A doublet intraocular lens optimized for both chromatic and monochromatic aberration correction in pseudophakic eyes is presented. Ray-tracing techniques were applied to design the lens in white light within a chromatic eye model. Combinations of two materials, already commonly used in intraocular lenses, as acrylic and silicone, were used. Iterative optimization algorithms were employed to correct for longitudinal chromatic aberration, spherical aberration and off-axis aberrations within 10…

Design and Evaluation of Refractive Multifocal Intraocular Lenses Implanted within the Human Eye

In this paper, optimum design of three classic model have been proposed, for refractive multifocal intraocular lenses (singlet, doublet, triplet-MIOLs) implanted within human eye (Liou & Brennan

Impact of longitudinal chromatic aberration on through-focus visual acuity.

Low capability of the model to predict VA in modified LCA conditions suggests that neural adaptation may play a role in how LCA manipulation affects the depth of focus.

On the Chromatic Dispersion of Hydrophobic and Hydrophilic Intraocular Lenses

The hydrophobic materials showed larger dispersion than did the hydrophilic IOL materials resulting in increased chromatic aberration.

Adaptation to the eye's chromatic aberration measured with an adaptive optics visual simulator.

The results suggest that some LCA neural adaptation may exist, particularly for low contrast VA, which impacts the performance of vision under corrected LCA, and possibly prevents measurement for immediate visual benefit.

Compositional Optimization of Chalcogenide Glasses for Use as Imaging Lenses in the Long-Wavelength Infrared Range

Demand on thermal camera capable of visualizing spatial distribution of infrared radiation especially in the long-wavelength infrared (LWIR; 8-12 μm) range is rapidly increasing in diverse civilian

The characteristics of the next generation of IOL materials must satisfy biocompatibility requirements and have tuneable refractive index to create patient-specific eye power, preventing formation of posterior capsular opacification are investigated.

Full-visible achromatic imaging with a single dual-pinhole-coded diffractive photon sieve.

The proposed and experimentally demonstrate an achromatic imaging in the full-visible wavelength range with a single dual-pinhole-coded diffractive photon sieve (PS) and provides a novel and practical way for achieving a chromatic imaging within the full visible range with features of thin, light and planar.

Extended Depth-of-Field Intraocular Lenses

Extended depth-of-focus (EDOF) optical profiles are a new optical design that is currently considered as an attractive alternative to accommodative and multifocal intraocular lenses (IOLs). Currently

Keratoconic eyes with stable corneal tomography could benefit more from custom intraocular lens design than normal eyes

Custom freeform IOL-optics-design may become a promising option for the correction of advanced aberrations in eyes with non-progressive keratoconic corneal tomography pattern.



Adaptive optics simulation of intraocular lenses with modified spherical aberration.

Correcting ocular spherical aberration improves spatial vision in the best-focus position without compromising the subjective tolerance to defocus.

Theoretical performance of intraocular lenses correcting both spherical and chromatic aberration.

This is the first study that evaluates IOLs correcting both LSA and LCA in the presence of corneal higher order aberrations, showing the potential to improve visual performance.

Binocular visual acuity for the correction of spherical aberration in polychromatic and monochromatic light.

Bilateral correction of both SA and LCA may further improve binocular spatial visual acuity which may support the use of aspheric-achromatic ophthalmic devices, in particular, intraocular lenses (IOLs).

Visual effect of the combined correction of spherical and longitudinal chromatic aberrations.

The visual improvement provided by the correction of SA was higher than that from correcting LCA, while the combined correction of LCA and SA provided the best visual performance, suggesting that an aspheric achromatic IOL may provide some visual benefit when compared to standard IOLs.

Compensation of corneal aberrations by the internal optics in the human eye.

The amount of aberration of both the cornea and internal optics was found to be larger than for the complete eye, indicating that the first surface of the corneal topography and the internal ocular optics partially compensate for each other's aberrations and produce an improved retinal image.

Retinal image contrast obtained by a model eye with combined correction of chromatic and spherical aberrations

The contrast improvement from the SA correction was higher than the LCA correction, indicating the benefit of an aspheric achromatic IOL.

Predicting the optical performance of eyes implanted with IOLs to correct spherical aberration.

A "virtual surgery" approach was designed to predict the optical performance in pseudophakic eyes and the aberrations of implanted eyes predicted by the individualized optical models were well correlated with the actual aberration measured in each subject.

Accommodating intraocular lenses: a critical review of present and future concepts

Laser interferometry measures what shift lenses are designed to provide: axial shift on accommodative effort and magnet-driven active-shift lens systems carry the potential of sufficiently topping up apparent accommodation to provide for clinically useful accommodation while using conventional lens designs with proven after-cataract performance.

Halo and Through-Focus Performance of Four Diffractive Multifocal Intraocular Lenses.

Differences in the design of the diffractive IOLs translate into differences in optical quality at their foci, through-focus performance, and halo features, which can offer further information to surgeons when selecting which IOL to implant.
