Optical performance of a new design of trifocal intraocular lens based on the Devil's diffractive lens [PDF]

, 2023
In this work, we propose a new diffractive trifocal intraocular lens design with focus extension, conceived to provide a high visual performance at intermediate distances. This design is based on a fractal structure known as the "Devil's staircase".
