Intraocular lens tilt and decentration: a concern for contemporary IOL designs.
PURPOSE To review published studies reporting the posterior chamber intraocular lens tilt and decentration after surgically uneventful implantation. Potential influences of normally occurring misalignment of modern designs of IOL on the optical performances are discussed. MATERIALS AND METHODS Published theoretical and clinical studies in relation to primarily implanted posterior chamber intr...
متن کاملAnterior capsule contraction and intraocular lens decentration and tilt after hydrogel lens implantation.
AIM To prospectively investigate changes in the area of the anterior capsule opening, and intraocular lens (IOL) decentration and tilt after implantation of a hydrogel IOL. METHODS 100 patients underwent implantation of a hydrogel IOL in one eye and an acrylic IOL implantation in the opposite eye. The area of the anterior capsule opening, and the degree of IOL decentration and tilt were measu...
متن کاملImpact of intraocular lens haptic design and orientation on decentration and tilt.
PURPOSE To assess the effect of intraocular lens (IOL) orientation (vertical versus horizontal) and haptic design (1-piece versus 3-piece) on centration and tilt using a Purkinje meter. SETTING Moorfields Eye Hospital NHS Foundation Trust, London, United Kingdom. DESIGN Randomized pilot study with intrapatient comparison. METHODS In part 1 of this study, patients received plate-haptic IOL...
متن کاملComparison of intraocular lens decentration and tilt measurements using 2 Purkinje meter systems.
PURPOSE To evaluate the difference in intraocular lens tilt and decentration measurements with 2 Purkinje meters. SETTING Vienna Institute for Research in Ocular Surgery, Hanusch Hospital, Vienna, Austria. DESIGN Prospective evaluation of diagnostic test. METHODS This single-center study included pseudophakic patients in 2 substudies in which 3 consecutive measurements were performed with...
متن کاملIntraocular lens tilt and decentration measurements: Purkinje imaging versus Scheimpflug imaging
Purpose: To measure tilt and decentration of intraocular lenses (IOLs) with Scheimpflug and Purkinje imaging systems. Methods: Measurements of IOL tilt and decentration were obtained using a commercial Scheimpflug system (Pentacam, Oculus) and custom algorithms, and a custom-built Purkinje imaging apparatus. Both methods were validated with a physical model eye where tilt and decentration can b...
