Histological findings in angulated posterior chamber lenses

The histological observations of 6 cadaver eyes containing a SIMCOE posterior chamber lens are reported. Reduction of loop diameter 10 months after implantation is demonstrated. The cellular response of the local tissue is demonstrated with and without the loop contact. In long term follow up the loop support in the sulcus rim was seen to lead to a canal formation within the ciliary body. Scanning electron microscopy revealed a compact cover around the peripheral end of the loops which showed tight contact to the synthetic material.
