Calcification of a hydrophilic acrylic intraocular lens: Case report with laboratory analysis
Calcification d’un implant intraoculaire acrylique hydrophile : cas clinique avec analyses physicochimiques
 

Figure 1




Figure 1 : 

Slit lamp photograph of the patient's right eye prior to explantation and lens exchange. The intraocular lens is well-centered, but the optic is opacified.


Figure 2




Figure 2 : 

Gross photograph of the explanted lens showing dried ophthalmic viscosurgical device and balanced salt solution on the lens surface. The optic and haptics appear opacified. A radial cut in the optic that was made during explantation can be seen between the distal haptics.

Figure 3 : 

A. Anterior segment optical coherence tomography of the explanted lens in a model eye revealing a band of granular material beneath the optic surface. The distribution of the granules is denser close to one of the optic surfaces. B. Anterior segment Sheimpflug photograph of the explanted lens in a model eye demonstrating significant light scattering in the areas of granular material (76 and 223 computer compatible tapes). The area with higher scattering (bottom surface in the Scheimpflug photograph) corresponds to the region with denser granular material (upper surface on the optical coherence tomography).

Graph showing the % light transmittance from 350 to 850nm of the explanted intraocular lens and a control hydrophilic acrylic intraocular lens.

Figure 5 : 

A. Light photomicrograph of the optic and optic/haptic junctions showing dried ophthalmic viscosurgical device, balanced salt solution and cellular surface deposits. Granular deposits are clearly visible within the optic and the proximal optic/haptic junction (original magnification×20). B. High magnification light photomicrograph of a haptic edge showing granular deposits within the intraocular lens. There is a clear band just beneath the intraocular lens surface that contains no granules (original magnification×100). C. Light photomicrograph demonstrating positive staining of the granules for calcium with alizarin red (original magnification×100). D. Light photomicrograph of a Von Kossa-stained cross section through the intraocular lens optic showing subsurface granular deposits that stain positively for calcium (original magnification×100). Calcified granules of smaller size are also present and densely distributed within the center of the optic. The intraocular lens surface outline is clearly visible.
