2. o Clear vision ..
o Comfort ..
o Convenience ...
o All good reasons why people choose to wear contact lens.
o However, when you don’t follow good hygiene habits with your
contact lenses, you may experience discomfort and challenges with
your contact lens wear.
o Don’t forget that contact lenses are medical devices!

3. The Basics of Contact Lens Care:
o Clean, Rinse and Disinfect
o Wash your hands so that you don't transfer dirt and germs
to your eye. Try to avoid moisturizing soaps, as they are not
good for contact lenses. Dry your hands with a lint-free
towel.
o Remove one lens and clean it with the recommended solution,
cosmetics and other debris that impairs lens comfort.
o The FDA recommends that you rub the lens in the palm of
your hand with a few drops of solution, even if you are using
a "no-rub" product.

4. o Rinse the lens again to remove the loosened debris, making sure to take as long as the
package directs: Rinsing is an important step.
o Place the lens in your clean lens case or lens holder and fill with fresh solution; don't "top
off" your old solution. Disinfecting kills microorganisms on the lens. Disinfection time
varies from product to product; check the package for details.
o Repeat steps two through four for your other lens.

5. Qualities of contact lens care system
o Effective against all likely ocular pathogens
o Contaminating lens care products, CLs & lens cases
o Non-toxic to ocular tissues
o Compatible with all CLs
o Simple to use (makes non-compliance difficult)
o Disinfects rapidly
o Prevents CL deposits

6. o Kills ALL viable organisms in:
 Lens case
 Solutions on CLs
o Removes ALL
 dead organisms
 skin lipids (from eyelids)
 tear, finger & air-borne contaminants
 cosmetic residues
o Non-toxic
o Suitable for all CLs
o Quick acting (to allow disinfection between brief uses)

7.  Think all contact lens care solutions are the same? Wrong!
 Contact lens solutions are designed for different purposes including cleaning, rinsing,
disinfecting and storing.
 Not all solutions do each of these things. Every contact lens solution is formulated differently
to provide different benefits.
 Be sure to discuss your contact lens solution options with your eye care professional to
understand which types of solutions best meet your contact lens care needs.

8. Types of contact lens care systems
Four types of contact lens care products:
o Multi-purpose contact lens solutions
o Hydrogen peroxide-based care systems
o Saline solutions
o Daily cleaners

9. o Multipurpose solution is for cleaning, rinsing, disinfecting and
storing your contact lenses.
o Clean your lenses as you would with daily cleaner, then rinse (as
long as directed) and disinfect, all with the same solution; or rinse
the lenses twice, then place them in the clean lens case with
solution to clean and disinfect. When you are ready to wear the
lenses, rinse them again.
o With multipurpose solutions, no other lens care products are
necessary.
o Multipurpose solutions also are called "no-rub" solutions.

10. Hydrogen Peroxide-Based solution
o Cleaning, Disinfecting, Rinsing And Storing.
o With this product, you place your lenses in the provided
basket and rinse them, then place the basket in its cup and
fill the cup with solution to clean and disinfect your lenses.
o Some lens holders for hydrogen peroxide systems have a
built-in neutralizer (to convert the hydrogen peroxide to
water, so it doesn't sting your eyes), but with others you
need to add a neutralizing tablet.

11. Lens disinfection with HPB lens care systems
o one-step
o two-step process

12. One-step HPB Systems:
o The lenses are placed in a holder
within a cylindrical contact lens case.
o The case is filled with a 3% solution
of hydrogen peroxide.
o The bottom of the case contains a
solid disk of a material that
immediately begins neutralizing the
hydrogen peroxide.

13. Two-step systems
o The contact lens are placed in a lens case
filled with only the hydrogen peroxide for a
specified period of time
o A neutralizer is then added to the case to
convert the disinfectant to harmless saline

14. Hydrogen peroxide-based solution disadvantage:
One-step HPB:
 May not expose contacts to full-strength
hydrogen peroxide for an adequate period of time
Two-step HPB :
 Users will forget the neutralizing step and incur a
painful eye injury

15. Saline Solutions
 Saline solutions are mainly used for rinsing and
storing contact lenses when you're using a heat or
UV disinfection system. Saline solutions are not
indicated or meant for disinfecting contacts.

16. Daily Cleaners
 A daily cleaner is used to clean contact lenses
prior to disinfection. Daily cleaners are not
indicated or meant to disinfect contact lenses so
you will be required to use additional products.3

17. Do’s
o Have regular check-ups as advised by your
practitioner.
o Wash and dry your hands prior to handling your lenses.
o Rub, rinse and store your lenses in the recommended
solution before and after each.
o Clean the lens case with solution, wipe with a clean
tissue then air-dry after each use.
o Always apply the same lens first to avoid mixing them
up.

18. o Apply your lenses before putting on make-up..
o Keep your eyes closed when using hairspray or other aerosols.
o Replace your lens case at least monthly.
o Discard lenses and solutions that are past their expiry date.
o Wear only the lenses specified by your contact lens practitioner.
o Ask yourself these three questions, each time you wear your lenses:
— Do my eyes feel good with my lenses? — no discomfort.
— Do my eyes look good? — no redness.
— Do I see well? — no blurring vision.
o If the answer to any of these questions is no, leave your lenses off and
consult your contact lens practitioner immediately, who will advise you on
what to do next.

19. Dont’s
o Use tap water, or any other water, on your lenses
o Put a lens on the eye if it falls on the floor or other
surface.
o Continue to wear your lenses if your eyes don’t feel good,
look good, or see well.
o Re-use solution – discard and replace with fresh solution
each time lenses are stored.
o Wear lenses left in the case for more than seven days
without cleaning and storing them in fresh solution.
o Share contact lenses

20. o Sleep in your lenses unless specifically advised to by your
practitioner.
o Use your lenses for swimming, showering, unless wearing
goggles.
o Use any eye drops without advice from your contact lens
practitioner.
o Remember that if you have any questions about your contact
lenses you should consult your BCLA contact lens practitioner
for advice.

21. Extend Wear Lenses
o Extend wear lenses became widely used in 1970.
o Extend wear lenses are very thin and high water content.
o Extend wear lenses are advanced soft lenses.
o Extend wear (continues wear, day & night wear)
o Most extend wear lenses are thinner than daily wear
o Made of silicone hydrogel.
o Allowing more oxygen to reach the cornea

22. Extend Wear Lenses
o Today Extend wear lenses are into for approve 30 days
o Also available in RGP.
o Extend wear is still controversial in ophthalmic community
o Microorganism can adhere to the lens maybe red eye, infectious
such as fungal keratits, acanthamoeba
o Reduce oxygen supply to cornea because eyelid are closed during
sleep can cause lose of vision
