OTTAWA - CooperVision is expanding its recall of contact lenses after complaints of vision problems, discomfort and eye injuries related to the products.
Health Canada says in an advisory Wednesday that it is working with the company to identify which lenses on the Canadian market are affected by the worldwide recall.
CooperVision is pulling certain lots of its Encore100 Toric and Encore100 sphere contact lenses due to the presence of silicone oil on the products, which may cause hazy vision or discomfort, severe eye pain or eye injuries requiring medical treatment.
The residue was reportedly caused by a manufacturing problem experienced by CooperVision, one of the largest eye-care companies in the U.S.
The company advises consumers to stop wearing affected lenses immediately and contact their eye-care practitioner for advice.
Health Canada says CooperVision has taken action to correct the problem, and consumers and retailers should contact the company directly at 1-855-526-6737 for more information.
Consumers can fill out an online form at: www.coopervision.com/international-recall/ca/en to determine if they have an affected lot number.
Wednesday's recall notice is the company's third in recent months. In October, CooperVision recalled about 600,000 Avaira Toric contact lenses linked to pain, red eye and blurred vision in wearers after coming under pressure from U.S. health regulators. The company announced its first recall August 19.
In Canada, Avaira Toric lenses are sold as Encore Toric.
