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...

BACKGROUND: Good unaided distance visual acuity (VA) is now a realistic expectation following cataract surgery and intraocular lens (IOL) implantation. Near vision, however, still requires additional refractive power, usually in the form of reading glasses. Multiple optic (multifocal) IOLs are available which claim to allow good vision at a range of distances. It is unclear whether this benefit outweighs the optical compromises inherent in multifocal IOLs. OBJECTIVES: To assess the visual effects of multifocal IOLs in comparison with the current standard treatment of monofocal lens implantation...

COMPARATIVE STUDY
Jens Schrecker, Achim Langenbucher
PURPOSE: To compare the long-term results of a secondary sulcus-placed, multifocal add-on intraocular lens (IOL) with those of a multifocal IOL implanted in the capsular bag. METHODS: In this prospective clinical trial, 30 pseudophakic eyes were treated with a multifocal add-on IOL and 30 cataractous eyes with a standard multifocal IOL. The main outcome measures comprised manifest refraction, visual acuity, defocus curves, and contrast sensitivity. Patients who had bilateral implantation of the same lens type were asked to complete a questionnaire...

REVIEW
Steven Greenstein, Roberto Pineda
We performed a literature review comparing multifocal intraocular lens (IOL) implantation with pseudophakic monovision to treat presbyopia. Multifocal IOLs utilize refractive or diffractive principles to treat both distance and near vision, with a single lens implant. Monovision uses traditional monofocal lens implants to treat the dominant eye for emmotropia, and the non-dominant eye for myopia. This planned anisometropia is designed to enhance intermediate or near vision. Generally, distance vision was similar with both types of lens implantation, near vision was better with multifocal IOLs, and intermediate vision appeared to be better in the monovision group...

REVIEW
A Liekfeld, D Befurt
PURPOSE: Many different models and types of special intraocular lenses (IOL) are now available for refractive lens surgery. In particular, toric and multifocal IOL need specific conditions to achieve satisfactory results. For multifocal IOL, many models with different optical principles are available. For optimal individual patient-centred care, it is necessary to consider several different options. With special refractive lenses, the principle objective for the patients is to become less dependent on glasses...

PURPOSE: Cataract is the main cause of blindness, affecting 18 million people worldwide, with the highest incidence in the population above 50 years of age. Low visual acuity caused by cataract may have a negative impact on patient quality of life. The current treatment is surgery in order to replace the natural lens with an artificial intraocular lens (IOL), which can be mono- or multifocal. However, due to potential side effects, IOLs must be carefully chosen to ensure higher patient satisfaction...

In this paper, the authors try to motivate their preference for implanting AT.Lisa Multifocals from all other premium IOL's from the market. It is emphasized, through clinical examples, that their choice comes after a long experience with this type of mul- tifocals IOL's. We make a short presentation of this particular type of MIOL's with their good but also weak points and try to motivate our decision to change from other types. We present the steps that each patient has to follow in our clinic prior to surgery itself, stressing out the idea that the discussion with the patient is very important in taking a decision regarding the implantation of a Premium IOL...
