Definition
Implantation of two or more intraocular lenses (IOLs) into the posterior chamber of the same eye.
Epidemiology
Due to its spectrum of indications for piggyback IOL implantation, this type of refractive surgery is performed infrequently.
History
Piggyback IOL implantation was first reported by J. Gayton in 1993. He implanted a pair of plano/convex PMMA IOLs with the plano surfaces opposed in a capsular bag/sulcus configuration in an eye with microphthalmos (Gayton and Sanders 1993). J. P. Gills was the next surgeon to perform piggyback implantation, reporting a series of eyes in which he implanted multiple PMMA IOLs in the capsular bag. In 1995, J. P. Gills showed surgical videos in which he implanted up to four IOLs into the same capsular bag in an effort to enhance depth of field. Application of foldable IOLs to piggyback implantation finally led to a marked increase of...
