The only Presbyopia Lens with HD-VisionOculentis innovative presbyopia‑correcting LENTIS® Mplus IOL features a completely new approach in multifocal lens technology (patent pending). Based on the refractive principle, the LENTIS® Mplus IOL stands out for an innovative sector‑shaped near‑vision section that offers great advantages compared to the competition: HD-Vision-natural contrast sensitivity, no image jumps and best–corrected distance and near visual acuity. LENTIS Mplus - the only Presbyopia Lens with HD-Vision: Benjamin Franklin's idea from past to present
The Movie: Professor Jorge Alio (Alicante, Spain) has won at this year's ASCRS Film Festival in Boston (April 9 to 14) one of the coveted Oscars. In the category "INSTRUMENTS & DEVICES / IOLs" an adapted version of the Mplus short film shown above called "A brand new technology multifocal IOL: Benjamin Franklin's idea from past to present" convinced the judges and and won the Oscar for "Runner-Up". The film describes the unique operation of the Mplus technology and highlights the benefits of this hightech multifocal intraocular lens. Benjamin Franklin was the first person to conceive that two glasses could be combined into one for the purpose of both distance and near vision. This video presents a background of multifocal technology and how the design of the new MIOL contributes to lens performance. Dr. Jorge Alio demonstrates the implantation technique and presents early clinical results. Alexander Paraker, Director Sales International (Oculentis), took the prize on behalf of Professor Alio, who himself could not attend the award ceremony.
Fig.1.1LENTIS Mplus one-piece, multifocal acryl lens from HydroSmart material with aspheric, asymmetric design comprising a sector shaped near-vision section characterized by seamless transitions between the near and far vision zones Fig.1.2: Data sheet information click here At the DOC 2009 in Nuremberg, the Berlin-based company successfully presented its latest technical milestone – the LENTIS® Mplus IOL - for the first time to a wide expert audience. Compared to the current state-of-the-art in multifocal lens technology, this MIOL stands out for its functional design which is unique in the world and for its optical operating principle (patent pending): An aspheric, asymmetric far-vision zone is combined with a sector‑shaped near-vision zone of + 3.0 diopters allowing for seamless transition between the far and near vision zones. In particular, glare and "image jumps" caused by reflections as often experienced in twilight or in central headlight glare conditions will thus be avoided (Figure 2). "This bifocal lens does give extremely good far, intermidiate and near vision with much less of the problems seen with classic multifocal IOLs." Erik L. Mertens, MD, FEBO; Antwerp Eye Center, Antwerp, Belgium in Ophthalmology Times Europe Jan/Feb 2010 The design principle of the surface-embedded sector segment makes the MIOL independent of the pupil size. This embedded sector segment ensures optimum adjustment of near and distance vision acuity. Another distinctive feature of the lens is that the light - when it hits the transition area to the embedded sector element - will be reflected away from the optical axis. This prevents any superposition of interference/diffraction normally caused by curvature variations on optical surfaces. On the one hand, it will result in a minor loss of light intensity; on the other hand, however, in significantly improved contrast sensitivity. Thanks to this unique patented optic design no ghost or double images are propagated and significantly less glare and/or halo effects appear (Figure 3). "[...] new multifocals such as the LENTIS® Mplus, with rotational asymmetrical optics are important innovations that will bring an important amount of attention during 2010." Jorge L. Alio, MD, PhD; Instituto Oftalmologico de Alicante, Alicante, Spain in Ophthalmology Times Europe Jan/Feb 2010

Fig. 3: (a) Side view of the non rotation-symmetric, multifocal sector lens. The LENTIS® Mplus is constructed by combining two spherical surfaces with different radii; one main surface with a radius R1 and an embedded surface with a radius R2. (b) View on the lens towards the optical axis, topographic view. The embedded surface forms a sector segment in the area of the angle α and the radial area r. (a) and (b) The spherical centers of the two surfaces lie on the Z-axis, i.e. on the optical axis of the sector lens. The vertexes of both surfaces coincide with the origin. Consequently, both principal foci of the lens are on its optical axis. Thus, an image displacement will not be possible.
A multi-center study conducted under the leadership of Prof. Dr. med. G. U. Auffarth of Heidelberg University Eye Clinic analyzing the results obtained with implantation of LENTIS® Mplus IOL in 134 eyes of 79 patients (mean age: 68 ± 12 years) has confirmed the excellent functional outcomes achieved with the MIOL as well as the very high degree of patient satisfaction. No complications were seen in both, unilateral and bilateral implantation. Mean IOL power came to 21.00 ± 2.01 diopters. Three months after surgery, a best corrected distance visual acuity of 0.01 ± 0.14 logMAR was measured. Uncorrected near visual acuity came to 0.08 ± 0.17 logMAR. This averages a distance visual acuity of 0.99 and near visual acuity of 0.83.
In March 2009 the MIOL got the CE marking.
