Long-term pathological follow-up of 2-loop iridocapsular intraocular lens.

Published: February 2011

We analyzed an enucleated postmortem eye from an 86-year-old donor who had a 2-loop iridocapsular intraocular lens (IOL) that had been implanted at least 30 years earlier. High-frequency ultrasound showed a relatively well-centered iris-supported optic in front of the pupil. Gross and light microscopic analyses of the eye and the IOL showed loop fixation outside the capsular bag remnants, a thickened cornea, mild attenuation of the corneal endothelium, multiple areas of iris trauma secondary to haptic abrasion, fragments of iris tissue attached to the haptics, as well as pigment dispersion within the eye with pigmented epithelial cells attached to the IOL haptics. Histopathological examination of the posterior segment was unremarkable.

An 86-year-old man with a Binkhorst 2-loop intraocular lens (IOL) that was implanted in the pupillary sphincter 33 years earlier was examined. The pupil of the implanted eye with the Binkhorst IOL was irregular and the eye had pseudoexfoliation (PEX) syndrome. Pupillary erosion resulted from rubbing of the IOL edge against the pupillary sphincter with PEX material.

A randomised controlled trial in progress for more than five years assessed 333 eyes by three methods of cataract surgery. These were (A) intracapsular extraction and contact lens usage; (B) intracapsular extraction and implantation of an iris supported lens (Federov I); and (C) extracapsular extraction and implantation of an iridocapsular lens (Binkhorst 2-loop). This paper reports the use of a weighting scale for rank scoring complications which are dissimilar or are mutually exclusive (for example, capsular versus contact lens problems) to allow the use of non-parametric statistics for comparing disparate features.

A randomised controlled trial in progress for more than five years, with no loss to follow-up (except death), assessed 333 eyes treated by three methods of cataract surgery. They were (A) intracapsular extraction and contact lens usage, (B) intracapsular extraction and implantation of an iris supported lens (Federov I), and (C) extracapsular extraction and implantation of an iridocapsular lens (Binkhorst 2-loop). The purpose of the paper is to report interim visual results, complications, and corneal endothelial cell loss.

Central corneal endothelial cell density was estimated in 33 consecutive patients preoperatively and at monthly intervals for 6 months after cataract surgery. The patients were divided into 3 groups by a random procedure to have either intracapsular extraction or intracapsular extraction plus Federov 4-loop iris clip lens, or extracapsular extraction with Binkhorst 2-loop iridocapsular lens. In all groups the greatest cell loss had occurred by one month and thereafter no accelerated loss was apparent except in individual patients.
