With the implantation of a secondary piggyback lens, the piggyback procedure was extended to address pseudophakic refractive errors in normal and postpenetrating keratoplasty eyes.

Ophthalmology 1998, 105:1759-1764. The number of outliers are reduced with the Holladay II formula for piggyback lens power calculation. The accurate results confirm the importance of additional measurements for improved predictability.

J Cataract Refract Surg 1999, 25:863-867. The first indication of possible long-term complications with piggybacks, cell growth between piggybacked lenses is associated with refractive change in acrylic piggybacks. Prevention of the problem would involve a change in surgical technique.
