CooperVision toric contact lens recalled

Toric contact lens maker CooperVision is reminding customers about a recall of certain lots of lens that it says may cause temporary hazy vision and discomfort.

This summer, Costco Canada notified customers of a voluntary recall of certain Encore 100 Toric lenses purchased between April 18 and August 23.

On Wednesday, CooperVision said it is continuing to work with regulators, distributors, customers, eye care practitioners and lens wearers to complete the recall on certain lots of Avaira Toric contact lenses, which were sold in the U.S. and online.

"If you wear Avaira Toric contact lenses and experience any symptoms, CooperVision recommends that you stop wearing the lenses immediately," the company said in a statement. "Contact your eye care practitioner for advice."

For people who wear the lenses and are not experiencing symptoms, the company recommends:

Go to the CooperVision recall web page and enter the lot number of your package to determine whether your lenses have been recalled.

Alternatively, call the toll-free consumer hotline (1-855-526-6737)

If your lenses have been recalled, return your lenses to your eye care practitioner or point of purchase.

The recall was started because certain lots contained a residue that the company said can cause temporary hazy vision and discomfort.

"Not everyone experiences the same symptoms," CooperVision said. "Since the initiation of the recall the company has received some additional complaints of severe eye pain. Avaira Toric contact lens wearers that experience any symptoms should stop wearing the lenses immediately and speak with their eye care practitioner."

So far, the recall has affected about 600,000 Avaira Toric contact lenses in the U.S.

Distributors have been asked to send back all Avaira Toric products, not just specific lot numbers, so the company could ensure that affected lenses were removed.

The product is not listed in Health Canada's database of recalled products.
