Important Safety Information for Gas Permeable and Customized Soft Contact Lenses

WARNINGS:

Patients should be advised of the following warnings pertaining to contact lens wear:

  • Problems with contact lenses and lens care products could result in serious injury to the eye. It is essential that patients follow their eyecare practitioner’s directions and all labeling instructions for proper use of lenses and lens care products, including the lens case. Eye problems, including corneal ulcers, can develop rapidly and lead to loss of vision.

  • Daily wear lenses are not indicated for overnight wear, and patients should be instructed not to wear lenses while sleeping, with the exception of Orthokeratology lenses as noted below. Clinical studies have shown that the risk of serious adverse reactions is increased when daily wear lenses are worn overnight.

  • Studies have shown that contact lens wearers who are smokers have a higher incidence of adverse reactions than nonsmokers.

  • If a patient experiences eye discomfort, excessive tearing, vision changes, or redness of the eye, the patient should be instructed to immediately remove lenses and promptly contact his or her eyecare practitioner.
