Long-term gonioscopy follow-up of eyes with posterior chamber lens implants and no iridectomy.

One hundred eyes which had undergone extracapsular cataract extraction with no iridectomy followed by insertion of a posterior chamber lens were examined gonioscopically 1 to 4.7 years postoperatively to determine the prevalence of asymptomatic angle closure from pupillary block. Since no peripheral anterior synechiae (PAS) characteristic of pupillary block were found, there seems to be little risk that these eyes will develop angle-closure glaucoma. During the study small PAS were noted adjacent to many haptics implanted in the ciliary sulcus.
