EQUALENS
II (oprifocon A) Contact Lenses
are manufactured from a rigid gas permeable plas-
tic material. They are intended for daily wear or
extended wear use. It is essential that you follow
the recommended handling, cleaning and storage
procedures. Failure to do so may eventually impair
the performance of your lenses. You should always
carry a spare pair of lenses with you.
WEARING RESTRICTIONS AND INDICATIONS
Boston EQUALENS II (oprifocon A) RGP Contact Lens
is indicated for daily wear or extended wear from 1
to 7 days between removals for cleaning and disin-
fection as recommended by the eye care practition-
er. The lens is indicated for extended wear for the
correction of refractive ametropia (myopia and
hyperopia) in not-aphakic persons with non-diseased
eyes in powers from -20.00D to +12.00D.
The lens is indicated for daily wear for the correction
of refractive ametropia (myopia, hyperopia, astigma-
tism and presbyopia) in aphakic and not-aphakic
persons with non-diseased eyes.
The Boston Scleral (oprifocon A) RGP Contact Lens
for Daily Wear is indicated for eyes having signifi-
cantly reduced vision due to the presence of a dis-
torted corneal surface that:
1. precludes satisfactory spectacle lens correction
2. demonstrates significantly improved rigid con-
tact lens corrected vision
3. is incapable of wearing traditional corneal lenses
because of the inability to achieve adequate
lens centration/stability and/or tolerance to
physical contact with a lens.
Furthermore, eyes suffering from certain ocular sur-
face disorders may benefit from the physical pro-
tection and the saline bath provided by a scleral
lens.
The lens may be disinfected using a chemical disin-
fection system
only.
The Boston EQUALENS II Contact Lenses described
in this booklet should be removed from your eyes
for routine cleaning and disinfecting as prescribed
by your eye care practitioner. IF YOU ARE ON A
DAILY WEAR SCHEDULE, DO NOT WEAR YOUR Boston
EQUALENS II CONTACT LENSES WHILE SLEEPING.
CONTRAINDICATIONS (REASONS NOT TO USE)
DO NOT USE the Boston EQUALENS II Contact Lens
when any of the following conditions exist:
• Acute or subacute inflammation or infection of
the anterior chamber of the eye
• Any eye disease, injury, or abnormality that affects
the cornea, conjunctiva, or eyelids
• Severe insufficiency of lacrimal secretion
(dry eyes)
• Corneal hypoesthesia (reduced corneal sensitivity),
if nonaphakic
• Any systemic disease that may affect the eye or
be exaggerated by wearing contact lenses
• Allergic reactions of ocular surfaces or adnexa
that may be induced or exaggerated by wearing
contact lenses or using contact lens solutions
• Allergy to any ingredient in a solution which is
to be used to care for the Boston EQUALENS II
Contact Lens material
• Any active corneal infection (bacterial, fungal,
or viral)
• Red or irritated eyes
WARNINGS
• Problems with contact lenses and lens care prod-
ucts could result in serious injury to the eye. It
is essential to follow your eye care practitioner's
directions and all labeling instructions for proper
use of lenses and lens care products, including
the lens case. Eye problems, including corneal
ulcers, can develop rapidly and lead to loss of
vision.
• If you experience eye discomfort, excessive tear-
ing, vision changes, or redness of the eye, imme-
diately remove lenses and promptly contact
your eye care practitioner.
• Daily wear lenses are not indicated for overnight
