Experimental Investigation on Mechanism of Hydrophilic Acrylic Intraocular Lens Calcification

American Journal of Ophthalmology, 2011
To construct a model simulating intraocular lens (IOL) opacification attributable to the formation of calcium phosphate deposits and to investigate the kinetics of deposit formation.Prospective laboratory investigation.Department of Ophthalmology, Medical School and Department of Chemical Engineering, Laboratory of Inorganic and Analytical Chemistry ...

Calcification of a Hydrophilic Acrylic Intraocular Lens: Case Report With Laboratory Analysis

Journal Francais D'Ophtalmologie, 2013
We analyzed a single-piece plate-type hydrophilic acrylic posterior chamber intraocular lens (IOL) that was explanted due to a progressive loss of vision, which occurred 6 years after uncomplicated phacoemulsification. Gross and light microscopy, as well as anterior segment optical coherence tomography (OCT) revealed granular deposits below the IOL ...

Calcification of a Rayner Centerflex 570H Hydrophilic Acrylic Intraocular Lens Following Vitrectomy for Retinal Detachment: A Clinicopathologic Report

European Journal of Ophthalmology, 2010
PURPOSE: The case of a 71-year-old man who complained of progressive, unilateral visual blurring following vitrectomy for retinal detachment due to opacification of his Rayner Centerflex 570H intraocular lens (IOL) implant is reported.

Intraocular Lens Calcification After Keratoplasty

Cornea, 2013
To report calcification of intraocular lenses (IOLs) after various keratoplasty procedures.Clinical data of all cases with calcified IOLs after keratoplasty procedures were analyzed. A total of 6 explanted IOLs were analyzed with light microscopy before and after staining with 1% alizarin red and the von Kossa method.A total of 7 cases occurred after ...

Calcification of Intraocular Implant Lens Surfaces

Langmuir, 2004
Calcification of octacalcium phosphate [Ca8H2(PO4)6 x 5H2O, OCP] on differently packaged "Ultem" and "Surefold" intraocular implant lens surfaces has been studied in vitro in solutions supersaturated with respect to OCP at pH = 7.10 and 37 degrees C.

Assessing intraocular lens calcification in an animal model

Journal of Cataract and Refractive Surgery, 2001
To describe an animal model used to evaluate the propensity of various biomaterials to calcify intraocularly.Research Department, Allergan Inc., Irvine, California, USA.Intraocular lens (IOL) optic materials were implanted intramuscularly and/or subcutaneously in rabbits for up to 90 days.

Calcification of a hydrophilic acrylic intraocular lens: Clinicopathological report

Journal of Cataract and Refractive Surgery, 2008
A 72-year-old man who had phacoemulsification with implantation of an Akreos Adapt Advanced Optics (AO) IOL in the left eye complained of blurring vision 4 months postoperatively. Multiple fine white granules were found within the IOL. Intraocular lens exchange was performed at 7 months, and the explanted IOL was sent for histopathological analysis ...

Evaluation of calcification of a hydrogel intraocular lens by optical coherence tomography

Journal of Cataract and Refractive Surgery, 2004
We describe 2 cases of calcification of hydrogel intraocular lenses (IOLs) evaluated by optical coherence tomography. Dense or slight surface opacities of hydrogel IOLs were detected initially by slitlamp biomicroscopy in a 55-year-old woman and a 77-year-old woman.

Silicone intraocular lens surface calcification in a patient with asteroid hyalosis

Japanese Journal of Ophthalmology, 2012
To confirm a substance presence on the posterior intraocular lens (IOL) surface in a patient with asteroid hyalosis.An 80-year-old man had IOLs for approximately 12 years. Opacities and neodymium-doped yttrium aluminum garnet pits were observed on the posterior surface of the right IOL. Asteroid hyalosis and an epiretinal membrane were observed OD.

Surface deposits mimicking calcification on a hydrophobic acrylic intraocular lens

Journal of Cataract and Refractive Surgery, 2019
We describe the case of a female patient who had 3-piece silicone intraocular lenses (IOLs) bilaterally implanted after uneventful surgeries in 2007. Nine years later, the IOLs were explanted and exchanged with 3-piece hydrophobic acrylic IOLs because of cloudiness on their posterior aspect.
