Abstract Details


To report two different presentation of late capsular block syndrome (CBS) through slit lamp images and anterior segment optical coherence tomography (OCT).


Fundación Alcorcón University Hospital, Department of Ophthalmology, Madrid, Spain.


Four consecutive patients with late CBS were reviewed: 3 of them had milky fluid collection in the capsular bag, considered typical of a late CBS. Only one of them had transparent liquid together with an induced myopia, which is most frequent in early postoperative CBS (day 1 to 2 weeks postoperatively). Cases were illustrated using the slit lamp and anterior segment OCT Cirrus-Hd 4000 ( 5 lines raster Anterior Segment protocol). All cases were treated with neodymium: YAG laser capsulotomy.


Slit lamp images and Anterior Segment OCT confirmed the presence of milky and transparent fluid between posterior intraocular lens( IOL) surface and the opacified posterior capsule. After capsulotomy, the corrected distance visual acuity improved in 3 cases ( mean LogMAR 0.40) and did not change in one case. The induced myopia, as well as the posterior capsule distention, were resolved. There were no complications, inflammation, or significant intraocular pressure changes.


Postoperative capsular block syndrome usually appears 2 years after cataract surgery, as an accumulation of a milky-white or less commonly, transparent fluid between the posterior capsule and the posterior IOL surface. Most of the time is asymptomatic, and cannot be diagnosed unless there is posterior capsule opacification. It is for that reason, anterior segment OCT could be useful for an early diagnosis. Treatment with Nd-YAG posterior capsulotomy brings good visual results.
