Effects of optical diameter of intraocular lenses with intrascleral fixation on higher-order aberrations.

Background: Intrascleral fixation of an intraocular lens (IOL) is used in eyes that lack capsular support. The aim of the study is to determine whether a larger optical diameter IOL will decrease the higher-order aberrations (HOAs) when the haptics are extended for intrascleral fixation than a smaller diameter IOL.

Methods: Three-piece acrylic IOLs with 6.
