Aims/Purpose: To describe the use of anterior segment optical coherence tomography (AS-OCT) to detect the presence of a pre-existing posterior capsule defect in patients with posterior polar cataract prior to surgery.
Methods: Three
patients with posterior polar cataract were assessed preoperatively using
AS-OCT, which revealed an intact posterior capsule in one patient and a
pre-existing posterior capsule deficit in the other two patients that was not
visible by slit-lamp examination. Phacoemulsification and intraocular lens
implantation were performed on all of the patients.
In our case
studies, we used AS-OCT, which is an imaging technique that overcomes the
constraints of slit-lamp scanning. In cases 2 and 3, the posterior capsule was
ruptured, whereas case 1 had an intact capsule. Because of the optical density
of the overlaying lens opacity, this imaging technology may be unable to detect
a "genuine" capsular defect, which could lead to false positive
results.
