Overview
Brief Summary
This study was aimed to examine differences in binocular visual acuity and contrast sensitivity after implantation of continuous-focus IOLs (Synergy) with those with trifocal IOLs. Although the superiority in binocular visual acuities at 30 cm and 40 cm, and binocular contrast sensitivities at far, 1 m, and 40 cm were denied, clinical characteristic of subjective IOLs in uncorrected binocular visual acuity and symptoms of dysphotopsia were clarified.
