When you are fitted for contact lenses a particular
lens care system is recommended -- a group of products to clean, disinfect
and make your lenses safe and comfortable for wear.
Since different systems use different types of chemicals,
it is not advisable to mix or substitute solutions from other systems.
Doing so could lead to discolored lenses, eye discomfort or eye injury.
In particular, rigid lens solutions should not be used to clean or disinfect
soft lenses as the chemicals can damage the soft lens material.
Regardless of how they are packaged, most lens care systems include products
that perform six different functions. Some systems combine two or more
functions into one product while others keep them separate. The functions
required are dependent upon the type of lens regimen and your eyes and
will be discussed with you as part of a contact lens training program.
The six different functions performed by soft lens care
systems are:
Daily Cleaning to remove
debris accumulated and adhering loosely to the lens. This debris, if not
removed, can eventually make the lenses uncomfortable, interfere with
vision and reduce the ability of the disinfecting solution to kill potentially
harmful microorganisms. In addition, the cleaning solutions perform the
first step in the disinfection process.
Disinfecting to kill growing
forms of microorganisms (bacteria, fungi, and viruses) on the lenses.
Rinsing and Storing requires
the use of an ophthalmic isotonic saline solution or may be performed
with some types of disinfectant solution. Most saline solutions are not
suitable for storage of lenses, as they do not contain anything to kill
or prevent the growth of microorganisms.
Comfort or Lubricating Drops
are used to provide refreshment for dry eyes, in conditions of low humidity
or for added comfort near the end of the wearing day.
Protein Removal removes
stubborn protein deposits and, with daily cleaning and disinfection, helps
restore a clean, fresh contact lens surface. Protein removal is generally
not required for planned replacement lenses, which are replaced before
the deposits can cause difficulties.
RGP lenses must be cleaned and disinfected for safe and comfortable wear.
The lens care system recommended will include a group
of products designed to work together to clean, rinse, disinfect and remove
protein deposits and to re-wet your eyes if they become dry during contact
lens wear.
It is important to use only those systems designed specifically
for rigid gas permeable lenses. They are formulated with disinfectants
and preservatives proven to work best with the material of which your
lenses are made.
If you wish to change your lens care regimen or to try
a new lens care product, it is best to discuss this first, even if only
by telephone, to ensure that you select products that are compatible with
your eyes and will work well.
