CooperVision Avaira Contact Lens Recall

It seems that no contact lens manufacturer has been immune to a recall of their contact lenses. CooperVision announced a global recall of selected lots of their Avaira® Sphere and Avaira® Toric contact lenses.

The recall is due to the amount of residual silicone oil left over from the manufacturing process. The symptoms reported range from blurry vision to pain and irritation.   Only a small number of Avaira contact lenses are affected. To see if your lenses are affected enter your lot number on the CooperVision Contact Lens Recall Website. If your contact lenses are on the recall list CooperVision recommends returning them to the point of purchase for replacement.

  1. I have read of cases of torn corneas from patients using the affected Cooperviiosn lenses. Is this due to sticky silicone oil phenonemon where the lens adheres to the cornea, requiring a “damaging” force to remove. What is the mechanism for the torn corneas?

    • I really doubt the silicone oil problem would cause a torn or scratched cornea, more likely it would cause a chemical type keratitis at the most severe end of the spectrum of possibile complications.

      • Dr. Driscoll, the silicone oil would indirectly contribute to the etiology of the abrasions or the torn cornea. The patient while attempting to manually remove the lens due to the irriation is the cause of the abrasions or torn cornea I believe.

      • Yes, in that case I see how an abrasion could be indirectly associated with the recalled lenses. Good thought

  2. Good to keep informed. Ironic how silicone oil is detrimental in this case after it has become a tool of the trade for detached retinas.

  3. Dr. Driscoll are you aware of any standard test to evaluate the bacterial adhesion concerning contact lenses. If, so what are the acceptance criteria? Thank you.

    • No I don’t know what the standard would be, though I expect there would be one.

      • According to the litertaure there is no industry standard. Many techniques are used. This could generate conflicting data due to the variety of techniques, species of bacteria, incubation times and temperatures, and mediia used to evaluate both worn and unworn cntact lenses. Susceptability to bacterial attachment is of interesdt for extended wear lemses as are Dk/t and corneal swelling. Comments Dr.?

  4. That’s rather worrying news.

    I’m not personally affected, but I think it’s rather important that I trust the provider of my contact lenses…I have a hard enough time worrying about rats in the KFC!

    Thanks for the post.

    Eyes are an important part of our body that’s why we should take care of eyes. After a long time working our eyes need rest.

  6. That’s slightly worrying, but I suppose that with any manufactured products their are going to be anomalies.
