• To store lenses, disinfect and leave them in the
closed/unopened case until ready to wear. If
lenses are not to be used immediately follow-
ing disinfection, you should consult the
Package Insert or your eye care practitioner
for information on storage of your lenses.
• Always keep your lenses completely immersed
in a recommended disinfecting/conditioning
solution when the lenses are not being worn. If
you discontinue wearing your lenses, but plan
to begin wearing them again after a few weeks,
ask your eye care practitioner for a recom-
mendation on how to store your lenses.
• Boston EQUALENS II Contact Lenses cannot be
heat (thermally) disinfected.
• After removing your lenses from the lens case,
empty and rinse the lens storage case with
solution(s) recommended by the lens case
manufacturer or the eye care practitioner;
then allow the lens case to air dry. When the
case is used again, refill it with fresh storage
solution. Lens cases should be replaced at reg-
ular intervals as recommended by the lens
case manufacturer or the eye care practitioner.
• Your eye care practitioner may recommend a
lubricating/rewetting solution for your use.
Lubricating/Rewetting solutions can be used to
wet (lubricate) your lenses while you are wear-
ing them to make them more comfortable.
• Your eye care practitioner may recommend a
weekly enzymatic cleaner which can be used
to effectively remove protein deposits from
your Boston EQUALENS II Rigid Gas Permeable
Contact Lenses.
2. Care for a Sticking (Nonmoving) Lens
If the lens sticks (stops moving/cannot be
removed), you should be instructed to apply one
to three drops of a recommended lubricating or
rewetting solution directly to your eye and wait
until the lens begins to move freely on the eye
before removing it. If nonmovement of the lens
continues after 5 minutes, you should immedi-
ately consult your eyecare practitioner.
3. Lens Case Cleaning and Maintenance
Contact lens cases can be a source of bacterial
growth. Lens cases should be emptied, cleaned,
rinsed with solutions recommended by the lens
case manufacturer or the eye care practitioner,
and allowed to air dry after each use. Lens cases
should be replaced at regular intervals as recom-
mended by the lens case manufacturer or the
eye care practitioner.
4. Emergencies
If chemicals of any kind (household products,
gardening solutions, laboratory chemicals, etc.)
are splashed into your eyes, you should: FLUSH
YOUR EYES IMMEDIATELY WITH TAP WATER, THEN
REMOVE YOUR LENSES PROMPTLY, IF POSSIBLE,
AND IMMEDIATELY CONTACT YOUR EYE CARE
PRACTITIONER OR VISIT A HOSPITAL EMERGENCY
ROOM WITHOUT DELAY.
INSTRUCTIONS FOR THE MONOVISION WEARER
• You should be aware that, as with any type of lens
correction, there are advantages and compro-
mises to monovision contact lens therapy. The
benefit of clear near vision in straight-ahead and
upward gaze that is available with monovision
may be accompanied by a vision compromise that
may reduce your visual acuity and depth percep-
tion for distance and near tasks. Some patients
have experienced difficulty adapting to it. Symp-
toms, such as mild blurred vision, dizziness, head-
aches and a feeling of slight imbalance, may last
for a brief minute or for several weeks as adapta-
tion takes place. The longer these symptoms per-
sist, the poorer is your prognosis for successful
adaptation. You should avoid visually demanding
situations during the initial adaptation period. It is
recommended that you first wear these contact
lenses in familiar situations which are not visually
demanding. For example, it would be better to be
a passenger rather than a driver of an automobile
during the first few days of lens wear. It is recom-
mended that you only drive with monovision cor-
rection if you pass your state drivers' license
requirements with monovision correction.
• Some monovision patients will never be fully
comfortable functioning under low levels of illu-
mination, such as driving at night. If this happens,
you may want to discuss with your eye care practi-
tioner having additional contact lenses prescribed
so that both eyes are corrected for distance when
sharp distance binocular vision is required.
• If you require very sharp near vision during pro-
longed close work, you may want to have addi-
tional contact lenses prescribed so that both eyes
are corrected for near when sharp near binocular
vision is required.
• Some monovision patients require supplemental
spectacles to wear over the monovision correction
to provide the clearest vision for critical tasks. You
should discuss this with your eye care practitioner.
• It is important that you follow your eye care
practitioner's suggestions for adaptation to
monovision contact lens therapy. You should
discuss any concerns that you may have during
and after the adaptation period.
• The decision to be fit with a monovision
correction is most appropriately left to the
eye care practitioner in conjunction with the
patient after carefully considering and
discussing your needs.
