What is the most important information I should know about Acuvue Theravision with ketotifen?


What You Should Know About Contact Lens Wear:

Eye problems, including corneal ulcers, can develop rapidly and lead to to loss of vision. If you experience:

  • Eye Discomfort,
  • Excessive Tearing,
  • Vision Changes,
  • Loss of Vision,
  • Eye Redness, or
  • Other Eye Problems,

You should immediately remove the lenses, and promptly contact your eye care professional

  • These lenses should not be used to treat red eye(s). Remove lens(es) immediately if your eyes become red or irritated.
  • Lenses prescribed for daily disposable wear (i.e., your Eye Care Professional instructs you to remove and discard your lenses at the end of each day), should not be worn while sleeping. Clinical studies have shown the risk of serious eye problems is increased when lenses are worn overnight.
  • Contact lens wearers who are smokers have a higher incidence of corneal ulcers than nonsmokers.
  • Problems with contact lenses or lens care products could result in serious injury to the eye.
  • Proper use and care of your contact is essential for the safe use of these products.
  • The overall risk of serious eye problems may be reduced by carefully following directions for lens care.

Specific Instructions for Use and Warnings:

  • Water Activity
    • Instruction for Use
      • Do not expose your contact lenses to water while you are wearing them.

        WARNING: Water can harbor microorganisms that can lead to severe infection, vision loss, or blindness. If your lenses have been submersed in water when participating in water sports or swimming in pools, hot tubs, lakes, or oceans, you should discard them and replace them with a new pair. Ask your Eye Care Professional for recommendations about wearing your lenses during any activity involving water.


For your eye health, it is important to carefully follow the handling, insertion, removal, and wearing instructions, as well as those prescribed by your Eye Care Professional (see “Lens Handling & Insertion”, “Lens Wearing” and “Caring for your Lenses” sections).

General Precautions:

Do Not use contact lens care solutions with this product.

If you wear your contact lenses to correct presbyopia using monovision you may not be able to get the best corrected visual acuity for either far or near vision. Visual needs are different for different people, so your Eye Care Professional should work with you when selecting the most appropriate type of lens for you.

Always contact your Eye Care Professional before using any medicine in your eyes.

Be aware that certain medications, such as antihistamines, decongestants, diuretics, muscle relaxants, tranquilizers, oral contraceptives, and those for motion sickness may cause dryness of the eye, increased lens awareness (feeling of the lens in the eye), or blurred vision. Always inform your Eye Care Professional if you experience any problems with your lenses while taking such medications.

Do not change lens type (e.g. brand name, etc.) or parameters (e.g. diameter, base curve, lens power, etc.) without consulting your Eye Care Professional.

Consult your Eye Care Professional or Health Care Provider if you are pregnant or nursing a baby.

As with any contact lens, follow-up visits are necessary to assure the continuing health of your eyes. Ask your Eye Care Professional about the recommended follow-up schedule.

Who Should Know That You are Wearing Contact Lenses:

Inform all of your doctors (Health Care Professionals) about being a contact lens wearer.

Always inform your employer of being a contact lens wearer. Some jobs may require use of eye protection equipment or may require that you not wear contact lenses.

How should I use Acuvue Theravision with ketotifen?


Do not wear lenses while sleeping.

The Acuvue Theravision with ketotifen described here are prescribed by your Eye Care Professional for daily disposable wear and are to be discarded after each removal. You should:

  • Insert one lens per eye per day. Discard lens after a single day’s use.
  • If prevention or relief of itching is needed beyond twelve hours, consult your Eye Care Professional.
  • These lenses may be worn beyond twelve hours for vision correction. Lenses should be removed prior to sleeping.
  • Do not use contact lens cleaning and disinfectant solutions with Acuvue Theravision with ketotifen.


For your eye health, it is important to carefully follow the handling, insertion, removal, and wearing instructions in this booklet, as well as those prescribed by your Eye Care Professional. If you will not or cannot always follow the recommended care procedures, you should not attempt to wear contact lenses.

