These microorganisms, which include bacteria in addition to fungi, produce compounds that form a slimy matrix, which assists the microbes stick to each other and to the lens surface area and makes them more resistant to the decontaminating action of contact lens options.

Fungal Infections Associated With ReNu Contact Lens Solution

Often, contact lens-related fungal eye infections can be triggered by issues with contact lens solutions.

In 2006, a significant fungal eye infection break out occurred in the United States. Inning accordance with the U.S. Centers for Disease Control and Prevention (CDC):

  • 154 cases of fungal keratitis were confirmed from June 2005 through June 2006 in 33 states.
  • 94 percent of these cases were amongst people wearing soft contact lenses.

Prior to the break out in America, similar cases of fungal keratitis associated with ReNu with MoistureLoc were documented in Malaysia, Singapore and Hong Kong from late 2005 to early 2006. Fungal eye infections associated with use of the contact lens disinfecting item likewise were found in Europe in 2006.

In May 2006, Bausch + Lomb (Rochester, N.Y.) willingly withdrew ReNu With MoistureLoc items from worldwide markets while examinations of the infections associated with the item continued.

Private investigators figured out that all of the cases of fungal eye infections seemed connected to ReNu With MoitureLoc that was produced at Bausch + Lomb’s Greenville, S.C., producing facility. However the CDC discovered no fungal contamination of unopened bottles of the contact lens solution produced at the plant.

In June 2009, news reports showed that Bausch + Lomb had settled about 600 suits associated to the break out of fungal eye infections connected with the contact lens solution and paid roughly $250 million in settlements.

Break outs Of Eye Infections Lead To Call For Higher Standards

    I likewise attempted the ReNu with moisture lock. A week after utilizing the item, i started having issues. The contacts would be o.k. for about an hour into wearing them and after that i would start feeling a burning experience. For me it was unusual since the truly bad inflammation was only in my right eye. Following the burning feeling, my eye would start to water and REALLY start to burn. I would take that contact out and go “one eyed” for the rest of my work day. I lastly had adequate and went to see my eye doctor. He examined my eye and stated that they looked hazey and that the capillary in my eye and eye lids were actually red and inflamed. I informed him I switched solutions and he told me to stop wearing my contacts for a week, put medication drops he provided me into my eye, then when i started to use them once again, return to my initial service. After the week I put my contacts back in and the exact same thing began occurring. The burning, itching, and wateryness was still there. I went to a professional and he believed it was allergic reactions to my cats.(I’ve had my cats for 3 years with no problems!) He even went so far as to change my brand of contacts but to no get. After about a month, all the symptoms disappeared.
