Experimental evaluation of a posterior chamber lens fixated with Dacron

A posterior chamber intraocular lens using Dacron fibers to achieve fixation to the iris was studied. The lens was inserted in rabbit eyes following extracapsular lensectomy, and in primate eyes after lensectomy, vitrectomy, and peripheral iridectomy. Surgical implantation of the lenses was simple and quick, and no operative complications occurred. Clinically, no difference was noted in the amount of inflammation in eyes receiving a lens with or without Dacron. None of the lenses implanted in primate eyes dislocated; one placed in a rabbit eye dislocated anteriorly. Postmortem examination demonstrated firm Dacron adherence to iris tissue in all but the one eye with a dislocated lens.