When you first get your lenses, be sure that you are able to put the lenses on and remove them (or have someone else available who can remove the lenses for you) before leaving your Eye Care Professional’s office.

Step 1: Getting Started

It is essential that you learn and use good hygiene in the care and handling of your new lenses.

Cleanliness is the first and most important aspect of proper contact lens care. In particular, your hands should be clean, dry, and free of any soaps, lotions, or creams before you handle your lenses.

Before you start:

  • Always wash your hands thoroughly with a mild soap, rinse completely, and dry with a lint-free towel before touching your lenses.
  • You should avoid the use of soaps containing cold cream, lotion, or cosmetics before handling your lenses. These substances may come into contact with the lenses and interfere with successful wearing. It is best to put on your lenses before putting on makeup

Step 2: Opening the Packaging


Always confirm the lens parameters (e.g. diameter (DIA), base curve (BC), lens power (D), etc.) printed on the multi-pack and on the individual lens package match your prescription. Do not use if there is a mismatch.

Each multi-pack contains individually packaged lenses. Each lens comes in its own lens package designed specifically to keep it sterile while sealed.

These lenses are sensitive to light – store individual blister packages in the carton until use.

Lens Package

Do not use if the sterile blister package is opened or damaged.

To open an individual lens package, follow these simple steps:

1. Shake the lens package and check to see that the lens is floating in the solution.
2. Carefully peel back the foil closure to reveal the lens.
3. Place a finger on the lens and slide the lens up the side of the bowl of the lens package until it is free of the container.

Occasionally, a lens may stick to the inside surface of the foil when opened, or to the plastic package itself. This will not affect the sterility of the lens. It is still perfectly safe to use. Carefully remove and inspect the lens following the handling instructions.

Never use tweezers or other tools to remove your lenses from the lens container.

Lens Handling Tips

  • Handle your lenses with your fingertips, and be careful to avoid contact with fingernails. It is helpful to keep your fingernails short and smooth.
  • Develop the habit of always working with the same lens first to avoid mix-ups.
  • After you have removed the lens from the packaging, examine it to be sure that it is a single, moist, clean lens that is free of any nicks or tears. If the lens appears damaged, Do not use it.

Step 3: Placing the Lens on the Eye

Remember, always start with the same eye.

Once you have opened the lens package, removed, and examined the lens, follow these steps to insert the lens into your eye:

1. Be sure the lens is not inside-out by following one of the following procedures:

  • Place the lens on the tip of your index finger and check its profile. The lens should assume a natural, curved, bowl-like shape. If the lens edges tend to point outward, the lens is inside out.
  • Gently squeeze the lens between the thumb and forefinger. The edges should turn inward. If the lens is inside out, the edges will turn slightly outward.
  • Place the lens on the tip of your index finger and, looking up at the lens, locate the numbers 1-2-3. 1-2­ 3 indicates correct orientation, while a reverse of 1-2-3 indicates the lens is inside out. If the lens is inside out (reverse 1-2-3), invert the lens and locate the numbers again to confirm correct lens orientation.

2. With the lens on your index finger, use your other hand to hold your upper eyelid so you won’t blink.

3. Pull down your lower eyelid with the other fingers of your “inserting” hand.

4. Look up at the ceiling and gently place the lens on the lower part of your eye.

5. Slowly release your eyelid and close your eye for a moment.

6. Blink several times to center the lens.

7. Use the same technique when inserting the lens for your other eye.

There are other methods of lens placement. If the above method is difficult for you, ask your Eye Care Professional for an alternate method.

Step 4: Checking Your Lenses

After you have successfully inserted your lenses, you should ask yourself:

  • Do I see well?
  • How do the lenses feel on my eyes?
  • How do my eyes look?

If after placement of the lens, your vision is blurred, check for the following:

The lens is not centered on the eye (see “Step 5: Centering the Lens”).

