This investigation examines the effectiveness of several common contact lens solutions in the disinfection of Acanthamoeba, which causes a serious eye infection most often resulting from dysfunctional or improper use of contact lens products.
PURPOSE
Acanthamoeba keratitis is an eye infection caused by a free-living amoeba, which can lead to extensive corneal damage and frequently blindness. Acanthamoeba keratitis is linked with contact lens use combined with noncompliance with contact lens care cleaning regimens. The patient's choice and use of multipurpose solutions (MPSs) continue to be a risk factor for Acanthamoeba keratitis. Thus, it is critical that the Acanthamoeba disinfection efficacy of the popular MPSs be determined. Here we compare the efficacy of seven major MPSs on the global market.
METHODS
Using standard methods of Acanthamoeba disinfection and quantification, Acanthamoeba ATCC 30461, 30868, 50370, and 50676 trophozoites were inoculated into each MPS and held for the manufacturer's recommended disinfection time. Acanthamoeba recovery plates were incubated for 14 days, after which positive wells were identified and cell concentrations determined using the 50% endpoint method.
RESULTS
Members of the OPTI-FREE products (Express, Replenish, and Puremoist [Alcon, Fort Worth, TX]) demonstrated significantly higher percentages of antimicrobial activity compared with the renu Advanced Formula (Bausch + Lomb, Rochester, NY), Biotrue (Bausch + Lomb), Acuvue RevitaLens (Johnson & Johnson, Santa Ana, CA), and Lite products (Cooper Vision, Scottsville, NY) for four of the trophozoite strains tested.
CONCLUSIONS
Many of the popular MPS biocides maintain little or no antimicrobial activity against Acanthamoeba trophozoites, and the number of biocides in an MPS does not necessarily indicate its antimicrobial activity.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus HELB]:Paramédical:MédicamentsRésumé : drug delivery in scleral lens wear is still a bit uncharted territory, althougt talk about this and pioneering work in the field date back at least a few decades. The areas of potential application could be prevention against corneal infection in case of corneal defect, and particulary in case of persistent epithelial defect healing. These defect can be very difficult to re-epitheliaze, and it is important to use prophylactic antibiotics, to prevent corneal infection in these vulnerable eyes. Another area of potential application could be the use of medication that prevents neovascularisation in the cornea.These drug can prevent new blood vessel growth in the cornea. Other areas such as glaucoma medication application are still under investigation. here, like in general scleral lens fitting, it is the balance between the benefits and the costs (including risks etc..) that need to be considered. here is an overview of what we know so far.

[Thésaurus HELB]:Optique:lentilles scléralesRésumé : Scleral lenses, hybrid or ortho-k to ensure safe use of these types of contact lenses, the main focus is on the oxygen permeability of the plastic material of the lens. The metabolism of the cornea and the limbus should suffer as little irritation as possible. The aim of this article is to explain how this transport mechanism occurs and why it is so important.
