Cytokeratin in lens epithelial cells and its effect on anterior lens capsule opacification.

Postoperative lens capsule opacification is a complication of extracapsular cataract extraction. To avoid this problem, we aspirated the epithelial cells lining the internal surface of the capsular bag. Anterior capsule specimens collected three and six years after the first surgical intervention (extracapsular cataract extraction with intercapsular implantation of a poly[methyl methacrylate] intraocular lens) and in vitro studies of epithelial cell cultures revealed the presence of intracellular and extracellular cytokeratin.

Small capsulotomy and great implant lens.

The envelope technique provokes in all cases a rupture of the zonules. With capsulorhexis, the advantages of working inside the envelope are lost, but the zonules are better protected. The capsulokleisis--or similar capsulotomies--combines the advantages of both systems.

Early results with the 8 mm and 9 mm HEMA disc intraocular lens.

This study presents our experience with 34 HEMA disc intraocular lenses implanted in the capsular bag. Despite the small number of cases and the relatively short mean postoperative follow-up of nine months, the results show a low incidence of uveitis and capsular fibrosis and excellent biocompatibility. The following complications were observed: four luxations of the 8 mm lens and one of the 9 mm lens in the anterior chamber.
