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.
Soft Contact Lens Care Systems
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.
Rigid Gas Permeable (RGP) Contact Lens Care Systems
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.
