Aspheric Intraocular Lenses
With continued improvements in surgical techniques, biometry, and intraocular lens (IOL) technology, cataract surgeons have for some time been capable of consistently achieving highly accurate quantitative refractive results following cataract/lens replacement surgery. We know we can improve an individual’s vision from 20/400 to 20/20, for example. The modern cataract surgeon, however, is now e...
متن کاملIntraocular lens calculation for aspheric intraocular lenses.
PURPOSE To evaluate the possible benefits of biometry and ray-tracing intraocular lens (IOL) calculation for aspheric aberration-correcting IOLs. SETTING Private eye clinic in Germany. DESIGN Retrospective consecutive case series. METHODS Eyes with 3 different aberration-correcting IOLs were reviewed. Before surgery, the axial length, corneal thickness, anterior chamber depth, crystalline...
متن کاملDesign of isoplanatic aspheric monofocal intraocular lenses.
A new and complete methodology of monofocal intraocular lens (IOL) design is presented aiming at isoplanatism, i.e. IOLs that provide the eye with optimized optical quality over a wide field of view (typically in a range of ten degrees). The methodology uses a merit function considering dimensional and biomechanical constraints, and a geometrical optical quality metric that is evaluated simulta...
متن کاملAspheric versus Spherical Posterior Chamber Intraocular Lenses
PURPOSE To compare spherical aberration and contrast sensitivity function following implantation of four different foldable posterior chamber intraocular lenses (IOLs), namely Sensar, Akreos AO, Tecnis, and AcrySof IQ. METHODS In this randomized clinical trial, 68 eyes of 68 patients with senile cataracts underwent phacoemulsification and IOL implantation with Sensar (n=17), Akreos AO (n=17),...
متن کاملAspheric Intraocular Lenses Implantation for Cataract Patients with Extreme Myopia
Objective. To evaluate the postoperative visual quality of cataract patients with extreme myopia after implantation of aspheric intraocular lenses (IOLs). Methods. Thirty-three eyes were enrolled in this prospectivestudy. Eighteen eyes with an axial length longer than 28 mm were included in the extreme myopia group, and the other 15 eyes were included in the nonextreme myopia group. Phacoemulsi...
