چکیده
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 lenses is the ideal procedure for those who are beyond the range of many other procedures.

متن کاملAccuracy of intraocular lens power calculations using the Zeiss IOL master. A prospective study.
PURPOSE Partial Coherence Interferometry (PCI) is a fast, noncontact method to calculate lens implant power for cataract surgery. It has been reported as a potentially more accurate method than ultrasound biometry. Prospective study of the refractive outcomes of a consecutive series of patients undergoing phacoemulsification surgery with preoperative biometry by both ultrasound A-scan and PCI. ...

Background and Objective: Ocular biometry refers to the measurement of the axial length of the eye and thickness of the intraocular structures. This process is routinely performed for all patients before cataract surgery. The accuracy of the biometric data is directly associated with the refractive status after cataract surgery. Currently, two methods of biometry, namely ultrasound and optical ...
