear the vision using a laser. This is a painless
procedure taking less than a minute that is done
as an outpatient visit in the Eye Clinic at the
Royal Alexandra Hospital.
