The primary objective of this study is to identify how many focal points and at which distances are necessary for reliable visual curve formation and area of the curve (AoC) calculation using mathematical models and comparing the results to measurements acquired from participants that underwent uncomplicated pseudophakic presbyopia surgery.
This is a prospective, non-inferiority trial. 80 participants that underwent uncomplicated pseudophakic presbyopia surgery with bilateral premium intraocular lenses (IOL) implantation will be recruited, and their postoperative Visual Curves (VAC) will be evaluated for nine distances (25, 28, 33, 40, 50, 60, 100, 200, 300 cm). Then, using polynomial and spline interpolation methods on the measured data, the aim is to generate a unique polynomial of degree ninc -1 that satisfies all data points.
