The finish of the bore hole in posterior chamber lenses






Folia Ophthalmologica Japonica 36(11): 2113-2115

The finish of the bore hole in posterior chamber lenses

Posterior synechia of the iris to the IOL surface is often seen in pseudophakic eyes with posterior chamber lenses. The synechia is sometimes limited to the site of the bore hole, and represents incarceration of the iris into the bore hole (iris incarceration phenomenon). The bore holes of posterior chamber lenses were examined with a scanning electron microscope. The finish of the hole edge was seen to be rougher than that of the edge of the optic area. The roughly finished edge, as well as the bore hole itself, are considered causes of such posterior synechia of the iris, giving rise to mechanical irritation and subsequent chronic inflammation, resulting in the iris incarceration phenomenon. The bore hole finish must be improved.
