PRECAUTIONS:
Special Precautions for Eye Care Professionals:
• Due to the small number of patients enrolled in clinical
investigation of lenses, all refractive powers, design con
figurations, or lens parameters available in the lens
material are not evaluated in significant numbers.
Consequently, when selecting an appropriate lens design
and parameters, the eye care professional should consider
all characteristics of the lens that can affect lens performance and ocular health, including oxygen permeability,
wettability, central and peripheral thickness, and optic
zone diameter.
The potential impact of these factors on the patient's ocular
health should be carefully weighed against the patient's
need for refractive correction; therefore, the prescribing
eye care professional should carefully monitor the continuing ocular health of the patient and lens performance on
eye.
• Patients who wear aspheric contact lenses, such as the
BAUSCH & LOMB
may not achieve the best corrected visual acuity for either
®
SofLens®59, to correct presbyopia
far or near vision. Visual requirements vary with the
individual and should be considered when selecting the
most appropriate type of lens for each patient.
• Eye care professionals should instruct the patient to
REMOVE A LENS IMMEDIATELY if an eye becomes red
or irritated.
• Fluorescein, a yellow dye, should not be used while the
lenses are on the eyes. The lenses absorb this dye and
become discolored. Whenever fluorescein is used in eyes,
the eyes should be flushed with sterile saline solution that
is recommended for in-eye use.
• The patient should be instructed to always discard dispos
able lenses and lenses worn on a frequent/planned
replacement schedule after the recommended wearing
schedule prescribed by the eye care professional.
• 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 followup schedule.
• Aphakic patients should not be fitted with BAUSCH &
®
SofLens®59 Contact Lenses until the determina-

tion is made that the eye has healed completely.
Eye care professionals should carefully instruct patients
about the following lens care and safety precautions. It is
strongly recommended that patients be provided with a copy
of the SofLens
from BAUSCH & LOMB® and understand its contents prior

to dispensing the lenses.
Handling Precautions:
• 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-base cosmetics
are less likely to damage lenses than oil-base products.
• Be sure that before leaving the eye care professional's
office, the patient is able to remove lenses promptly or
have someone else available to remove them.
• Be certain that the fingers or hands are free of foreign
materials before touching lenses, as microscopic scratches
of the lenses may occur, causing distorted vision and/or
injury to the eye.
• Always handle lenses carefully and avoid dropping them.
• Do not touch the lens with fingernails.
• Carefully follow the handling, insertion, removal, cleaning
disinfecting, storing and wearing instructions in the
Patient Information Booklet for the SofLens® 59
Contact Lenses and those prescribed by the eye
care professional.
• Never use tweezers or other tools to remove lenses from
the lens container unless specifically indicated for that
use. Pour the lens into the hand.
Solution Precautions:
• Always use fresh unexpired lens care solutions.
• Always follow directions in the package inserts for the use
of contact lens solutions.
• Sterile unpreserved solutions, when used, should be dis
carded after the time specified in the labeling directions.
• Always keep the lenses completely immersed in the
recommended storage solution when lenses are not being
worn (stored). Prolonged periods of drying will damage
lenses. Follow the lens care directions for Care for a Dried
Out (Dehydrated) Lens in the patient information booklet
if lens surface does become dried out.
• Do not use saliva or anything other than the recommended
solution for lubricating or wetting lenses.
• Tap water, distilled water or homemade saline should not
be used as a substitute for any component in the lens care
regimen since they have been associated with an
Acanthamoeba keratitis infection.
• Never use conventional hard contact lens solutions that
are not also recommended for use with prescribed lenses.
• Do not mix or alternate lens care systems or solutions
unless indicated in the lens care system labeling.
• Do not use chemical disinfection solutions with heat
unless specifically indicated on product labeling for use in
both heat and chemical disinfection.
Lens Wearing Precautions:
• Never wear lenses beyond the period recommended by
the eye care professional.
• 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 nonmovement of the lens continues,
the patient should be instructed to
his or her eye care professional.
• Avoid, if possible, all harmful or irritating vapors and
fumes while wearing lenses.
• If aerosol products are used while wearing lenses, exercise caution and keep eyes closed until the spray has
settled.
Lens Case Precautions:
• Contact lens cases can be a source of bacterial growth. To
prevent contamination and to help avoid serious eye
injury, always empty and rinse the lens case with fresh,
sterile rinsing solution and allow to air dry.
• Lens cases should be replaced at regular intervals as
recommended by the lens case manufacturer or eye care
professional.
Topics to Discuss with the Patient:
• As with any contact lens, follow-up visits are necessary to
assure the continuing health of the eyes. The patient
should be instructed as to a recommended follow-up
schedule.
• Patients should be advised about wearing lenses during
sporting and water related activities. Exposure to water
while wearing contact lenses in activities such as swim-
immediately consult
ming, water skiing and hot tubs may increase the risk of
ocular infection including but not limited to
keratitis.
• Always contact the eye care professional before using any
medicine in the eyes.
Who Should Know That the Patient is Wearing Contact \
Lenses:
• Patients should inform their doctor (health care practitioner)
about being a contact lens wearer.
• Patients should always inform their employer of being a
contact lens wearer. Some jobs may require the use of eye
protection equipment or may require that you do not wear
lenses.
ADVERSE REACTIONS:
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 eye
• Abnormal feeling of something in the eye (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
• Sensitivity to light (photophobia)
• Dry eyes
If the patient notices any of the above, he or she should be
instructed to:
Immediately remove the lenses.
•

