“…8 In fact, both Muñoz et al 7 and Alió et al [8][9][10] reported that contrast sensitivity in MPlus-implanted patients was similar to that in monofocal IOL-implanted patients at any spatial frequency. [7][8][9][10] Moreover, Alió et al 9,10 reported that eyes implanted with an MPlus MIOL registered higher contrast sensitivity than did eyes implanted with a diffractive MIOL. This feature might also contribute especially for good distance vision, 7 and the immediate visual rehabilitation shown in our results at 1 day postoperatively.…”

“…The aim of that design is to reduce sources of light scattering and aberrations that cause disturbing reflections, halos, and glare; several studies have reported the clinical results of that lens design. [7][8][9][10] Although studies have reported that the postoperative contrast sensitivity outcomes using other MIOLs are worse than those with monofocal IOLs, 11,12 Alió et al 8 reported that the postoperative contrast sensitivity outcomes with MPlus are comparable to those of monofocal IOLs.…”

Purpose To evaluate the postoperative outcomes of cataract eyes complicated with coexisting ocular pathologies that underwent implantation of a refractive multifocal intraocular lens (MIOL) with a surfaceembedded near section. Methods LENTIS MPlus (Oculentis GmbH) refractive MIOLs were implanted in 15 eyes with ocular pathologies other than cataract (ie, six high-myopia eyes with an axial length longer than 28 mm, two fundus albipunctatus eyes, two branch retinal-vein occlusion eyes, four glaucoma eyes (one with high myopia), and two keratoconus eyes). Uncorrected or corrected distance and near visual acuity (VA) (UDVA, UNVA, CDVA, and CNVA), contrast sensitivity, and defocus curve were measured at 1 day and 6 months postoperatively, and each patient completed a 6-month postoperative questionnaire regarding vision quality and eyeglass use. Results Thirteen eyes (87%) registered 0 or better in CDVA and 12 eyes (73%) registered better than 0 in CNVA. Contrast sensitivity in the eyes of all patients was comparable to that of normal healthy subjects. No patient required eyeglasses for distance vision, but three patients (20%) required them for near vision. No patient reported poor or very poor vision quality. Conclusion With careful case selection, sectorial refractive MIOL implantation is effective for treating cataract eyes complicated with ocular pathologies.

“…There are also strategies such as "monovision, " which corrects one eye for far sight and the other eye for near sight, reducing the need for glasses with great success (15,16) . However, despite great improvements in the new generation of lenses, they present side effects, such as intense brightness, formation of halos, and inconsistent intermediate sight (14,15,17) , affecting the daily activities and the quality of life of the users (17,18) .

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. Thus, studies on the visual behavior of these patients may be an important tool to determine the best type of IOL implantation. This study proposed an anamnestic add-on for optimizing the choice of IOL. Methods: We used a camera that automatically takes pictures, documenting the patient's visual routine in order to obtain additional information about the fre quency of distant, intermediate, and near sights. Results:The results indicated an estimated frequency percentage, suggesting that visual analysis of routine photographic records of a patient with cataract may be useful for understanding behavioural gaze and for choosing visual management strategy after cataract surgery, simultaneously stimulating interest for customized IOL manufacturing according to individual needs.

Technical improvements applied to a double-pass setup for performance and cost optimization

Abstract. We have studied the possibility of improving the performance, simplifying, and reducing the cost of a double-pass system by the use of alternative technologies. The system for correcting the spherical correction has been based on a focusable electro-optical lens, and a recording device based on CMOS technology and a superluminescent diode (SLED) light source have been evaluated separately. The suitability of the CMOS camera has been demonstrated, while the SLED could not break the speckle by itself. The final experimental setup, consisting of a CMOS camera and a laser diode, has been compared with a commercial double-pass system, proving its usefulness for ocular optical quality and scattering measurements.
