(WENY) -- Severe eye infections nationwide are linked to eye drops manufactured by Global Pharma Healthcare. With the artificial tears being sold under multiple brand names, Global Pharma has issued a recall following 68 reports of infections, eight people losing their vision, and three deaths linked to the drops. 

“I think some people might've bought these drops online,” Guthrie’s Dr. Jonathan Manhard, M.D., said, adding, “Some people were even found to have gotten these at Costco, surprisingly enough.”   

The eye drops are contaminated by a bacteria called Pseudomonas aeruginosa. While the source of the contamination is still under investigation, it's suspected that opened containers could be one reason.  

“I would be extra careful to make sure that that bottle looks like it's in good shape and is a relatively recent purchase,” Dr. Manhard said, adding, “I wouldn't use something that's six months old.”  

Dr. Manhard says if you have eye drops at home, you're going to want to check the label. He urges people to be aware of the brands recalling their eye drops.  

“I think (making) sure it doesn't say Ezricare or Delsam Pharmaceutical artificial tears on it would be a (smart) thing to do at this time.” Dr. Manhard said.  

For people who rely on artificial tears, Dr. Manhard believes common eye drops sold at local pharmacies are safe. He says products like GenTeal are one alternative not manufactured by Global Pharma.  

“The common manufacturers are well vetted,” Dr. Manhard said, adding, “There have been no cases of this sort of thing happening recently with those common artificial tears.”  

Dr. Manhard shares what early warning signs for these types of eye infections look like. He says if eye drop users start experiencing discharge, redness, and worsening eyesight over time, they should get it checked out at their local ophthalmologist.
