health of the patient and lens performance on
the eye should be carefully monitored by the
prescribing eye care practitioner.
• Patients who wear contact lenses to correct
presbyopia may not achieve the best corrected
visual acuity for either far or near vision. Visual
requirements vary with the individual and should
be considered when selecting the most appropri-
ate type of lens for each patient.
• Aphakic patients should not be fitted with Boston
EQUALENS II Contact Lenses until the determina-
tion is made that the eye has healed completely.
• Before leaving the eye care practitioner's office,
the patient should be able to promptly remove
lenses or should have someone else available who
can remove the lenses for him or her.
• Eye care practitioners should instruct the patient
to remove the lenses immediately if the eye
becomes red or irritated.
• The presence of the ultraviolet (UV) light absorber
in the Boston EQUALENS II Contact Lens material
may require equipment enhancement to visualize
fluorescein patterns adequately. (Refer to the
Fitting Guide for detailed instructions.)
Eye care practitioners should carefully instruct
patients about the following care regimen and
safety precautions:
• Different solutions often cannot be used
together, and not all solutions are safe for use
with all lenses. Use only recommended solutions.
– Do not heat the wetting/soaking solution
and/or lenses. Keep them away from extreme
heat.
– Always use fresh unexpired lens care
solutions.
– Always follow directions in the package inserts
for the use of contact lens solutions.
– Use only a chemical (not heat) lens care system.
Use of a heat (thermal) care system can warp
the Boston EQUALENS II Contact Lenses.
– Do not use saliva or anything other than the
recommended solutions for lubricating or wet-
ting lenses.
– Always keep the lenses completely immersed in
the recommended storage solution when the
lenses are not being worn (stored). If dry stor-
age is desired to store the lenses for a longer
period of time, they must first be cleaned,
rinsed with water and carefully dried by blotting
with a soft lint-free tissue prior to being placed
in a clean, dry lens storage case. Ideally, these
lenses should be cleaned and disinfected prior
to insertion.
• If the lens sticks (stops moving) on the eye, follow
the recommended directions on Care for a
Sticking Lens. The lens should move freely on the
eye for the continued health of the eye. If non-
movement of the lens continues, the patient
should be instructed to immediately consult his
or her eye care practitioner.
• Always wash and rinse hands before handling
lenses. Do not get cosmetics, lotions, soaps,
creams, deodorants, or sprays in the eyes or on
the lenses. It is best to put on lenses before putting
on makeup. Water-based cosmetics are less likely
to damage lenses than oil-based products.
• Do not touch contact lenses with the fingers or
hands if the hands are not free of foreign materi-
als, as microscopic scratches on the lenses may
occur, causing distorted vision and/or injury to
the eye.
• Carefully follow the handling, insertion, removal,
cleaning, disinfecting, storing and wearing
instructions in the Patient Instructions for the
Boston EQUALENS II Contact Lens and those
prescribed by the eye care practitioner.
• Never wear lenses beyond the period recom-
mended by the eye care practitioner.
• If aerosol products such as hair spray are used
while wearing lenses, exercise caution and keep
eyes closed until the spray has settled.
• Always handle lenses gently and avoid dropping
them on hard surfaces.
• Avoid all harmful or irritating vapors and fumes
while wearing lenses.
• Ask your eye care practitioner about wearing
lenses during water activities and other sports.
• Inform your doctor (health care practitioner) that
you wear contact lenses.
• Never use tweezers or other tools to remove
lenses from the lens case unless specifically indi-
cated for that use. Pour the lens into the hand.
• Do not touch the lens with fingernails.
• Always contact your eye care practitioner before
using any medicine in the eyes.
• Always inform your employer that you wear con-
tact lenses. Some jobs may require use of eye
protection equipment or may require that the
patient not wear contact lenses.
• As with any contact lens, follow-up visits are
necessary to assure the continuing health of the
patient's eyes. The patient should be instructed as
to a recommended follow-up schedule.
ADVERSE EFFECTS
The patient should be informed that the following
problems may occur:
• Eyes stinging, burning, itching (irritation), or other
eye pain
• Comfort is less than when lens was first placed on
the eye
• Feeling of something in the eye such as a foreign
body, scratched area
• Excessive watering (tearing) of the eyes
• Unusual eye secretions
• Redness of the eyes
• Reduced sharpness of vision (poor visual acuity)
• Blurred vision, rainbows, or halos around objects
