    Purpose. The goal is to expand the currently known classifications of the capsular block syndrome (CBS) based on the analysis of publications and own experience, taking into account the data of modern research methods.

    Material and methods.All cases of the capsular block syndrome described in the available scientific literature were analyzed, as well as observations from our own practice with the use of optical coherence tomography of the IOL-capsular bag complex (Optovue).

    Results. An extended classification of the CBS is based on the classification according the time of onset (intraoperative, early and late postoperative) proposed by Miyake K. et al. (1998). The enlarged classification reflects the possible causes of intraoperative CBS, a variety of clinical and morphological manifestations of CBS in the postoperative period.

    Conclusion. The proposed classification integrates our own experience and analysis of clinical cases from the literature and can be used for a uniform description of all detected cases of CBS.

    Key words: capsular block syndrome, lens capsule, complications of cataract surgery, secondary cataract, optical coherence tomography of anterior segment, capsular bag distension syndrome.
