Peripheral anterior synechiae formation with anterior chamber intraocular lenses.

In a cross-sectional study, 88 eyes with anterior chamber intraocular lenses (AC-IOLs) were evaluated by goniophotography by one masked observer for the presence of peripheral anterior synechiae (PAS) and by another masked observer for the length of the AC-IOL. Sixty-eight of the 88 lenses had PAS which were strongly correlated with the lens being oversized (P less than .001). However, differences in haptic style or lens rigidity were not associated with the presence of PAS.
