Design 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 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 کاملAnalytical tools for customized design of monofocal intraocular lenses.
We propose a complete methodology to develop custom monofocal Intraocular Lens (IOL) designs and evaluate their performance on-axis based on an analytical formulation. The analytical formulation was based on Gaussian and primary aberration theory applied to custom (individual biometric data) and realistic (multilayer cornea and thick IOL) pseudoaphakic eye models. Gradient-based optimization al...
متن کاملComparisons of amplitude of pseudoaccommodation with aspheric yellow, spheric yellow, and spheric clear monofocal intraocular lenses
PURPOSE To determine the amplitude of pseudoaccommodation and higher-order aberrations with three types of implanted monofocal intraocular lenses (IOLs): aspheric yellow (IQ); spheric yellow (NT); and spheric clear (AT). SETTING Department of Ophthalmology, Nara Medical University, Nara, Japan. METHODS We studied 60 patients who underwent small incision phacoemulsification with the implanta...
