purpose: to determine the sensitivity and specificity of confocal scan in the diagnosis of fungal and acanthamoeba keratitis based on the results of corneal and/or contact lens case smear and culture. method: confocal scan and corneal and/or contact lens case smear and culture were performed in all patients with a clinical diagnosis of infectious keratitis who were referred to labbafinejad medi...

PURPOSE Deprivation of oxygen to the ocular surface during contact lens wear has been implicated in the alteration of sensory function. This study investigates whether increasing oxygen availability through discontinuation of contact lens wear or transfer into highly oxygen transmissible (high Dk/t) lenses leads to a change in corneal or conjunctival sensitivity. METHODS Twenty-seven long-ter...

Contact lenses are a successful form of vision correction. But their use has been associated with an increased risk of microbial keratitis (MK), contact lens related acute red eye (CLARE) as well as contact lens peripheral ulcer (CLPU) (Eltis, 2011). One of the main problems associated with contact lenses is microbial contamination of the lens surface. Microbial contamination further leads to t...

Brane world cosmologies seem to provide an alternative explanation for the present accelerated stage of the Universe with no need to invoke either a cosmological constant or an exotic quintessence component. In this paper we investigate statistical properties of gravitational lenses for some particular scenarios based on this large scale modification of gravity. We show that a large class of su...

PURPOSE To understand the potential barriers, motivators and enablers in dispensing multifocal contact lenses (MFCL). METHOD Two focus group discussions were conducted to design questionnaires regarding the prescribing habits for multifocal contact lenses (MFCL). Questions on potential barriers and motivators were included. The questionnaires were distributed among 133 eye care practitioners ...
