.... In an optical bench analysis, we compare spherical (A), aberration correcting (B), and specific aspherical lenses (C) in terms of impact of decentration and tilt on the modulation transfer function as well as the simulated overall quality with USAF test targets. Material and Methods: The OptiSpheric IOL PRO2...

...Fan Zhang; Jian Zhang; Wei Li; Lin Zhou; Di Feng; Haixia Zhang; Wei Fang; Ran Sun; Zhicheng Liu Purpose: To evaluate which ocular axis, the corneal topographic axis (CTA), pupillary axis (PA) or line of sight (LOS), for measuring the tilt and decentration of intraocular lens (IOL) is most relevant...

.... Subgroups of emmetropic, myopic and hyperopic eyes were defined according to IOL power calculation. Anterior chamber depth (ACD) measurements were performed with an AC-Master. Tilt and decentration of the IOL were measured with a Purkinje meter. Follow-up assessments were performed 1 h, 3 weeks and 3 months...

...J.G. Sivak; R.O. Kreuzer; T. Hildebrand Concern has been expressed in the literature regarding the frequency and amount of astigmatism found in patients with intraocular lens implants. Postoperative tilting of the implants is one suggested cause. We have measured the effect of tilt on focal length...
