: Acanthamoeba keratitis has been increasing in recent years. Main risk factors are contact lens wear and their cleaning solutions. Most contact lens wearers use multipurpose disinfecting solutions (MPDS) for cleansing and disinfecting microorganisms because of its convenience. We determined amoebicidal effects of MPDS made in Korea and their cytotoxicity on human corneal epithelium cells. Fifteen commercial MPDS (A to O) were tested for their amoebicidal effects on Acanthamoeba castellanii trop...

ABSTRACTPurpose: In the present work, the effect of monomer composition on silver nanoparticles’ (SNPs) binding capacity of hydrogels was investigated and their antibacterial efficacy was evaluated.Materials and methods: Three series of poly-hydroxyethyl methacrylate (HEMA) hydrogels were prepared using methacrylic acid (MAA), methacrylamide (MAAM), and 4-vinylpyridine (4VP) as co-monomers, and ethylene glycol dimethacrylate (EGDMA) as cross-linker. SNPs binding capacity of hydrogels was evaluat...

Abstract To evaluate adhesion of Acanthamoeba trophozoites to different silicone hydrogel contact lens (SHCL) generations with and without multipurpose contact lens care solution (MPS) treatment. Acanthamoeba lugdunensis L3a trophozoites were inoculated onto discs trimmed from SHCLs: first generation, Air Optix (Lotrafilcon B) with a plasma surface treatment, second generation, Acuvue Oasys (Senofilcon A), which contains an internal wetting agent (Hydraclear), and third generation, Biofinity (Co...

Purpose To evaluate the effect of multipurpose contact lens care solutions (MPSs) on the adhesion of Acanthamoeba to rigid gas permeable (RGP) contact lenses. Methods Acanthamoeba castellanii (AC) trophozoites were inoculated onto untreated RGP contact lenses (FP, Extra, or Menicon Z), and numbers of trophozoites adhering to lenses were counted under a phase contrast microscope at 18 h post-inoculation (controls). Similarly, adhering trophozoites were counted at 6 h post-inoculation on each of t...

PURPOSE: To describe the adhesion properties of Acanthamoeba castellanii trophozoites to silicone hydrogel contact lenses of first generation (lotrafilcon A), second generation (galyfilcon A), and third generation (comfilcon A) and correlate the results with their specific surface characteristics, time of interaction, and suspension media. METHODS: Qualitative and quantitative assessments of the adhesion of 200 trophozoites of A. castellanii on contact lenses in culture medium (Bacto Casitone) a...

PURPOSE: Silver-impregnated contact lens (CL) storage cases are designed to reduce microbial contamination during use, but there are limited data on their effectiveness. This study evaluated early antimicrobial activity of silver-impregnated CL cases and silver-release characteristics in vitro. METHODS: Three silver-impregnated CL storage cases-MicroBlock (CIBA Vision, Atlanta, GA), i-clean (Sauflon Pharmaceuticals Ltd., London, UK), and Nano-case (Marietta Vision, Marietta, GA)-were evaluated. ...

PURPOSE: We evaluated (1) 4 multipurpose lens care solutions and 3 contact lenses (soft and rigid) for cytotoxicity according to ISO 10993-5 standard (medical device biocompatibility) and (2) the protective effects of a marine cationic solution and hyaluronic acid. METHODS: Low water soft lens, high water soft lens, and rigid lens were laid on a conjunctival cell line after being soaked in multipurpose solution (Optifree Express, Renu, Solocare Aqua, or Menicare Plus). Cell morphology was micros...

Purpose. This study was designed to qualitatively and quantitatively characterize the surface morphology of four unworn conventional hydrogel contact lenses (omafilcon, hioxifilcon, nelfilcon A, and ocufilcon B) and two silicone-hydrogel contact lenses (senofilcon A and comfilcon A) without surface treatment. Methods. Surface roughness was assessed using atomic force microscopy in Tapping Mode TM to determine the representative roughness parameters mean surface roughness (Ra), mean square roughn...

Aims to determine if plasma surface treatment of Focus Night & Day silicone hydrogel contact lenses affects the attachment of Acanthamoeba. Unworn lotrafilcon A contact lenses with (Focus Night & Day) and with out surface treatment and Acuvue, conventional hydrogel lenses were quartered prior to 90 minutes incubation with Acanthamoeba castellanii trophozoites. After incubation and rinsing the trophozoites attached to one surface of each quarter were counted by direct light microscopy. Sixteen re...

Acanthamoebae are free-living amoebae found in the environment, including soil, freshwater, brackish water, seawater, hot tubs, and Jacuzzis. Acanthamoeba species can cause keratitis, a painful vision-threatening infection of the cornea, and fatal granulomatous encephalitis in humans. More than 20 species of Acanthamoeba belonging to morphological groups I, II, and III distributed in 15 genotypes have been described. Among these, Acanthamoeba castellanii, A. polyphaga, and A. hatchetti are frequ...