• If the discomfort or problem stops, then look closely at
the lens. If the lens is in any way damaged,

case and contact the eye care professional. If the lens has
dirt, an eyelash, or other foreign body on it, or the problem stops and the lens appears undamaged, the patient
should thoroughly clean, rinse, and disinfect the lenses,
then reinsert them. After reinsertion, if the problem
continues, the patient should
lenses and consult the eye care professional
If the above symptoms continue after removal of the lens, or
upon insertion of a new lens, the patient should
remove the lenses and contact his or her eye care profes-
or physician, who must determine the need for exam-
sional
ination, treatment or referral without delay. (See Important
Treatment Information for Adverse Reactions.) A serious
condition such as infection, corneal ulcer, corneal vascularization, or iritis may be present, and may progress rapidly.
Less serious reactions such as abrasions, epithelial stinging
or bacterial conjunctivitis must be managed and treated
carefully to avoid more serious complications.
Important Treatment Information for Adverse Reactions
Sight-threatening ocular complications associated with
contact lens wear can develop rapidly, and therefore early
recognition and treatment of problems are critical. Infectious
corneal ulceration is one of the most serious potential complications, and may be ambiguous in its early stage. Signs
and symptoms of infectious corneal ulceration include
discomfort, pain, inflammation, purulent discharge, sensitivity
to light, cells and flare and corneal infiltrates.
Initial symptoms of a minor abrasion and an early infected
ulcer are sometimes similar. Accordingly, such epithelial
defect, if not treated properly, may develop into an infected
ulcer. In order to prevent serious progression of these

immediately
conditions, a patient presenting symptoms of abrasions or
early ulcers should be evaluated as a potential medical emergency, treated accordingly, and be referred to a corneal specialist when appropriate. Standard therapy for corneal abrasions such as eye patching or the use of steroids or
steroid/antibiotic combinations may exacerbate the condition.
If the patient is wearing a contact lens on the affected eye
when examined, the lens should be removed immediately
and the lens and lens care products retained for analysis and
culturing.
SELECTION OF PATIENTS:
The eye care professional should not fit patients who cannot
or will not adhere to a recommended care or replacement
regimen, or are unable to place and remove the lenses
should not be provided with them. Failure to follow handling
and cleaning instructions could lead to serious eye
infections which might result in corneal ulcers.
Patient communication is vital because it relates not only to
patient selection but also to ensure compliance. It is also
necessary to discuss the information contained in the
Patient Information Booklet with the patient at the time of
the initial examination.
Patients selected to wear SofLens® 59 Contact Lenses
should be chosen for their motivation to wear contact lenses,
general health and cooperation. The eye care professional
must take care in selecting, examining and instructing contact lens patients. Patient hygiene and willingness to follow
practitioner instructions are essential to their success.
A detailed history is crucial to determining patient needs and
expectations. Your patient should be questioned regarding
vocation, desired lens wearing time (full or part time), and
desired lens usage (reading, recreation or
hobbies).
Initial evaluation of the trial lens should be preceded by a
complete eye examination, including visual acuity with and
without correction at both distance and near, keratometry
and slit lamp examination.
It is normal for the patient to experience mild symptoms
such as lens awareness, variable vision, occasional tearing
(watery eyes) and slight redness during the adaptation period.
Although the adaptation period varies for each individual,
generally within one week these symptoms will disappear. If
these symptoms persist, the patient should be instructed to
contact his or her eye care professional.
FITTING PROCEDURE:
1. Pre-Fitting Examination
A pre-fitting patient history and examination are necessary to:
• determine whether a patient is a suitable candidate for
daily wear contact lenses (consider patient hygiene and
mental and physical state),
• make ocular measurements for initial contact lens parameter selection, and
• collect and record baseline clinical information to which
post-fitting examination results can be compared.
A prefitting examination should include spherocylinder
refraction and VA, keratometry, and biomicroscopic
examination.
2. Initial Lens Power Selection
a. Lens power is determined from the patient’s spherical
equivalent prescription corrected to the corneal plane.
b. Select the appropriate power lens and place the lens on
the eye. Allow the lens to remain on the eye long enough
(10 to 20 minutes) to achieve a state of equilibrium.
Small variations in the tonicity, pH of the lens solutions,
and individual tear composition may cause slight

