We have many different IOL designs available for use in cataract surgery and even within the most popular category (single-piece, hydrophobic acrylic, aspheric monofocal IOLs) there are multiple choices. These IOLs often are more similar than different, but there are crucial differences that you must know to select the best IOL for each specific patient. There is no perfect IOL and don’t believe the sales agents who tell you that their lens is the best across the board. You must judge for yourself.
In this photo, where the two images have been placed at the same magnification, the overall optic diameter for both is 6 mm but the IOL on the left appears to have a null-zone in the periphery with a focusing optic of about 5 mm. Why? The answer to this, and much more, is revealed in the video below.
