Abstract
Gonioscopy was performed in 64 patients 3–8 (mean 4) months after intracapsular cataract extraction with implantation of the semiflexible McGhan/3 M, style 70, anterior chamber lens. Iris tucking was present in 19 (30%) eyes. Iris‐haptic adhesions (strands of iris‐like tissue encircling the lens feet) were present in 24 (38%) eyes. Absence of iris tucking was statistically significantly (P ≦ 0.05) related to surgical expertise, while the occurrence of iris‐haptic adhesions was independent of surgical experience. Pupillar deformation, usually an elongation in the axis of the implant, was present in 50%. The absence or presence of an abnormal gonioscopy could not with certainty be deduced from the form of the pupil. The majority of gonioscopically visible pathological changes in the chamber angle were located posterior to the trabecular meshwork.