4. Criteria of a Well-Fitted Lens
If the initial lens selection fully covers the cornea, provides
discernible movement after a blink, is comfortable and
provides satisfactory visual performance, it is a well fitted
lens and can be dispensed.
5. Characteristics of a Tight (Steep) Lens
A lens which is much too steep may subjectively and
objectively cause distortion which will vary after a blink.
However, if a lens is only marginally steep, the initial subjective and objective vision and comfort findings may be
quite good. A marginally steep lens may be differentiated
from a properly fitted lens by having the patient gaze
upward. A properly fitted lens will tend to slide downward
approximately 0.5mm while a steep lens will remain

– Upgaze blink
– Upgaze lag

relatively stable in relationship to the cornea, particularly

6. Characteristics of a Loose (Flat) Lens
If the lens is too flat, it will:
– Decenter, especially on post-blink.
– Have a tendency to edge lift inferiorly and sit on the lower
lid, rather than positioning between the sclera and palpebral conjunctiva.
– Have a tendency to be uncomfortable and irritating with
fluctuating vision.
– Have a tendency to drop or lag greater than 2.0mm on
upgaze post-blink.
7. Follow-up Care
a. Follow-up examinations are necessary to ensure contin-
ued successful contact lens wear. From the day of dispensing, the following schedule is a suggested guideline
for follow up.
• 3 or 4 days post-dispensing
• 10 days
• 1 month
• 3 months
• every six months thereafter
At the initial follow-up evaluations the eye care profes-
sional should again reassure the patient that any of the
previously described adaptive symptoms are normal, and
that the adaptation period should be relatively brief.
b. Prior to a follow-up examination, the contact lenses
should be worn for at least 4 continuous hours and the
patient should be asked to identify any problems which
might be occurring related to contact lens wear.
c. With lenses in place on the eyes, evaluate fitting perform-
ance to assure that CRITERIA OF A WELL FITTED LENS
continue to be satisfied. Examine the lenses closely for
surface deposition and/or damage.
d. After the lens removal, instill sodium fluorescein [unless
contraindicated] into the eyes and conduct a thorough
biomicroscopy examination.
1. The presence of vertical corneal striae in the posterior
central cornea and/or corneal neovascularization may
be indicative of excessive corneal edema.
2. The presence of corneal staining and/or limbalconjunctival hyperemia can be indicative of an unclean
lens, a reaction to solution preservatives, excessive
lens wear, and/or a poorly fitting lens.
3. Papillary conjunctival changes may be indicative of an
unclean and/or damaged lens.
If any of the above observations are judged abnormal, various professional judgments are necessary to alleviate the
problem and restore the eye to optimal conditions. If the
CRITERIA OF A WELL FITTED LENS are not satisfied during
any follow-up examination, the patient should be re-fitted
with a more appropriate lens.
PROFESSIONAL FITTING SETS
Lenses must be discarded after a single use and must not
be used from patient to patient.
WEARING SCHEDULE:
The wearing and replacement schedules should be determined by the eye care professional. The BAUSCH & LOMB
SofLens®59 (hilafilcon B) Visibility Tinted Contact Lens is
recommended by BAUSCH & LOMB for 2 week replacement.
Regular checkups, as determined by the eye care professional,
are extremely important.

