Adherence and viability of porcine lens epithelial cells on three different IOL materials in vitro.

Background: The purpose of the study was to evaluate porcine lens epithelial cell (LEC) adhesion and viability on three different intraocular lens (IOL) materials.

Methods: The IOL materials tested were poly(methylmethacrylate) (PMMA), silicone and hydrophobic acrylate. Primary porcine LECs were cultured on four discs of each material over a period of 10 days and, additionally, on six discs of the hydrophobic acrylate over a period of 20 days.

In-the-bag dislocation of a hydrophilic acrylic intraocular lens.

We report a case of a dislocated hydrophilic acrylic intraocular lens (IOL) inducing astigmatism and causing chronic pain and cystoid macular edema as a result of a folded haptics, which mechanically irritated the iris. Scanning electron micrographs of the explanted IOL, including the capsular bag, showed a folded IOL haptic incarcerated in the capsular bag.

[Enterococcal endophthalmitis following cataract surgery].

Background: Postoperative endophthalmitis can be subdivided into acute and chronic forms which are typically caused by different organisms. Enterococcus faecalis is an organism which normally causes an acute form of endophthalmitis.

Patients And Methods: We report on four cases of different forms of endophthalmitis following cataract extraction and intraocular lens (IOL) implantation who had been referred to our institution between 1998 and 2001.
