Hello! I had cataract surgery many months ago with an acrylic multifocal iol but it didn't work due to unbearable and multiple dysphotopsias that never diminished over the time. The multifocal had squared edges. It's important to specify this because 2 weeks ago the multifocal lens was removed and it was placed an acrylic monofocal that solved almost all my glare and halos problems and also improved my sight but the flashing issues is still there annoying as ever and it is without doubt related to the squared edge because I don't have any other explanation.
Lighting must hit the lens' edge peripherally (between 90 to 60 degrees), usually from the side but it works also from above. The reflection hits the edge producing internal reflections and with every micro eye movement you can see your sight flashing, flickering. If you keep your eye absolutely steady, no flashes at all.
I'm gonna my surgeon to do the second eye using a monofocal silicone iol, with rounded edge (one rounded edge, usually the posterior) to see if it can ameliorate the issue.
Someone went through this?
