The primary objective of this study is to evaluate postoperative visual acuity curves in pseudophakic patients following unilateral or bilateral implantation of the enhanced monofocal TECNIS Eyhance IOL, using the DDARTVC.
The present study aims to identify the exact points of the visual acuity curve, in which the enhanced monofocal TECNIS Eyhance IOL exhibit the optimal visual performance. Specifically, the study takes into account that the validated digital acuity chart DDARTVC assesses visual acuity under real-life conditions at nine discrete distances (25, 28, 33, 40, 50, 60, 100, 200, and 300 cm), rather than through simulated defocus values. Moreover, spline curve fitting was applied to the measured data points to generate continuous visual acuity curves, enabling estimation of visual performance across the full range of distances, rather than only at the predefined measurement points.
