In 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 کاملSpherical 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 کاملPhase plates for wave-aberration compensation in the human eye.
We present a method for manufacturing phase plates to compensate for the wave aberration in the human eye. The wave aberration of the eye is measured in vivo by a new laser ray-tracing method and then compensated for by a phase plate placed in front of the eye. This plate is made from a gray-level single-mask photosculpture in photoresist. Two experiments were carried out, first with an artific...
متن کاملSpherical Aberration, Accommodation and Myopia
Myopia should not be considered a benign condition because of the potential risks of vision loss associated not only with high myopia but also with the procedures used to correct myopia. Results from animal studies demonstrating that emmetropization is an active rather than a passive process and the induction of myopic refractive errors with imposed hyperopic defocus underlie the hypothesis tha...
متن کاملHitachi’s Spherical Aberration Corrected STEM: HD-2700
INTRODUCTION AS VLSI (very large scale integration) technology evolves toward ever smaller features and multilayer designs, analysis and control of structures and compositions at the atomic level is becoming increasingly important. In 1998 Hitachi HighTechnologies Corporation released the HD-2000, a STEM (scanning transmission electron microscope) that was very well received for combining the e...
