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 کاملPredicting the optical performance of eyes implanted with IOLs to correct spherical aberration.
PURPOSE To use powerful modeling techniques for predicting the optical performance of eyes implanted with different types of intraocular lenses (IOLs). This approach will allow performance of "virtual cataract surgery," with different IOL designs that can be used and physical parameters that may occur during actual surgery-in particular, in IOLs that correct spherical aberration. METHODS A 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...

Introduction: With the growing and rapid development of refractive surgery, researches focus increasingly on improvement of visual quality after cataract surgery. Intraocular lenses (IOLs) were a successful effort in the field of cataract surgery. Despite significant advances in cataract surgery, several complications related to surgical technique and IOL design after surgery can cause vision c...
متن کاملA new intraocular lens design to reduce spherical aberration of pseudophakic eyes.
PURPOSE The aim of this study was to design and evaluate in the laboratory a new intraocular lens (IOL) intended to provide superior ocular optical quality by reducing spherical aberration. METHODS Corneal topography measurements were performed on 71 cataract patients using an Orbscan I. The measured corneal surface shapes were used to determine the wavefront aberration of each cornea. A mode...
