Case Report: Explantation of A Binkhorst Iridocapsular Lens >30 Years After Implantation in an Eye With Pseudoexfoliation Syndrome
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. The IOL was removed because of visual distortion and intense pseudophakodonesis.
Gross and light microscopic analyses showed no irido-fibro-lenticular adhesions over the lens or fragments of iris tissue attached to the lens. Scanning electron microscopy showed several pores of different sizes. No inflammatory cells were present, suggesting that the IOL was well tolerated.
The case suggested that the pupillary ruff was not a good location for implantation of an IOL in an eye with PEX. Caution is recommended before implanting or suturing an IOL close to the pupillary border in eyes with PEX during cataract surgery.
