Primary calcareous degeneration of the cornea.

Primary calcareous degeneration is a rare corneal disease. In the past 50 years, only four cases have been described. We present the case of a 26-year-old male patient with progressive calcium deposition in both eyes with negative laboratory parameters.

Light scattering and light transmittance in a series of calcified single-piece hydrophilic acrylic intraocular lenses of the same design.

Purpose: To evaluate light scattering and light transmittance of Ioflex hydrophilic acrylic intraocular lenses (IOLs) explanted because of clinically significant opacification secondary to calcification.

Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.

Early opacification of silicone intraocular lenses: Laboratory analyses of 6 explants.

Purpose: To report laboratory analyses of 6 intraocular lenses (IOLs) explanted from patients who had visual disturbances caused by early postoperative opacification of the lens optic.

Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.
