Status of the effectiveness of contact lens disinfectants in Malaysia against keratitis-causing pathogens [PDF]

open access: yes, 2017
The aim of this study was (i) to assess the antimicrobial effects of contact lens disinfecting solutions marketed in Malaysia against common bacterial eye pathogens and as well as eye parasite, Acanthamoeba castellanii, and (ii) to determine whether ...

Orbifold adjunction formula and symplectic cobordisms between lens spaces

open access: yes, 2004
Each lens space has a canonical contact structure which lifts to the distribution of complex lines on the three-sphere. In this paper, we show that a symplectic homology cobordism between two lens spaces, which is given with the canonical contact ...

Fabrication of Miniaturized Variable-focus Lens Using Liquid Filling Technique [PDF]

open access: yes, 2007
This paper describes a simple method for fabricating a variable-focus lens by using PDMS (polydimethylsiloxane) and filling with liquid for the variable-focus lens. The lens diameter of 2-mm was designed in this experiment and expected to reach the focal

Bilateral Acanthamoeba keratitis [PDF]

open access: yes, 2012
Acanthamoeba keratitis is a rare eye infection commonly misdiagnosed as herpes simplex or fungal keratitis. Failure to include it in the differential diagnosis in any contact lens wearer with the typical features of an eye infection, results in a ...

The pathogenesis of Acanthamoeba infections: current status and future implications [PDF]

open access: yes, 2004
Acanthamoeba are opportunistic protozoan parasites that can cause painful, visionthreatening keratitis. However the pathogenesis and pathophysiology of Acanthamoeba keratitis remain incompletely understood. Most cases of Acanthamoeba keratitis develop

Conceptual aspects of line tensions

open access: yes, 2007
We analyze two representative systems containing a three-phase-contact line: a liquid lens at a fluid--fluid interface and a liquid drop in contact with a gas phase residing on a solid substrate.

Stretchable electronic platform for soft and smart contact lens applications [PDF]

open access: yes, 2017
A stretchable platform with spherical-shaped electronics based on thermo- plastic polyurethane (TPU) is introduced for soft smart contact lenses. The low glass transition temperature of TPU, its relatively low hardness, and its proven biocompatibility (
