What is difference between traditional and premium IOL implants?
In cataract surgery, the eye’s natural lens is replaced with an artificial intraocular lens (IOL). A traditional IOL can correct for either nearsightedness or farsightedness, but you will probably still need to wear glasses to see at some distances. Premium IOLs correct for more complex refractive errors, including astigmatism and presbyopia, or the inability to focus on close objects — as in people who otherwise need bifocals. If you choose to receive premium IOLs, you may never have to wear glasses again.
