Background:
Delamination of the anterior lens capsule producing a double-ring sign during continuous curvilinear capsulorhexis is commonly associated with true exfoliation syndrome.
Methods:
Previous studies have concentrated on light- and transmission-electron microscopic features and correlated this with the histopathology of these anterior capsules. To our knowledge, this is the first report of the use of high-resolution spectral-domain optical coherence tomography to delineate delamination of the anterior lens capsule, incidentally detected during cataract surgery.
