The Canadian Ministry of Health announced on Monday the recall of several types of contact lenses due to an "isolated quality issue."

The problem was related to an external solvent used in manufacturing, according to a government notice regarding Total1 and Total30 lenses. A substance found within this solvent was detected in the final lenses, leading to the recall.

A complete list of the affected products can be found on the website.

Various models of Dailies Total1 One-Day Contact Lenses For Astigmatism, Delefilcon A Soft Contact Lenses Delefilcon A multifocal lenses, and Total30 (Lehfilcon A) Soft Contact Lenses are included in the recall.

"As a result, the specific batches may not meet Alcon's performance standards throughout their shelf life," the notice stated.

The issue was identified by Alcon Laboratories, the company responsible for the products, which is located in Texas.
