Unintentional Filtration Following Cataract Surgery

Complications of inadvertent filtering blebs after cataract extraction

“…5 The incidence is reported to be between 1.0% and 7.7%. 4 However, rates as low as 0% have been reported following phacoemulsification. 6 In the past, scleral incisions were more common than clear corneal incisions in cataract extraction and likely contributed to a higher incidence of internal wound gape and thus inadvertent bleb formation.…”

“…2 Complications associated with these created blebs include, but are not limited to, a shallow anterior chamber, dellen formation, leakage of the bleb, filtration failure, hypotony, macular edema, and blebitis that can progress posteriorly and cause sightthreatening endophthalmitis. 2,4,20,21 If these blebs become infected, even with successful treatment, they are extremely susceptible to recurrent infections. 22 Late infection and endophthalmitis are serious complications that can follow trabeculectomy and are associated with decreased visual acuity, hypopyon, a red and tearing eye, chemosis, corneal edema, and foreign-body sensation.…”

“…1 Although 4 of 5 inadvertent blebs will close on their own within 6 months, the filtering blebs can lead to significant morbidity, including hypotony, macular edema, shallow anterior chamber, choroidal detachment, dellen formation, and blebitis, that can progress to sight-threatening endopthalmitis. [2][3][4] We report 2 cases that demonstrate the uncommon post-cataract-extraction complication of inadvertent filtering bleb from scleral wounds. These cases demonstrate 2 complications of inadvertent filtering blebs occurring many years after cataract extraction.…”

Limbal cyst following blunt trauma in an operated case of congenital cataract: a rare scenario

“…The incidence of unintentional filtration following cataract surgery varies from 1% to 7.7% 1. The duration for the development of the cyst following cataract surgery varies from several months to years in non-traumatic cases.…”

Schmalmesserschnitt und Stufenschnitt bei der Kataraktoperation

“…Es stellt eine latente Infektionsgefahr für das Auge dar, was im Extremfall zur Panophthalmie führen kann, und behindert bei Persistenz das Tragen von Kontaktschalen [32]. Wie Swun und Campbell [27] zeigten, verschliesst es sich aller dings in 4A der Fälle innert 6 Monaten spontan, ohne Schaden angerichtet zu haben.…”
