Fast tunable lenses allow an effective design of a portable simultaneous vision simulator (SimVis) of multifocal corrections. A novel method of evaluating the temporal profile of a tunable lens in simulating different multifocal intraocular lenses (M-IOLs) is presented. The proposed method involves the characteristic fitting of the through-focus (TF) optical quality of the multifocal component of a given M-IOL to a linear combination of TF optical quality of monofocal lenses viable with a tunable lens. Three different types of M-IOL designs are tested, namely: segmented refractive, diffractive and refractive extended depth of focus...

Presbyopia-treating intraocular lenses (IOLs) are now widely available and offer high predictability at all distances, better visual outcomes, and high patient satisfaction. In most patients, the same multifocal IOL is implanted bilaterally. In certain circumstances, such as during complex surgeries, it is important to be prepared with a backup plan to maintain surgical expectations. We report 3 patients who had femtosecond laser-assisted cataract surgeries in both eyes. The complicated eye had implantation of a bifocal IOL and the fellow eye of a trifocal IOL...

The occurrence of multifocal intraocular lens (MIOL) is known as an important period in the development of cataract surgery, which can provide a simultaneous vision without the use of spectacles or contact lenses. However, in the current stage, MIOL implantation may also lead to decreased visual acuity and increased risk of photic phenomena, thus in some instance a second procedure to exchange the MIOL is necessary. Optimizing visual outcomes of MIOL implantation and controlling adverse effects has become the focus for ophthalmologists...

PURPOSE: Standard evaluation of aberrations from wavefront slope measurements in patients implanted with a rotationally asymmetric multifocal intraocular lens (IOL), the Lentis Mplus (Oculentis GmbH, Berlin, Germany), results in large magnitude primary vertical coma, which is attributed to the intrinsic IOL design. The new proposed method analyzes aberrometry data, allowing disentangling the IOL power pupillary distribution from the true higher order aberrations of the eye. METHODS: The new method of wavefront reconstruction uses retinal spots obtained at both the near and far foci...

Multifocal intraocular lenses (MfIOLs) are increasingly used in the management of pseudophakic presbyopia. After MfIOL implantation, most patients do not need spectacles or contact lenses and are pleased with the result. Complications, however, may affect the patient's quality of life and level of satisfaction. Common problems with multifocal lenses are blurred vision and photic phenomena associated with residual ammetropia, posterior capsule opacification, large pupil size, wavefront anomalies, dry eye, and lens decentration...
