Capsular bag distension syndrome

CBDS can be classified by time of onset, whether it occurs intraoperatively, early postoperatively (first few weeks), or late postoperatively (months or years). Intraoperative CBDS is felt to result from high irrigation pressures during hydrodissection which hyperdistend the posterior capsule, increasing the risk for capsule rupture. Early postoperative CBDS is associated with incomplete viscoelastic removal posterior to the IOL with resulting anterior IOL displacement leading to a myopic shift, anterior chamber shallowing, and IOP elevation. Late CBDS classically does not exhibit these symptoms and is only noticed due to the decreased visual acuity recognized by the patient.
