Surgical management and outcomes of dislocated intraocular lenses.

Abstract

To evaluate the surgical management and visual acuity outcomes in a large series of patients with dislocated intraocular lenses (IOLs). Retrospective consecutive noncomparative case series. All patients who underwent surgical management of dislocated IOLs by two vitreoretinal surgeons at one institution between January 1, 1991, and March 31, 1998. Demographic and clinical data were abstracted from patients' medical records. Visual acuity at final follow-up and surgical complications. The study population consisted of 110 patients, with a median follow-up interval of 50 weeks after dislocated IOL management. Surgical techniques included IOL repositioning in 93 (84.5%) eyes, IOL exchange in 16 (14.5%) eyes, and IOL removal in 1 (1 %) eye. Final visual acuity was > or =20/40 in 63 patients (57%) patients, 20/50-20/200 in 34 (31%) patients, and <20/200 in 13 (12%) patients. Ninety-nine (90%) patients had stable or improved final vision. Observed complications included postoperative retinal detachment in 7 (6.3%) eyes, chronic cystoid macular edema in 19 (17%) eyes, and suprachoroidal hemorrhage in 1 (1%) eye. Surgical management of dislocated IOLs usually results in satisfactory visual outcomes. Pre-existing ocular pathology and postoperative complications may limit final vision.
