To evaluate surgical outcomes after intraocular lens (IOL) exchange of refractive IOLs in dissatisfied patients
Retrospective case series of dissatisfied patients who sought consultation and subsequently underwent IOL exchange surgery to remove a refractive IOL. Data collected included pre-operative subjective and objective findings, surgical technique, and post-operative course.
Ten patients (eleven eyes) underwent IOL exchange of a refractive lens implant. All patients had subjective visual complaints prior to IOL exchange surgery. In spite of this, pre-operative best corrected distance visual acuity (BCVA) measured 20/30 or better in all eyes. During IOL exchange surgery, an aspheric monofocal type lens was placed either in the capsular bag or in the ciliary sulcus. Adjunctive anterior vitrectomy was performed as indicated for vitreous prolapse. Median follow up time after IOL exchange surgery was 2.4 months. Eight patients were satisfied with the results of the IOL exchange surgery while two patients felt the initial symptoms persisted after implant exchange surgery. BCVA at distance measured 20/25 or better in 8/11 eyes at 1 month. BCVA at distance in the remaining three eyes improved to 20/25 or better at 3 months (2 patients) and 6 months (1 patient). One patient had a complicated post-operative course necessitating repeat IOL exchange with scleral fixation due to inadequate capsular support.
IOL exchange is a feasible option for dissatisfied patients with persistent visual complaints after refractive intraocular lens placement.
