“…The largest published case series of bilateral implantation of the Lentis Mplus LS-312 multifocal IOL by Venter et al 9 found excellent distance and near visual acuity in patients after placement of the near segment inferiorly as per the manufacturer's instructions. Incidental rotation of the IOL away from its intended axis has been found to be well tolerated, 9,17 spurring interest in the possibility of deliberate rotation of the near add segment into other positions to gain certain clinical refractive advantages.…”

“…Incidental rotation of the IOL away from its intended axis has been found to be well tolerated, 9,17 spurring interest in the possibility of deliberate rotation of the near add segment into other positions to gain certain clinical refractive advantages. One suggestion is to rotate the near add superotemporally to maximize the theoretical beneficial effect of displacing unwanted near segment coma-induced glare without introducing further unwanted photic symptoms.…”

“…5,6 The new Lentis Mplus LS-312 multifocal IOL (Oculentis GmbH) corrects presbyopia through use of a refractive design; however, it incorporates a new approach in multifocal IOL technology by virtue of its sector-shaped near vision section. 7,8 This IOL has been shown to provide high-quality vision with high patient tolerance of abnormal visual phenomena 9 and less loss of contrast sensitivity. 7,10 The asymmetric nature of this IOL enables the near segment to be placed in various rotational positions.…”

“…2 In addition, this design allows the reduction of the sources of scattering, halos, and glare. 21 Aberrometry is an important clinical tool for objective diagnosis and eye examination. Here, it is shown that the direct application of conventional and commercial wavefront sensors is not appropriate for accurate estimation of the aberrations in patients implanted with the rotationally asymmetric refractive multifocal IOLs.…”

ataract is successfully treated by replacement of the crystalline lens with an intraocular lens (IOL). Monofocal IOLs are preferably set for far vision and reading glasses are used for near vision. The dependency on glasses after cataract surgery can be eliminated with the help of multifocal IOLs that provide multiple foci and thereby enable functional simultaneous vision at far, intermediate, and near distances. Most designs of multifocal IOLs are diffractive, refractive, or hybrid. 1A rotationally asymmetric refractive multifocal IOL design has gained popularity in the past decade. This design provides two distinct foci with its two definite correcting zones for far and near vision. In general, there is a smooth transition between the two zones. The Lentis Mplus IOL (Oculentis GmbH, Berlin, Germany) is based on this design and has demonstrated good near and distance visual outcomes and good contrast sensitivity.2 The presence of a large magnitude intraocular primary coma has been reported in patients implanted with this multifocal IOL, which is usually attributed to its vertical asymmetric optical geometry. 3,4 In addition, it is believed that the presence of this optical defect allows an extended depth of focus that would grant adequate vision at various distances. On the other hand, it is assumed that this additional coma causes C ABSTRACT 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. The method was tested using ray tracing optical simulations in a computer eye model virtually implanted with the Lentis Mplus IOL, with a generic cornea or with anterior segment geometry obtained from custom quantitative spectral-domain optical coherence tomography in a real patient. The method was applied to laser ray tracing aberrometry data at near and far fixation obtained in a patient implanted with the Lentis Mplus IOL. RESULTS:Higher order aberrations evaluated from simulated and real retinal spot diagrams following the new reconstruction approach matched the nominal aberrations (approximately 98%). Previously reported primary vertical coma in patients implanted with this IOL lost significance with the application of the proposed reconstruction.CONCLUSIONS: Custom analysis of ray tracing-based retinal spot diagrams allowed decoupling of the true higher order aberrations of the patient's eye from the power pupillary distribution of a rotationally asymmetric multifocal IOL, therefore providing the appropriate phase map to accurately evaluate through-focus optical quality.[J Refract Surg. 20...

“…There have been different multifocal designs, including diffractive bifocal, 1 apodized diffractive, 2 trifocal, refractive, zonal refractive, 1 rotational asymmetric refractive, 3 and accommodating IOLs in which the optic or optics need to move to achieve accommodation. 4 Bifocal diffractive apodized IOLs have a circular pattern on the optic surface, which allows for diffraction of incoming light into two main distinct foci.…”

o r I g I n A L A r t I C L e ultifocal intraocular lenses (IOLs) were introduced in cataract surgery to address the problem of loss of accommodation following lensectomy and implantation of a monofocal IOL. There have been different multifocal designs, including diffractive bifocal, 1 apodized diffractive, 2 trifocal, refractive, zonal refractive, 1 rotational asymmetric refractive, 3 and accommodating IOLs in which the optic or optics need to move to achieve accommodation. 4 Bifocal diffractive apodized IOLs have a circular pattern on the optic surface, which allows for diffraction of incoming light into two main distinct foci. One focus is for distance vision and the secondary focus is for near vision. The diffraction patterns distribute the light to both foci with loss of energy; approximately 18% of light is directed outside the far and near focal points.2 As a result of multiple foci occurring in the eyeball at the same time and interfering with one another, the contrast sensitivity for both far and near foci decreases. 5In apodized diffractive IOLs, the far focus is dominant and receives more light, whereas the near focus receives less light. 2The patterns of the apodization can differ and not only allow changes in depth of focus with relation to the intensity of light distributed between the far and the near foci, but also changes in induced halos, contrast, and quality of vision with relation to the pupil size as a function of light intensity as part of the accommodative triad response. 6,7 M ABSTRACT PURPOSE: To evaluate differences in straylight between eyes implanted with a hydrophilic multifocal IOL (Seelens MF; Hanita Lenses, Hanita, Israel) and a hydrophobic multifocal IOL (SN6AD1; Alcon Laboratories, Inc., Fort Worth, TX). METHODS:In a prospective cohort study, routinely obtained straylight measurements (C-Quant; Oculus Optikgeräte, Wetzlar, Germany) 3 months after standard phacoemulsification for either cataract or refractive lens procedures were compared. Patients were implanted with either the SeeLens MF IOL or the SN6AD1 IOL. Postoperative straylight values, visual acuity, and refractive outcomes were compared. RESULTS:The SeeLens MF IOL was implanted in 84 eyes and the SN6AD1 IOL in 79 eyes. The difference in straylight was 0.08 (P = .01), with the SeeLens MF IOL having less straylight. Postoperative CDVA was logMAR -0.03 ± 0.06 in the SeeLens MF group, and logMAR -0.02 ± 0.08 in the SN6AD1 group. Mean postoperative refraction was +0.01 ± 0.43 and +0.06 ± 0.35 D, respectively. CONCLUSIONS:The Seelens MF IOL showed a straylight of log(s) 0.08 lower than the SN6AD1 IOL. In terms of spherical equivalent and visual acuity the lenses performed equally. More study will aid in understanding the causes and clinical impact of this difference.[J Refract Surg. 2015;31(11):746-751.]
