Lente intraocular fáquica de colámero tórica implantada en piggyback: manejo de la ametropía pseudofáquica y la disfotopsia negativa

Abstract

As a result of the successful development of corneal refractive techniques over the past three decades, an increasing number of patients who have undergone refractive surgery are now seeking surgical solutions for dysfunctional or cataractous lenses, with high expectations for precise visual outcomes. Refractive calculation in these cases poses a challenge for the surgeon. One available option to address residual postoperative refractive errors after lensectomy is the implantation of a secondary intraocular lens in a piggyback configuration. We present a unique case of implanting a collamer phakic intraocular lens (ICL) in a piggyback fashion, addressing not only residual refractive error following cataract surgery but also severe negative dysphotopsia in a patient who had undergone LASIK 20 years earlier and already had a posterior capsulotomy.