Daily Wear:

There may be a tendency for the daily wear patient to over
wear the lenses initially. Therefore, the importance of adhering to a proper, initial daily wearing schedule should be
stressed to these patients. The wearing schedule should be
determined by the eye care professional. The wearing schedule chosen by the eye care professional should be provided
to the patient.
MONOVISION FITTING GUIDELINES:
1. Patient Selection
A. Monovision Needs Assessment
For a good prognosis the patient should have adequately
corrected distance and near visual acuity in each eye. The
amblyopic patient or the patient with significant astigmatism
(greater than one [1] diopter) in one eye may not be a good
candidate for monovision with the BAUSCH & LOMB
SofLens®59 (hilafilcon B) Visibility Tinted Contact Lenses
Contact Lens.
Occupational and environmental visual demands should be
considered. If the patient requires critical vision (visual acuity
and stereopsis) it should be determined by trial whether this
patient can function adequately with monovision.
Monovision contact lens wear may not be optimal for such
activities as:
(1)visually demanding situations such as operating poten-
tially dangerous machinery or performing other potentially
hazardous activities; and
(2)driving automobiles (e.g., driving at night). Patients who
cannot pass their state drivers license requirements with
monovision correction should be advised to not drive
with this correction, OR may require that additional overcorrection be prescribed.
®
B. Patient Education
All patients do not function equally well with monovision
correction. Patients may not perform as well for certain
tasks with this correction as they have with bifocal reading
glasses. Each patient should understand that monovision, as
well as other presbyopic contact lenses, or other alternative,
can create a vision compromise that may reduce visual acuity
and depth perception for distance and near tasks. During the
process it is necessary for the patient to realize the dis-
fitting
advantages
straight ahead and upward gaze that monovision contact
lenses provide.
2. Eye Selection
Generally, the non-dominant eye is corrected for near vision.
The following test for eye dominance can be used.
A. Ocular Preference Determination Methods
Method 1 - Determine which eye is the "sighting dominant
eye." Have the patient point to an object at the far end of the
room. Cover one eye. If the patient is still pointing directly at
the object, the eye being used is the dominant (sighting) eye.
Method 2 - Determine which eye will accept the added
power with the least reduction in vision. Place a trial spectacle near add lens in front of one eye and then the other while
the distance refractive error correction is in place for both
eyes. Determine whether the patient functions best with the
near add lens over the right or left eye.
B. Refractive Error Method
For anisometropic corrections, it is generally best to fit the
more hyperopic (less myopic) eye for distance and the more
myopic (less hyperopic) eye for near.
C. Visual Demands Method
Consider the patient's occupation during the eye selection
process to determine the critical vision requirements. If a
as well as the advantages of clear near vision in
patient's gaze for near tasks is usually in one direction
correct the eye on that side for near.
Example:
A secretary who places copy to the left side of the desk will
usually function best with the near lens on the left eye.
3. Special Fitting Considerations
Unilateral Lens Correction
There are circumstances where only one contact lens is
required. As an example, an emmetropic patient would only
require a near lens while a bilateral myope may require only
a distance lens.
Example: A presbyopic emmetropic patient who requires a
+1.75 diopter add would have a +1.75 lens on the near eye
and the other eye left without a lens.
A presbyopic patient requiring a +1.50 diopter add who is
-2.50 diopters myopic in the right eye and -1.50 diopters
myopic in the left eye may have the right eye corrected for
distance and the left uncorrected for near.
4. Near Add Determination
Always prescribe the lens power for the near eye that provides optimal near acuity at the midpoint of the patient's
habitual reading distance. However, when more than one
power provides optimal reading performance, prescribe the
least plus (most minus) of the powers.
5. Trial Lens Fitting
A trial fitting is performed in the office to allow the patient to
experience monovision correction. Lenses are fit according
to the directions in the general fitting guidelines.
Case history and standard clinical evaluation procedure
should be used to determine the prognosis. Determine
which eye is to be corrected for distance and which eye is to
be corrected for near. Next determine the near add. With trial
contact
lenses
lentilles
de contact
5959
lenses of the proper power in place observe the reaction to
this mode of correction.
Immediately after the correct power lenses are in place, walk
across the room and have the patient look at you. Assess
