Refractive Changes Induced by Intraocular Lens Tilt and Longitudinal Displacement

Etiology and Clinical Presentation of Astigmatism

“…The refractive results of displacement of an intraocular lens are known for many years (Lakshminarayanan, 1986). Using a modified Gullstrand schematic model eye, the authors have computed the amount of spherical and cylindrical errors that are induced due to the tilt and/or displacement of the intraocular lens.…”

Keratometry and post-operative astigmatism

“…Intra ocular lens position is theoretically important but inves tigations of optical aberrations of decentred and tilted intraocular lenses have shown the effects to be smal1. 4 In those cases where high degrees of astigmatism result from lens displacement, abnormalities of lens position will be readily detected by slit-lamp biomicroscopy .…”

Tilt and Decentration of Intraocular Lenses-a Brief Review

“…Copyright: to assess IOL tilt and decentration in vivo, using either Purkinje meters [33][34][35][36][37] or Scheimpflug imaging [38,39]. To assess tilt and decentration in relation to HOAs after implantation of an aspheric IOL in patients, clinical studies were conducted [40,41] and it was shown that the limits for tilt and decentration for proper functioning of AIOLs found in laboratory studies were respected after AIOL implantation in vivo, resulting in a reduction of total SA.…”
