Spherical Aberration of Intraocular Lenses
Advancements in cataract surgery and intraocular lens (IOL) design have optimized the postoperative optical performance of the pseudophakic eye. One of the recent spotlights of IOL design has been formulating optical properties similar to a clear, young lens and addressing spherical aberration. Spherical aberration in the human eye is a combination of the positive spherical aberration of the co...
متن کاملIn vitro strehl ratios with spherical, aberration-free, average, and customized spherical aberration-correcting intraocular lenses.
PURPOSE To determine in vitro image qualities of artificial eyes achieved with spherical, aberration-free, average spherical aberration-correcting, and customized spherical aberration-correcting IOLs in centered, decentered, and tilted positions. METHODS The in vitro performance of these IOL models was determined by optical bench measurements. The experimental setup included a laser light sou...
متن کاملAdaptive optics simulation of intraocular lenses with modified spherical aberration.
PURPOSE Adaptive optics systems can be used to investigate the potential visual benefit associated with correcting ocular wave-front aberration. In this study, adaptive optics techniques were used to evaluate the potential advantages and disadvantages associated with intraocular lenses (IOLs) with modified spherical aberration profiles. METHODS An adaptive optics vision simulator was construc...
متن کاملExtended depth of focus with induced spherical aberration in light-adjustable intraocular lenses.
PURPOSE To evaluate the quality of vision and depth of focus induced by controlled amounts of negative spherical aberration in patients implanted bilaterally with light-adjustable intraocular lenses. DESIGN Prospective, nonrandomized clinical trial. METHODS Seventeen patients were implanted and treated with appropriate spatial irradiance light profiles. One eye was set for emmetropia, and t...
متن کاملSpherical aberration in spatial and temporal transforming lenses of femtosecond laser pulses.
We study the influence of third-order spherical aberration on the group velocity dispersion and on the propagation time delay of a plane pulse that is focused by a thin lens. Applications in refractive-diffractive propagation time delay compensation systems and in Gaussian temporal-shaped pulses are analyzed.
