[Capsular sack implantation of heparin-modified posterior chamber lenses]

In a prospective study, heparin surface modified posterior chamber lenses were implanted into the capsular bag in 50 patients. The exact positioning of the biconvex, one-piece lens in the bag is the prerequisite for good centration and for an optimal result. The hydrophilisation of the originally hydrophobic PMMA material is achieved by heparin surface modification and results in less inflammation. The aim of this study was to investigate the postoperative behavior of the HSM posterior chamber lens implanted in the bag, with special consideration given to intraocular inflammation. In the postoperative follow-up time of one to seven months, hundred percent of the patients with physiological fundus reached a postoperative visual acuity of 0.7 or better.
