Purpose/Aim: To evaluate the impact of ocular parameters on the visual performance achieved with the multifocal intraocular lens (IOL) Bi-Flex M 677MY. MATERIALS AND METHODS: 26 subjects were included in the current study. Several physiological variables were retrieved from the 3-month follow-up visit, including pupil diameter and distance from pupil center to the vertex normal of the anterior cornea (µ). These variables were also obtained in the preoperative visit. Binocular and monocular visual acuity defocus curves were measured at 1 and 3 months after surgery, respectively...

Objectives: To assess the visual outcomes in patients who underwent cataract surgery with multifocal intraocular lens (IOL) implantation using a "mix and match" approach. Materials and Methods: Twenty patients (40 eyes) were involved in this prospective, nonrandomized study. Refractive multifocal IOLs (ReZoom NXG1) were implanted in patients' dominant eyes and diffractive multifocal IOLs (Tecnis ZMA00) were implanted in their non-dominant eyes. Monocular and binocular uncorrected distance, intermediate and near visual acuity (logMAR), and contrast sensitivity levels were measured at 1, 3, and 6 months after cataract surgery...

Purpose: Multifocal intraocular lenses (IOLs) can be associated with unwanted visual phenomena, including halos. Predicting potential for halos is desirable when designing new multifocal IOLs. Halo images from 6 IOL models were compared using the Optikos modulation transfer function bench system and a new high dynamic range (HDR) system. Materials and methods: One monofocal, 1 extended depth of focus, and 4 multifocal IOLs were evaluated. An off-the-shelf optical bench was used to simulate a distant (>50 m) car headlight and record images...

IMPORTANCE: Studies evaluating the clinical benefits of intraoperative aberrometry (IA) in cataract surgery are limited. BACKGROUND: The study was designed to determine whether IA improved clinical outcomes of post-laser in situ keratomileusis (LASIK) cataract surgery with different intraocular lenses (IOLs) implanted. DESIGN: A retrospective chart review of clinical outcomes from one surgeon at one surgical centre was conducted. It included post-LASIK cataract surgeries where IA was used for the confirmation of IOL power, with either a distant-dominant multifocal IOL or a monofocal IOL implanted...

PURPOSE: To investigate the tilt and decentration of multifocal intraocular lenses (MfIOLs) implanted in myopic eyes. DESIGN: A prospective cohort study. METHODS: Twenty-eight myopic eyes and 56 emmetropic eyes were evaluated. Phacoemulsification with Tecnis ZMB00 MfIOL (Abbott Medical Optics, Santa Ana, California, USA) implantation was performed. At 1 year post-surgery, routine postoperative examinations were performed, and tilt and decentration of the MfIOLs, high-order aberrations, and modulation transfer function (MTF) were evaluated using the OPD-Scan III aberrometer (Nidek Co, Ltd, Gamagori, Japan)...

REVIEW
Liberdade C Salerno, Mauro C Tiveron, Jorge L Alió
The multifocal intraocular lenses (IOLs) available are often able to restore visual function and allow spectacle independence after their implantation with great levels of patient satisfaction. The factors associated with the postoperatory success include the careful selection of the patient, the knowledge about the IOLs' design, and their visual performance added to the proper surgical technique and management of possible complications as demonstrated by the evidence available.

In existing designs of intraocular lenses (IOLs), optical outcomes are compromised even after perfectly executed surgery. The reason for this is misalignment of optical axis of the eye and its visual axis. There is a need to design an IOL which compensates for this misalignment and hence enhances the optical outcomes of cataract surgery. The present innovation attempts to fulfill this unmet need and optimizes optical outcomes of all IOLs of different optical profiles - spherical, aspheric, toric, and multifocal...

Objectives In customised patient care, it is important to know the optical quality of different intraocular lenses (IOL). In this study, the optical quality of three segmental intraocular lenses were compared. Materials and Methods The LENTIS Comfort LS-313 MF15, LENTIS Mplus X LS-313 MF30 and LENTIS High Add IOL LS-313 MF80 (Oculentis, Berlin, Germany) with a far power of + 21 D were analysed at the optical bench OptiSpheric IOL PRO (Trioptics GmbH, Wedel, Germany). The lenses have almost the same optical design but differ in the power of the near segment...