the patient's reaction to distance vision under these circumstances. Then have the patient look at familiar near objects
such as a watch face or fingernails. Again assess the reaction. As the patient continues to look around room at both
near and distance objects, observe the reactions. Only after
these vision tasks are completed should the patient be asked
to read print. Evaluate the patient’s reaction to large print
(e.g. typewritten copy) at first and than graduate to news
print and finally smaller type sizes.
After the patient’s performance under the above conditions
are completed, tests of visual acuity and reading ability
under conditions of moderately dim illumination should be
attempted.
An initial unfavorable response in the office, while indicative
of a guarded prognosis, should not immediately rule out a
more extensive trial under the usual conditions in which a
patient functions.
6. Adaptation
Visually demanding situations should be avoided during the
initial wearing period. A patient may at first experience some
mild blurred vision, dizziness, headaches, and a feeling of
slight imbalance. You should explain the adaptational symptoms to the patient. These symptoms may last for a brief
minute or for several weeks. The longer these symptoms
persist, the poorer the prognosis for successful adaptation.
To help in the adaptation process the patient can be advised
to first use the lenses in a comfortable familiar environment
such as in the home.
Some patients feel that automobile driving performance may
not be optimal during the adaptation process. This is particularly true when driving at night. Before driving a motor
vehicle, it may be recommended that the patient be a
passenger first to make sure that their vision is satisfactory
for operating an automobile. During the first several weeks
of wear (when adaptation is occurring), it may be advisable
for the patient to only drive during optimal driving conditions.
After adaptation and success with these activities, the patient
should be able to drive under other conditions with caution.
7. Other Suggestions
The success of the monovision technique may be further
improved by having your patient follow the suggestions
below.
– Having a third contact lens (distance power) to use when
critical distance viewing is needed.
– Having a third contact lens (near power) to use when
critical near viewing is needed.
– Having supplemental spectacles to wear over the mono-
vision contact lenses for specific visual tasks may
improve the success of monovision correction. This is
particularly applicable for those patients who cannot meet
state licensing requirements with a monovision correction.
– Make use of proper illumination when carrying out visual
tasks.
Success in fitting monovision can be improved by the
following suggestions.
– Reverse the distance and near eyes if a patient is having
trouble adapting.
– Refine the lens powers if there is trouble with adaptation.
Accurate lens power is critical for presbyopic patients.
– Emphasize the benefits of the clear near vision in straight
ahead and upward gaze with monovision.
*The decision to fit a patient with a monovision correction
is most appropriately left to the eye care professional in
conjunction with the patient after carefully considering the
patient's needs.
*All patients should be supplied with a copy of the
BAUSCH & LOMB
Tinted Contact Lens Patient Information Booklet.
HANDLING OF LENSES
When lenses are dispensed, the patient should be provided
with appropriate and adequate instructions and warnings for
lens handling. The eye care professional should recommend
appropriate and adequate procedures for each individual
patient in accordance with the particular lens wearing schedule.
For complete information concerning the care, cleaning and
disinfection of contact lenses refer to the BAUSCH & LOMB
SofLens®59 (hilafilcon B) Visibility Tinted Contact Lens
Patient Information Booklet.
CARE FOR A STICKING (NONMOVING) LENS:
If the lens sticks (stops moving), the patient should be
instructed to use a lubricating or rewetting solution in their
eye. The patient should be instructed to
or anything other than the recommended solutions. The
patient should be instructed to contact the eye care
professional if the lens does not begin to move upon
blinking after several applications of the solution, and to
not attempt to remove the lens except on the advice of the
eye care professional.
CARE FOR A DRIED OUT (DEHYDRATED) LENS:
If a soft, hydrophilic contact lens is exposed to air while off
the eye, it may become dry and brittle and need to be rehydrated. If the lens is adhering to a surface, apply the

To rehydrate the lens:
• Handle the lens carefully.
• Place the lens in its storage case and soak the lens in a
recommended rinsing and storing solution for at least 1
hour until it returns to a soft state.
• Clean lens first, then disinfect the rehydrated lens using
a recommended lens care system.
• If after soaking, the lens does not become soft, if the
surface remains dry, DO NOT USE THE LENS UNTIL IT
HAS BEEN EXAMINED BY YOUR EYE CARE
PROFESSIONAL.
