300 primary anterior chamber lens implantations: gonioscopic findings and specular microscopy.
A total of 300 consecutive quadruped anterior chamber intraocular lenses were implanted. Gonioscopy was performed in all cases and prospective specular microscopy was performed in the last 97 cases. Iris tucking of at least one lens foot was noted in 28% of the cases. Tucking occurred less often (20% of the cases) when the lens length was 13 mm, increasing with lens lengths longer and shorter than 13 mm. Slight lens rotation was noted in 8% of the cases. Blood vessels (rarely appearing to be neovascular) were noted around an implant foot or in the anterior chamber angle near a lens foot in 30% of the cases. A statistically significant difference in endothelial cell loss was noted between the Choyce lens (18.6%) and the Tennant lens (12.4%).
