The three-dimensional finite element model of the postoperative whole human eye after small incision lenticule extraction (SMILE) surgery and axisymmetric air-puff were established, influencing factors in Air-puff test explored from displacement nephogram on anterior corneal surface. Our results showed that maximum depression was positively correlated with corrected diopter when peak pressure e...

PURPOSE We investigated effects of pupil shifts, occurring with changes in luminance and accommodation stimuli, on refraction components and higher-order aberrations. METHODS Participants were young and older groups (n = 20; 22 ± 2 years; age range, 18-25 years; and n = 19, 49 ± 4 years, 45-58 years, respectively). Aberrations/refractions at 4- and 3-mm diameters were compared between centere...
