Pleasanton, CA USA- CooperVision announced today that it is expanding its worldwide recall of the Avaira brand product line of contact lenses to include a limited number of lots of Avaira Sphere contact lenses. In continued collaboration with the United States Food and Drug Administration, CooperVision is expanding the recall because it identified certain lots of Avaira Sphere lenses that did not meet its updated quality requirements due to the level of a silicone oil residue.

The presence of the residue (silicone oil) on Avaira Sphere contact lenses may cause hazy vision or discomfort, severe eye pain or eye injuries requiring medical treatment. Not everyone experiences the same symptoms.

“The company is confident we found the problem and have taken corrective action in order to fix the problem,” said Christine Moench, Vice President, Global Regulatory Affairs and Quality Assurance. “The health and safety of our customers is our top priority.
