Can someone explain, in “Optics for Dummies” terms, how intraocular lens power relates to contact lens prescription power? I’ve had monovision correction with contacts for several years; -9.0 D for distance, -5.75 D for close-up. During cataract surgery, my doctor implanted a 12.0 D intraocular lens for distance and a 14.0 D lens for close-up. Intuitively, I would think the more “powerful” lens (14.0 D) would be for distance while the smaller number (12.0 D) would be for close-up. And I have no idea how a -9.0 D corrective lens prescription equates to a 12.0 D intraocular. I work in the scientific research field, and I’m usually pretty good at tracking down such info, but I can’t wrap my head around this. Thanks for any help.
