Functional Magnetic Resonance Imaging to Assess the Neurobehavioral Impact of Dysphotopsia with Multifocal Intraocular Lenses

“…33 Although there is insufficient consensus on the contribution of neuroadaptation to postsurgical care, there is wide consensus on the need to further understand the process, because neural adaptation to multifocality may vary among patients. 10 The first step to any treatment or effective medical preventive strategy is the knowledge of the disease pathophysiology. Until now, dysphotopsia has been addressed solely on the basis of studies of optic properties and questionnaires, and consequently, its neurobehavioral impact remains unclear.…”

“…4,6e8 There is a lack of effective treatments for these subjective symptoms, and thus patients may require IOL explantation in 0.3% to 12% of the cases. 4,6,9,10 Optical parameters per se do not explain these differences in outcomes because forward light scatter, higher-order aberrations, pupil diameter, and uncorrected visual acuity are similar in patients with and without dysphotic symptoms. 5,11 Even after excluding other causes for decreased quality of vision, such as dry eye, posterior capsule opacification, and retinal disease, there is still no identified correlation between subjective glare and objective parameters of optical quality.…”

Short‐term visual outcome after unilateral implantation of a trifocal diffractive presbyopia‐correcting intraocular lens

“…It is questionable whether the ongoing adaptation of her visual system to the new lens will improve her visual perception . VA is only one metric and cannot completely describe the efficiency of a multifocal IOL, as the ultimate criterion is patient satisfaction . Large‐scale studies and clinical trials will help us better understand the limits of tolerance in patients with unilateral implantation of a trifocal IOL and a phakic or monofocal pseudophakic fellow eye.…”

Linsenchirurgie: Einsatz von multifokalen Intraokularlinsen

“…In einer Metaanalyse, die 2016 durchgeführt wurde, lag der unkorrigerte binokulare Fernvisus bei 0,05 ± 0,01 logMAR. 80,1 % der Patienten waren nach dem Eingriff brillenfrei [6].…”