If the lens is centered, remove the lens (see “Removing Your Lenses”) and check for the following:

  • Cosmetics or oils on the lens. Dispose of the lens and insert a new fresh lens.
  • The lens is on the wrong eye.
  • The lens is inside out (it would also not be as comfortable as normal). See “Step 3: Placing the Lens on the Eye.

If you find that your vision is still blurred after checking the above possibilities, remove the lens and consult your Eye Care Professional.

Note: If a lens is noticeably uncomfortable upon insertion or becomes less comfortable than when it was first inserted, remove the lens immediately and contact your Eye Care Professional. If your examination of your eyes and the lenses shows any other problems, immediately remove your lenses and contact your Eye Care Professional.

Step 5: Centering the Lens

A lens, which is on the cornea (center of your eye), will very rarely move onto the white part of the eye during wear. This, however, can occur if insertion and removal procedures are not performed properly. To center a lens, follow either of these procedures:

  • Close your eyelids and gently massage the lens into place through the closed lids.
  • Gently move the off-centered lens onto the cornea (center of your eye) while the eye is opened using finger pressure on the edge of the upper lid or lower lid.


While wearing your lenses, remember the following important precautions:

Hazardous Conditions

If you use aerosol (spray) products, such as hair-spray, while wearing lenses, keep your eyes closed until the spray has settled.

Avoid all harmful or irritating vapors and fumes while wearing lenses.

Never rinse your lenses in water from the tap. Tap water contains many impurities that can contaminate or damage your lenses and may lead to eye infection or injury.

Water Activity

  • Do not expose your contact lenses to water while you are wearing them.

Lubricating/Rewetting Solutions

Lubricating/Rewetting Solutions should not be used with these lenses. If the lens sticks (stops moving), a few drops of non-preserved sterile saline may be applied to assist with removal.

Do not use saliva or anything other than the recommended solutions for lubricating or rewetting your lenses. Do not put lenses in your mouth.

Sharing Lenses

Never allow anyone else to wear your lenses. Sharing lenses greatly increases the chance of eye infections.

Adhering to the Prescribed Wearing & Replacement Schedules

Never wear your lenses beyond the amount of time recommended by your Eye Care Professional. Never wear more than one lens per day.

Always throw away worn lenses as prescribed by your Eye Care Professional.


CAUTION: Always be sure the lens is on the cornea (center of your eye) before attempting to remove it. Determine this by covering the other eye. If vision is blurred, the lens is either on the white part of the eye or it is not on the eye at all. To locate the lens, inspect the upper area of the eye by looking down into a mirror while pulling the upper lid up. Then inspect the lower area by pulling the lower lid down.

1. Wash, rinse, and dry your hands thoroughly. You should follow the method that is recommended by your Eye Care Professional. Below is an example of one method: the Pinch Method.

  • Pinch Method:
    Step 1. Look up, slide the lens to the lower part of the eye using the forefinger.
    Step 2. Gently pinch the lens between the thumb and forefinger.
    Step 3. Remove the lens.

2. Follow the instructions in the next section, “Caring for Your Lenses”.

NOTE: For your eye health, it is important that the lens moves freely on your eye. If the lens sticks (stops moving) on your eye, apply a few drops of the recommended rewetting solution. Wait until the lens begins to move freely on the eye before removing it. If non-movement of the lens continues, you should immediately consult your Eye Care Professional.


If chemicals of any kind (household products, gardening solutions, laboratory chemicals, etc.) are splashed into your eyes: FLUSH EYES IMMEDIATELY WITH TAP WATER AND IMMEDIATELY CONTACT YOUR EYE CARE PROFESSIONAL OR VISIT A HOSPITAL EMERGENCY ROOM RIGHT AWAY.


The decision to be fit with monovision correction is most appropriately left to your Eye Care Professional, in conjunction with you, after carefully considering and discussing your needs.
