PURPOSE: To describe ocular complications resulting from inverted insertion of a Kelman Multiflex anterior chamber intraocular lens (ACIOL). • DESIGN: Retrospective observational case series. • METHODS: We describe the outcomes of 4 cases of complicated cataract surgery in which a flexible openloop polymethylmethacrylate (PMMA) ACIOL (Kelman Multiflex type) was placed in an inverted configuration, all of which were referred to a single institution. • RESULTS: In all 4 cases, the placement of an inverted ACIOL resulted in ocular complications including chronic iritis, cystoid macular edema, pupil capture, iris adhesions, and corneal decompensation. • CONCLUSIONS: Inadvertent inverted placement of the Kelman Multiflex anterior chamber intraocular lenses can lead to a constellation of severe ocular complications. When inserting such lenses, the surgeon should ensure that the lens is correctly oriented such that the optic vaults anteriorly and not posteriorly. (Am J Ophthalmol 2011;152:122-125.
Negative dysphotopsia associated with implantation of the Z9000 intraocular lens
Journal of Cataract and Refractive Surgery, 2005
Uneventful small-incision cataract surgery was performed in a 70-year-old man and a 62-year-old woman with implantation of a Tecnis Z9000 intraocular lens (IOL) (Pharmacia). No ocular pathology was present in the patients preoperatively. Unsolicited complaints of negative dysphotopsia were made postoperatively, and the symptoms have persisted for more than 1 year in both patients. Symptomatic negative dysphotopsia may be seen in association with the Z9000 IOL.
