introduction: quality of services extremely depends on how personnel have contact and interaction with the clients. moreover, the personnel’s attitudes and their behaviors with the clients significantly affect clients’ perception of quality of services and consequently influence their satisfaction as well as their absorption to the services of an institution. this study intends to investigate t...

PURPOSE To explore patient demographics and motivations in choosing refractive surgery (RS) or contact lenses (CL) and factors influencing their choice of practice. METHODS A questionnaire was presented to 212 RS and 115 CL patients at four RS centres and three CL centres, respectively. The authors, with consent from the clinics and patients, collected all data. No patient or clinic refused t...

The cornea is the main refractive surface of the eye. The prolate shape of the cornea plays a role in maintaining the optimum total spherical aberration (SA) of the eye by neutralizing the negative SA of the lens. As we age the lenticular SA shifts in the positive direction while the corneal SA remains the same, making the total ocular SA more positive. SA of the eye is directly proportional to...

Choosing a camera for use in the dermatology office is difficult, particularly in the case of a digital camera because the market is constantly evolving. This article explains the features that should be taken into account, including camera type, sensor, lens and macro capability, aperture priority mode, screen, viewfinder, operating speed, flash, battery, memory card, and image format. The mos...

Purpose of review: The purpose of this review is to contribute to the Choosing Wisely Canada campaign and develop a list of 5 items for nephrology health care professionals and patients to re-evaluate based on evidence that they are overused or misused. Sources of information: A working group was formed from the Canadian Society of Nephrology (CSN) Clinical Practice Guidelines Committee. This w...

Actions that are chosen have properties that distinguish them from actions that are not. Of the nearly infinite possible actions that can achieve any given task, many of the unchosen actions are irrelevant, incorrect, or inappropriate. Others are relevant, correct, or appropriate but are disfavored for other reasons. Our research focuses on the question of what distinguishes actions that are ch...

purpose: to report clinical outcomes of crystalline lens extraction and iris claw artisan intraocular lens (iol) implantation in patients with lens subluxation secondary to marfan syndrome.  methods: this retrospective study enrolled 14 eyes of 12 marfan patients with lens subluxation who underwent crystalline lens removal and artisan iol implantation. pre- and post-operative data, including pa...

It has been demonstrated previously that Pax-6, a paired domain (PD)/homeodomain (HD) transcription factor critical for eye development, contributes to the activation of the alphaB-, alphaA-, delta1-, and zeta-crystallin genes in the lens. Here we have examined the possibility that the inverse relationship between the expression of Pax-6 and beta-crystallin genes within the developing chicken l...

Choosing the appropriate type of video input is an important issue for any vision-based system and the right decision must take into account the specific requirements of the intended application. We present GlobeAll, a modular four-component prototype for a vision-based Intelligent Room: a panoramic video input component that uses an electronic pan-tilt-zoom camera array, a background learning ...
