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.
Thenhavethepatientlookatfamiliarnearobjectssuchasawatchfaceorngernails.Again
assess the reaction. As the patient continues to look around room at both near and distance
objects,observethereactions.Onlyafterthesevisiontasksarecompletedshouldthepatient
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 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 SofLens daily disposable
Toric (hilafilcon B) Visibility 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 care handling. The eye care professional should recommend
appropriate and adequate procedures for each individual patient in accordance with the particular
lens wearing schedule.
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.
EMERgENCIES
If chemicals of any kind (household products, gardening solutions, laboratory chemicals, etc.) are
splashed into your eyes, you should: FLUSH EYES IMMEDIATELY WITH TAP WATER AND THEN REMOVE
LENSES PROMPTLY. CONTACT YOUR EYE CARE PROFESSIONAL OR VISIT A HOSPITAL EMERGENCY ROOM
WITHOUT DELAY.
