The role of sensory ocular dominance on through-focus visual performance in monovision presbyopia corrections.

摘要: Monovision presbyopia interventions exploit the binocular nature of visual system by independently manipulating optical properties two eyes. It is unclear, however, how individual variations in ocular dominance affect function monovision corrections. Here, we examined impact sensory on performance both traditional and modified presbyopic We recently developed a adaptive optics vision simulator to correct subjects' native aberrations induce either (1.5 D anisometropia, spherical aberration +0.1 −0.4 μm distance near eyes, respectively, over 4 mm pupils) or (1.5 D anisometropia). To quantify sign degree dominance, utilized rivalry estimate stimulus contrast ratios that yield balanced durations for Through-focus acuity sensitivity were measured under conditions: (a) assigning dominant nondominant eye near, (b) vice versa. The results revealed through-focus was unaffected dominance. Contrast sensitivity, significantly improved when coincided with superior quality. hypothesize potential mechanism behind this observation an interaction between summation, thus, assignment may be important factor optimize threshold at different object distances monovision.
