BACKGROUND Today, patients often expect to achieve spectacle independance after cataract surgery. New trifocal intraocular lenses have been developed to try and fullfill this demand. The purpose of this study is to report the short-term visual outcomes of a new trifocal intraocular lens (AcrySof PanOptix™). METHODS Consecutive adult patients undergoing cataract surgery with bilateral implanta...

PURPOSE To compare ocular performance and quality of vision in pseudophakic eyes with an aspherical intraocular lens (IOL) or a conventional spherical IOL. SETTING Bretonneau University Hospital, Tours, France. METHODS Twenty patients (40 eyes) were randomly divided in 2 equal groups to bilaterally receive the aspherical Tecnis Z9000 IOL (AMO) or the spherical CeeOn Edge 911 IOL (AMO). Cont...

Apart from the well-known loss of color vision and of foveal acuity that characterizes human rod-mediated vision, it has also been thought that night vision is very slow (taking up to 40 min) to adapt to changes in light levels. Even cone-mediated, daylight, vision has been thought to take 2 min to recover from light adaptation. Here, we show that most, though not all adaptation is rapid, takin...

PURPOSE To investigate the efficacy and predictability of wavefront-guided laser in situ keratomileusis (LASIK) treatments using the iris registration (IR) technology for the correction of refractive errors in patients with large pupils. SETTING Horus Vision Correction Center, Alexandria, Egypt. METHODS Prospective noncomparative study including a total of 52 eyes of 30 consecutive laser re...

PURPOSE The aim of the study is to evaluate the visual acuity and patient satisfaction at varied distances under photopic and mesopic lighting conditions in patients bilaterally implanted with aspheric diffractive multifocal one-piece intraocular lenses. METHODS In this retrospective-prospective study, 16 patients with a mean age of 66.2±9.2 years (range: 50-81 years) who had undergone bilate...

Judicious use of lamps is profound significance to improve the internal traffic safety tunnels. This study evaluated effect LED color on human visual fatigue under mesopic vision category. According difference eyes’ response different wavelengths light radiation, spectral luminous efficiency curve applied evaluation methods. Taking critical fusion frequency as physiological index, detection exp...

PURPOSE Driving is essentially a visuomotor task, and there is now compelling evidence that the disproportionate number of road accidents under night driving conditions is linked to changes in visual performance resulting from reduced lighting. The objective of this article is to establish the extent to which vision is either rod-or cone-dominated under night driving conditions. METHODS Visua...

BACKGROUND The purpose of this study was to record the visual outcomes of patients treated by six surgeons after implantation of a trifocal lens. METHODS The setting for this study comprised six ophthalmology units and eye clinics in Belgium and France, with a coordinating center in France, and data management and statistical analysis in France and Belgium. Ninety-four eyes from 47 patients w...
