The lens may be prescribed in spherical powers ranging from +6.00D to -9.00D.
The lens may be disinfected using either a heat or chemical disinfection system. Eye Care Practitioners may prescribe the lens for traditional or frequent/planned replacement wearing schedule, with cleaning, disinfection and scheduled replacement of the lens.

Severe insufficiency of lacrimal secretion (dry eyes)
Corneal hypoesthesia (reduced corneal sensitivity)
Any systemic disease that may affect the eye or be
exaggerated by wearing contact lenses
Allergic reactions of ocular surfaces or adnexa ing tissue) that may be induced or exaggerated by wearing contact lenses or use of contact lens solutions

WARNINGS
After a thorough eye examination, including appropriate medical background, patients should be fully apprised by the prescribing practitioner of all the risks with contact lens wear. Patients should be advised of the following warnings pertaining to contact lens wear:
Problems with contact lenses and lens care products could result in serious injury to the eye. It is essential that patients follow their eye care practitioner’s direction 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.
Daily wear lenses are not indicated for overnight wear, and patients should be instructed not to wear lenses while sleeping. Clinical studies have shown that the risk of serious adverse reactions is increased when these lenses are worn overnight.
The need for strict compliance with the care regimen including cleaning of the lens case, wearing restrictions, wearing schedule, and follow-up visit schedule should be emphasized to the patient
Studies have shown that contact lens wearers who are smokers have a higher incidence of adverse reactions than nonsmokers
If a patient experiences eye discomfort, excessive tearing, vision changes, or redness of the eye, the patient should be instructed to immediately remove lenses and promptly contact his or her eye care practitioner.
PRECAUTIONS
Special Precautions for Eye Care Practitioners:
Due to the small number of patients enrolled in clinical investigation of lenses, all refractive powers, design con­figurations, 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 practitioner 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’ ocular health should be carefully weighed against the patient’s need for refractive correction; therefore, the con­tinuing ocular health of the patient and lens performance on eye should be carefully monitored by the prescribing eye care practitioner.
Fluorescein should not be used while the patient is wearing the lenses, because the lenses will become discol­ored. Whenever fluorescein is used, flush the eyes with sterile saline solution. Wait at least 5 minutes before rein­serting the lenses. If it is not possible to flush the eyes, wait a minimum of 1 hour before reinserting the lenses. If replaced too soon, the lenses may absorb residual fluorescein.
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 carefully instruct patients about the following care regimen and safety precautions:
Different solutions cannot always be used together, and not all solutions are safe for use with all lenses. Use only recommended solutions.
s
- Never use solutions recommended for conventional hard contact lenses only.
- Chemical disinfection solutions should not be used with heat unless specifically indicated on product labeling for use in both heat and chemical disinfection.
- 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 dis­carded after the time specified in the labeling directions.
- Do not use saliva or anything other than the recom­mended solutions for lubricating or wetting lenses.
- Always keep the lenses completely immersed in the rec­ommended storage solution when the lenses are not being worn. Prolonged periods of drying can damage lenses. Follow the lens care directions for Care for a Dried Out (Dehydrated) Lens if lens surface does become dried out.
If the lens sticks (stops moving) on the eye, follow the rec-
ommended 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 immediately consult his or her eye care practitioner.
Always wash and rinse hands before
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.
Do not touch contact lenses with the fingers or hands if
the hands are not free of foreign materials, as microscopic scratches of 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 Information Booklet for the BAUSCH &

Avoid all harmful or irritating vapors and fumes while
wearing lenses.
Ask the eye care practitioner about wearing lenses during water activities and other sports.
Inform the doctor (health care practitioner) about being a contact lens wearer.
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.
Do not touch the lens with fingernails.
Always discard lenses and lenses worn on a
frequent/planned replacement wearing schedule after the recommended wearing schedule prescribed by the eye care practitioner.
Always contact the eye care practitioner before using any medicine in the eyes.
