| Contact Lenses, their case solutions
are medical devices.
Recently two contact lenses solutions
have been voluntarily removed from the U.S. market.
Serious eye infections that have caused
blindness and even the loss of an eye have occurred
in the world.
These infections are extremely rare!
Examination concluded that infection
was not due to contaminated bottles, but due to "topping-off"
of contact lens case solution and poor lens hygiene.
Topping-off occurs when solution is simply added to
the old solution already in the contact lens case. As
contact lens solutions "wear-out" after they
have actively cleaned a lens, "topping-off"
does not provide the contact lens with adequate amounts
of cleansers or antimicrobial agents. The result is
increased risk for a sight-threatening infection. |
