"Femtosecond Laser Induced Refractive Index Change in Acrylic Polymers used to Create a Modification of the Optical Performance of an Existing Intraocular Lens"^^ . "A femtosecond laser-based hydrophilicity change was developed to alter the refractive index of acrylic polymeric materials. The combination of the precise modulation of the refractive index change in magnitude and position allows the creation of a phase-wrapped, gradient lens inside an implanted intraocular lens (IOL).\r\nPreoperative, intraoperative and postoperative factors can impact the visual outcome of a patient after cataract surgery. About 25.7% of cataract patients have postoperative spherical error of more than 0.5D [1]. Additionally, 37.8% of cataract patients have a residual astigmatism of at least 1 D [2]. These considerations indicate that a large number of patients would benefit from a post cataract surgery adjustment method.\r\nThe refractive index shaping (RIS) process is designed to turn standard monofocal and multifocal IOLs into adjustable lenses which in theory could be modified multiple times to adjust the post-cataract patient’s vision without requiring invasive surgeries.\r\nAfter a lengthy optimization phase this procedure was successfully used to alter existing IOLs in-vitro and in-vivo in a rabbit model. Additional studies were performed to investigate and validate the effect of the process on IOL quality, light transmission and biocompatibility."^^ . "2019" . . . . . . . "Ruth"^^ . "Sahler"^^ .
