Morphological changes and lens position were examined in 66 patients 3 to 5.5 (mean 4) months after extracapsular cataract extraction with intended implantation of posterior chamber lenses in the ciliary sulcus. Important findings were: capsulotomy‐requiring secondary cataract (3%), iris‐lens synecchiae (18%), iris‐capsule synecchiae (14%), pupillar capture (2%) and haptic‐malposition (17%). The lens optic was slightly decentered in 33%. The internal anterior chamber depth was measured with optical pachymetry and averaged 3.5 mm (range 2.3–4.5 mm). The central distance between the posterior lens surface and the posterior capsule (LPCD) was measured pachymetrically and averaged 0.14 mm (range 0‐0.6 mm).
