Postoperative refractive outcome largely depends on the accuracy of calculating power of implanted IOL. Lens power calculation can be done by conventional ultrasound biometry and partial coherence laser interferometry (IOL Master). The aim was to compare the accuracy of IOL power calculations using conventional ultrasound biometry and partial coherence laser interferometry.40 eyes were included...

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: The main purpose of this paper is to compare the reliability and repeatability of data obtained clinically with the IOL Master with those using a standard applanation ultrasound biometry on different refractive error types to measure axial length. Patients and Methods: 39 patients were examined by both the IOL Master and the Sonomed for axial length measurement and IOL...

PURPOSE To assess the normal values and the repeatability of the Galilei Dual Scheimpflug Analyzer (GDSA), the biometer IOL Master, and the autokerato/refractometer WAM 5500 in anterior segment examinations. METHODS Eighty-eight eyes from 88 healthy volunteers were prospectively and consecutively recruited. The repeatability was assessed, calculating the intraclass correlation coefficient (IC...

Objective: Cataract surgery with intraocular lens (IOL) implantation tries to get a refractive result nearby to the optic emmetropia. So an accurate IOL power calculation is mandatory, and axial length (AL) measurement is one of the most influential parameter in this calculation. IOL Master is one of the most popular devices to measure AL, which uses the same group refractive index of the lens ...

purpose: to assess hoffer correction factor in measurement of axial length (al) in eyes with phakic iol implants. methods: in this descriptive historical cohort study, axial length was measured by ultrasound (us) and iol master in both phakic and pseudophakic modes in 24 eyes of 14 patients with artisan intraocular lenses (iols) implanted for refractive purposes, hoffer’s suggested formula for ...
