Objectives: Automated piggybacks are purported to make drug administration safer and more reliable. We evaluated the human factors of piggyback infusion, investigated the practice in our institution, and analyzed incidents from an anonymous database to better characterize the practice and substantiate these assertions. Methods: To find examples of problems with piggyback, or secondary infusions...

AIM To assess the refractive outcome of clear lensectomy combined with piggyback intraocular lens implantation in highly hyperopic patients. METHODS This case review included 19 eyes of 10 patients with high hyperopia and axial length less than 21mm. Intraocular lens power was calculated for emmetropia using the Holladay II formula in 17 eyes, and SRK/T formula in 2 eyes following clear lens ...

For cataract patients with extreme refractive errors, implanting 2 IOLs in 1 eye, piggyback style, provides an opportunity to treat the refractive error along with the cataract. The piggyback lens implantation strategy (Figure 15-1) can be used to treat high hyperopia,1-5 extremely high myopia,6 and high astigmatism (using toric lenses). In many cases, clear lens replacement with piggyback lens...

Many tools, including performance analysis tools, tracing libraries and application level checkpointers, add piggyback data to messages. However, transparently implementing this functionality on top of MPI is not trivial and can severely reduce application performance. We study three transparent piggyback implementations on multiple production platforms and demonstrate that all are inefficient ...

BACKGROUND We report the case of a 40-year-old female patient treated with implantation of the Acrysof® IQ ReSTOR® lens (Alcon, Fort Worth, Tex., USA) with overlaying Acrysof EXpand® minus piggyback lens (Alcon). METHODS The patient had high myopia and was diagnosed with presbyopia and bilateral posterior subcapsular cataract. She desired to be spectacle-free and opted to undergo bilateral pl...

PURPOSE To evaluate the efficacy, predictability, and safety of three different procedures (intraocular lens [IOL] exchange, piggyback lens implantation, and LASIK) to correct residual refractive error following cataract surgery. METHODS A retrospective multicenter study comprised 65 eyes of 54 patients that underwent phacoemulsification, resulting in a unacceptable final refractive error. Ey...

Piggyback orthotopic liver transplantation was performed in 24 patients during a period of 4 months. This represented 19% of the liver transplantation at our institution during that time. The piggyback method of liver insertion compared favorably with the standard operation in terms of patient survival, blood loss, incidence of vascular and biliary complications, and rate of retransplantation. ...
