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 6.0 mm optics (X-60, VA-60BBR) and 7.0 mm...
متن کاملSurgical Outcome of Simultaneous Intraocular Lens Rescue and Sutureless Intrascleral Tunnel Fixation of Dislocated Intraocular Lenses.
PURPOSE To report short-term surgical outcomes of single-stage simultaneous rescue and sutureless intrascleral fixation of dislocated intraocular lens (IOLs). METHODS Sixteen eyes of 16 patients who underwent simultaneous rescue and intrascleral fixation of dislocated 3-piece IOLs were retrospectively evaluated. Partial thickness limbal-based scleral flaps (2.0 × 2.0 mm) were created, and a 2...
متن کاملEffect of decentration of wavefront-corrected intraocular lenses on the higher-order aberrations of the eye.
OBJECTIVE To evaluate the theoretical effect of decentration of aspherical intraocular lenses (IOLs) and wavefront-corrected IOLs up to the sixth order on higher-order aberrations (HOAs) (third through sixth order) of the eye. METHODS An aspherical IOL with HOAs of fourth-order spherical aberrations only (-0.287 microm with a 6-mm pupil) and a wavefront-corrected IOL with HOAs of equal magnit...
متن کاملHigher-order aberrations after implantation of iris-fixated rigid or foldable phakic intraocular lenses.
PURPOSE To evaluate higher-order aberrations (HOAs) after implantation of Artiflex phakic intraocular lenses (pIOLs). SETTING Department of Ophthalmology, Academic Hospital Maastricht, Maastricht, The Netherlands. METHODS This retrospective comparative case series comprised 27 eyes (14 patients) that had Artiflex pIOL implantation and 22 eyes (13 patients) that had Artisan pIOL implantation...
متن کاملScleral Fixation Intraocular lenses
Background: The 1ry indication for scleral fixation of intraocular lenses (IOL) is dislocation as a principal complication of cataract surgery. Inadequate capsular support is the most common cause of IOL dislocation. Other indications include traumatic phakic lens dislocation (cataractous or clear), surgically aphakic eyes or anterior chamber IOL with complications (persistent hyphema, uveitis)...
