Presbyopia: Effectiveness of correction strategies
TL;DR: A redefinition of presbyopia is proposed that states “presbyopia occurs when the physiologically normal age‐related reduction in the eye's focusing range reaches a point, when optimally corrected for distance vision, that the clarity of vision at near is insufficient to satisfy an individual's requirements”.

Optical Evaluation of New Designs of Multifocal Diffractive Corneal Inlays
TL;DR: Improvements in imaging of near objects and in light throughput compared with the popular small aperture inlays were demonstrated and open a new technical branch of minimally invasive surgical solutions for the treatment of presbyopia.
Journal ArticleDOI
The Effect of Age, Accommodation, and Refractive Error on the Adult Human Eye.
TL;DR: Refractive error is significantly correlated with not only the axial dimensions but also the anterior equatorial dimension of the adult eye and further testing and development of accommodating intraocular lenses should account for differences in patients’ preoperative refractive error.
Journal ArticleDOI
Comparison of clinical performance between trifocal and bifocal intraocular lenses: A meta-analysis.
TL;DR: Trifocal IOL technology (especially AT Lisa trifocal 839M trif focal) had a clear advantage over bifocalIOLs in intermediate visual acuity, while both trifoc IOLs and bifocals showed excellent performance in distanceVisual acuity.
Journal ArticleDOI
Stimulus-driven Versus Pilocarpine-induced Biometric Changes in Pseudophakic Eyes: Author Reply
TL;DR: Pilocarpine may act as a superstimulus and may not adequately simulate daily life performance of accommodative IOLs, however, it may be helpful to evaluate the maximum potential of an accommodating IOL.

Mechanisms of femtosecond laser nanosurgery of cells and tissues
TL;DR: In this article, the working mechanisms of femtosecond laser nanoprocessing in biomaterials with oscillator pulses of 80-MHz repetition rate and with amplified pulses of 1-kHz repetition rate were investigated.
Journal ArticleDOI
Excimer Laser Surgery of the Cornea
TL;DR: Applying the far-ultraviolet light in short intense pulses permitted us to control the depth of the incision with great precision and it was found that 1 joule/cm2 ablates corneal tissue to a depth of 1 micron.
Journal ArticleDOI
Results of small incision lenticule extraction: All-in-one femtosecond laser refractive surgery
TL;DR: All‐in‐one femtosecond refractive correction using a small incision technique was safe, predictable, and effective in treating myopia and myopic astigmatism.
Journal ArticleDOI
Accommodation-dependent model of the human eye with aspherics
TL;DR: The average spherical aberration of the actual eye is predicted without any shape fitting by introducing recent experimental average measurements of cornea and lens into the Gullstrand-Le Grand model.
Journal ArticleDOI
Biometric, optical and physical changes in the isolated human crystalline lens with age in relation to presbyopia.
TL;DR: The studies reinforce the conclusion that lens hardening must be considered as an important factor in the development of presbyopia, that age changes in the human lens are not limited to the loss of accommodation that characterizes Presbyopia but that the lens optical and physical properties change substantially with age in a complex manner.
