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 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
• Lens power is determined from the patient’s spherical equivalent prescription
corrected to the corneal plane. Select the appropriate lens and place 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 changes in fitting characteristics.
• Allow any increase in tear flow to subside before evaluating the lens. The time
required will vary with the individual.
3. Initial Lens Evaluation
a. To determine proper lens parameters, observe the lens relationship to the eye
using a slit lamp.
• Movement: The lens should provide discernible movement with:
— Primary gaze blink
— Upgaze blink
— Upgaze lag
• Centration: The lens should provide full corneal coverage.
b. Lens evaluation allows the contact lens fitter to evaluate the lens/cornea
relationship in the same manner as would be done with any soft lens. If after
the lens has settled on the eye, the patient reports lens sensation, or if the
lens is moving or decentering excessively, the lens should not be dispensed.
Alternatively, if the patient reports variable vision, or if the lens shows insufficient
movement, the lens should not be dispensed.
4. Criteria of a Well-Fitted Lens
If the initial lens selection fully covers the cornea, provides discernible movement
after a blink, is comfortable for the patient 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 relatively stable in relationship
to the cornea, particularly with the blink.
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 continued successful contact
lens wear. From the day of dispensing, the following schedule is a suggested
guideline for follow up.
• 24 hours
• 10 days
• 1 month
• 3 months
• Every six months thereafter
At the initial follow-up evaluations the eye care professional 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 performance 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 limbal-conjunctival 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.
PRACTITIONeR 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. 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.
Disposable Lens Wear
No lens care is needed. The lenses are discarded every time they are removed from
the eye. Lenses should only be cleaned, rinsed and disinfected on an emergency
basis when replacement lenses are not available.
Frequent/Planned Replacement
When removed between replacement periods, lenses must be cleaned and
disinfected before reinsertion, or be discarded and replaced with a new lens.
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 Ultra (samfilcon A)
Visibility Tinted Soft (hydrophilic) Contact Lenses.
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 potentially 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
over-correction 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 can
create a vision compromise that may reduce visual acuity and depth perception
for distance and near tasks. During the fitting process it is necessary for the
patient to realize the disadvantages as well as the advantages of clear near
vision in 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 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 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 the room at both near and distant 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 then graduate
to newsprint and finally smaller type sizes.
After the patient’s performance under the above conditions is 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 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 monovision 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 Ultra
(samfilcon A) Visibility Tinted Soft (hydrophilic) 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 not use plain
water, 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.
