Pre-Operative
Evaluation
You will need a note
from your/your child’s medical doctor before admission to the
hospital. Please bring this with you.
Laboratory work may or
may not be needed. This will be done if necessary the day before or
the morning of surgery.
Sometime in the
afternoon on the day prior to surgery you will be contacted by the
hospital. The time of the last feeding prior to surgery will be
reviewed. This will depend on the age of the patient and the time of
the surgery. The importance of an empty stomach prior to anesthesia
will be emphasized. All food and fluid will need to be held after a
certain hour.
PURPOSE OF THE SURGERY
The goal of the
operation will be to remove some or the entire cloudy lens from inside
the eye to allow light to enter the eye. By removing the natural lens,
the light still must be focused to gain a clear image to allow the eye
to see. This must be done to have sight, and can be accomplished by
several means, including contact lenses placed on the surface of the
eye, special spectacles, or an artificial lens implant inside the eye.
Each case is unique and requires a slightly different approach for
optical correction. In many cases this best correction is determined
after surgery. The surgery is performed by making small incisions into
the eye and removing the cataract. It is not done with lasers.
The development of the
visual system and of good vision is dependent on a sharp, clear image
focused in the eye during the early stages of childhood growth. It is
impossible to assure that this development will occur in each child’s
particular case. WITHOUT REMOVAL OF THE CATARACT THERE IS VIRTUALLY NO
CHANCE FOR VISION TO DEVELOP in some children’s particular cases.
Recovery room
Following surgery the
patient is taken to the recovery room where special nurses and
equipment are available. Here the recovery from anesthesia is
supervised. When a satisfactory state of consciousness returns, the
patient is sent to a separate room. The family can rejoin the patient
at this time.
POST-OPERATIVE COURSE
Eating: Until the
patient is well awake nothing by mouth should be encouraged. Once
awake, the patient may have ice chips or small sips of a beverage.
Nausea may occur after the administration of anesthesia. Large
quantities of food should be avoided in the immediate post-operative
period as they can irritate the stomach. Usually the patient is able
to resume a regular diet the day following surgery.
Bandages: The operated
eye will be covered will a soft metallic shield. It is important that
this shield stays in place overnight to prevent rubbing. Rubbing can
cause the stitches to open, which in turn can cause leakage of the
normal fluid contents of the eye. In addition to structural damage
this can cause infection. This shield will be removed in our office
the following day at the checkup.
Tearing: Tearing may
occur the first few days after surgery. If it is bothersome, they can
be gently wiped away with a tissue or other soft material like a
towel.
Pain: Generally there
is little or no pain. The eyes may be sensitive to the light due to
inflammation. Over the counter medications such as Tylenol or Advil
are usually sufficient. Only very rarely are prescription pain killers
needed. If severe pain associated with tearing is present, you should
contact the surgeon immediately.
Activity: All patients
are allowed up with supervision the same day. Infants and small
children may be held in the parents’ arms. Swimming and contact sports
are not permitted for four weeks. Keep soap and water out of eyes
while bathing.
Glasses: The eyes may
be light sensitive following surgery. In this case, older patients
will appreciate sunglasses or wide-brimmed hats. Younger patients may
choose to close their eyes to avoid the light. If glasses are worn
before surgery, they will probably be continued immediately after
surgery. They may be modified at some time during the post-operative
period.
Medications: After
cataract surgery intensive eye drop medications are required.
Antibiotic drops are used to prevent infection. Steroid drops are used
to calm inflammations. A dilating drop is used to assist in pain
control. These will be gradually lessened over several weeks, but at
least four weeks of drop therapy can be expected. Additional
medications to control the intraocular pressure may be added.
Office visits:
Generally the first checkup is on the next day following surgery. The
eye patch is removed. Regular visits will then be scheduled at regular
and frequent intervals. If there is any problem between scheduled
visits, it should be reported and additional visits can be arranged.
LONG-TERM COURSE
Treating the child
after the surgery is of the utmost importance in the final visual
outcome. This treatment will continue until the visual system is
mature, sometime BETWEEN FIVE AND TEN YEARS OF AGE. The expected
treatment will probably include contact lenses and/or special glasses,
use of a patch over one eye, and close medical supervision. More
surgery may well be needed. All this treatment is in addition to the
present cataract surgery. General medical problems may well require
additional care from other medical specialists. In spite of all this
extended treatment, the final vision in the operated eye may not be
good even though the eye itself appears normal and all the medical
advice has been carefully followed.
INTRAOCULAR LENSES
One of the newest ways
of correcting the focusing power in infants with cataracts is by using
an artificial implant in the same way that they are used for adults.
However unlike adults, in children it is often difficult to predict
what power intraocular lens will be needed as the child’s eye is still
growing. The growth of the eye will affect the power needed for clear
focusing. If an intraocular lens is placed, the surgeon(s) will pick a
power based on the length and curvature of the eye(s) as well as by
using their expertise in this field and best judgment. If an
intraocular lens is placed, depending on the condition of the eye(s)
and child’s age, it could require removal in the future because of
lens power modifications, problems with scarring, displacement, or
inflammation. All of the above mentioned treatments as well as
glasses, eye patches, eye drops, and additional surgeries may be
needed.
RISKS
Each child’s particular
case will be discussed with the surgeon(s). If a decision for cataract
surgery is made, it is the first step in the attempt to develop good
sight in the eye(s). There is no guarantee of good sight and there is
a risk of poor or no sight following the surgery. Problems of
bleeding, infection, glaucoma (high pressure inside the eye), retinal
detachment, or reaction of the tissue in the eye (inflammation) could
even lead to complete loss of the eye. These are recognized risks that
can occur after cataract surgery. Risks of anesthesia will be
discussed as a separate issue.
