Light-adjustable lens.
PURPOSE First, to determine whether a silicone light-adjustable intraocular lens (IOL) can be fabricated and adjusted precisely with a light delivery device (LDD). Second, to determine the biocompatibility of an adjustable IOL and whether the lens can be adjusted precisely in vivo. METHODS After fabrication of a light-adjustable silicone formulation, IOLs were made and tested in vitro for cyt...
متن کاملA numerical model of light adjustable lens
We model numerically the mechanical effects of UV induced photo-polymerization in elastomeric artificial lens. The elastomer is originated upon cross-linking of a silicone matrix. UV irradiation of one side of the lens polymerizes selectively a photosensitive macromer, causing local variations of its concentration. The subsequent diffusion of macromers from high concentration to low concentrati...
متن کاملAdjustable hybrid diffractive/refractive achromatic lens
We demonstrate a variable focal length achromatic lens that consists of a flat liquid crystal diffractive lens and a pressure-controlled fluidic refractive lens. The diffractive lens is composed of a flat binary Fresnel zone structure and a thin liquid crystal layer, producing high efficiency and millisecond switching times while applying a low ac voltage input. The focusing power of the diffra...
متن کاملLight-adjustable lens: customizing correction for multifocality and higher-order aberrations.
PURPOSE To determine the feasibility of creating customized multifocal and aspheric patterns onto a light-adjustable lens (LAL) using a digital light delivery (DLD) system. METHODS Silicone LALs were placed in a wet cell and irradiated in vitro using the DLD. Spatial intensity patterns were designed and generated to (1) create a multifocal optic with customized power and diameter and (2) simu...
متن کاملA cylindrical zoom lens unit for adjustable optical sectioning in light sheet microscopy
Light sheet microscopy became a powerful tool in life sciences. Often, however, the sheet geometry is fixed, whereas it would be advantageous to adjust the sheet geometry to specimens of different dimensions. Therefore we developed an afocal cylindrical zoom lens system comprising only 5 lenses and a total system length of less than 160 mm. Two movable optical elements were directly coupled, so...
