The aim of this paper was to assess soft contact lens replacement habits of patients of Contact Lens Clinic, Zagreb University Hospital Department of Ophthalmology, Zagreb, Croatia. During spring of 2010, a survey was conducted in Contact Lens Laboratory, Zagreb University Hospital Department of Ophthalmology, Zagreb, Croatia. 47 completed surveys were collected and analyzed. The results of the...

purpose: to compare rose-k and conventional rgp contact lenses in terms of visual acuity, visual function and comfort in keratoconus patients. method: fifty-four patients with keratoconus were randomly fitted with rose-k and conventional rgp contact lens (wohlk contact lens), by one experienced ophthalmologist using a standard (three touch point) approach. general and demographic information, k...

introduction: microbial keratitis is an infective process of the cornea with a potentially and serious visual impairments. contact lenses are a major cause of microbial keratitis in the developed countries especially among young people. therefore, the purpose of the present study was to evaluate the frequency and microbiological characteristic of clk in patients referred to the emergency depart...

We describe a wink-controlled hands-free switching system for eye-borne telescopic vision, based on a previously tested fixed-magnification telescope embedded within scleral contact lenses. Here we integrate orthogonal polarizers into the contact lens covering the F/9.1 refractive 1× and F/9.6 catadioptric 2.8× vision paths, to allow switching via external liquid crystal shutters. We provide ha...

BACKGROUND To investigate the antibiofilm efficacy of nitric oxide (NO) on soft contact lenses. METHODS Nitrite (NO precursor) release from various concentrations (0-1000 μM) of sodium nitrite (NaNO2, NO donor) was measured by Griess Assay. Cell viability assay was performed using human corneal epithelial cell under various concentration (0-1000 μM) of NaNO2. Biofilm formation on soft contact...
