    Abstract Introduction: To evaluate and compare the clinical outcomes of two toric presbyopia-correcting intraocular lenses (IOLs).
    Methods: Non-randomized prospective comparative study including 86 eyes of 51 patients (age 43-83 years) that underwent cataract surgery with implantation of one of the following two IOLs: TECNIS Toric Synergy (Johnson & Johnson Vision) (Synergy group) or AT LISA tri toric 939MP (Carl Zeiss Meditec) (ATLISA group). Visual and refractive outcomes were evaluated during a 6-month follow-up.
    Results: At 6 months after surgery, all eyes achieved uncorrected distance visual acuity 20/25 or better in both groups, whereas 96.2% and 100% of eyes achieved uncorrected near visual acuity (UNVA) 20/25 or better in the ATLISA and Synergy groups, respectively. All eyes achieved postoperative mesopic UNVA 20/30 or better in both IOL groups; 96.2% and 100% of eyes had a manifest cylinder ≤ 0.50 D at 6 months in ATLISA and Synergy groups, respectively. Mean magnitude of error was 0.04 ± 0.20 and - 0.04 ± 0.09 D in ATLISA and Synergy groups, respectively (p = 0.05). In the defocus curve, significant differences were found between IOL groups for most of distance-corrected visual acuities, except those corresponding to defocus of 0 D (p = 0.268) and - 1 D (p = 0.361).
    Conclusions: The two toric presbyopia-correcting IOLs evaluated provide an efficacious astigmatic correction combined with a successful distance, intermediate and near visual rehabilitation. The visual performance seems to be better for most visual demands with the TECNIS Toric Synergy IOL, especially for distances closer than 40 cm.

    Abstract Purpose: To analyze and report the long-term outcomes in terms of efficacy and safety of eyes implanted with the spherical version of a foldable iris-fixated phakic intraocular lens (pIOL) for the correction of myopia.
    Methods: Retrospective analysis of the results of 56 eyes of 32 patients (age, 19-45 years) who underwent implantation of the spherical model of the Artiflex pIOL (Ophtec B.V., Groningen, The Netherlands) for the correction of myopia. Visual, refractive, biometric, intraocular pressure (IOP) and corneal endothelial changes were evaluated during a long-term follow-up: 2, 7, 10 and 12 years for more than 50, 30, 20 and 10 eyes, respectively.
    Results: At 4 weeks postoperatively, a significant reduction of manifest sphere and spherical equivalent (SE), with a significant improvement of uncorrected distance visual acuity were found (all p < 0.001). No significant changes were found during the rest of follow-up in sphere (p ≥ 0.072). The percentage of eyes with SE within ± 1.00 D was over 83% during the whole follow-up. A non-significant trend to IOP increase was observed at 4 weeks postoperatively (p = 0.530), with a significant reduction at 1 year after (p = 0.039) and no significant changes during the rest of follow-up (p = 0.180). There was a significant reduction of anterior chamber depth at 4 weeks after surgery (p < 0.001), with no significant changes during the following 9 years of follow-up (p = 0.118). However, an additional significant decrease of this parameter was observed between 10 and 13 years after surgery (p = 0.027). Mean endothelial cell loss changed from 2.01 ± 4.49% at 4 weeks after surgery to 9.11 ± 2.24% at the end of the follow-up. No complications were reported during the follow-up.
    Conclusions: Myopia correction with the Artiflex pIOL is an effective and safe procedure in the long term.

    Abstract Purpose: To investigate by using computational simulations the optical impact of the change in the vault of two geometries of scleral contact lenses (SCLs).
    Methods: Ray-tracing simulations were performed using specialized software in three eye models with different levels of primary SA (6 mm pupil). Two different geometries of SCL were used in such simulations characterized by the conic constants of the anterior surface of the lens (K1, -0.1 and -0.3). Likewise, the fitting of the SCL was simulated for different vaults (50-250 µm). The impact on the quality of the images through the eye models was assessed by analyzing the modulation transfer function (MTF) at different spatial frequencies (10 Lp/mm, 30 Lp/mm, and 50 Lp/mm). This impact was not only simulated for a distant object, but also for intermediate and near objects (vergence demands from 0.00 to 3.00 D). All these optical simulations were performed assuming a centered SCL, but also assuming a downward vertical decentration of 0.5 mm.
    Results: The thinnest vault (50 µm) provided the best ocular optical quality in all three eye models for low vergence demands. For medium and high vergence demands, Lens 1 (K1 = -0.3, K2 = -0.4) resulted in a considerable improvement in optical quality in Eye 2 (C
    Conclusions: Changes in the vault of a SCL have an impact on the optical quality achieved for different vergence demands independently on the level of SA of the eye in which it is fitted. The clinical relevance of such impact should be investigated further.

    Abstract Purpose: To summarize and analyze critically the scientific evidence focused on the effectiveness of the use of hydrophilic contact lenses (HCLs) in myopia control, as well as their impact on visual quality and the involvement on the accommodative and binocular function.
    Methods: This systematic review was developed selecting all original studies which evaluated HCLs for myopia control with follow-up of at least 1 year. Eligible randomized controlled trials (RCTs) were retrieved from PubMed MEDLINE and Scopus. Methodological quality of the studies was assessed using the Critical Appraisal Skills Programme (CASP) for RCTs.
    Results: The search provided a total of 276 articles, selecting 13 according to the inclusion and exclusion criteria. The majority of studies evaluating the effectiveness of HCL showed a good efficacy in myopia progression, providing a good quality of vision. The quality of these studies was found to be suitable according to the CASP tool. The accommodative and binocular function with these lenses was evaluated in few studies, reporting a trend to an increase in the accommodative response and exophoria in near vision, while maintaining good level of stereopsis. Aberrometry and pupillometry were only studied in one trial, in which the authors did not find changes in these variables after the use of a myopia control HCL.
    Conclusions: There is a strong evidence about the effectiveness of different HCLs designs for slowing down myopia progression in children, providing all of them good levels of visual quality. However, there is still poor evidence about changes in accommodation and binocular function, as well as in pupil size and aberrometry with myopia control HCLs, being necessary more studies focused on this issue.

    Abstract Purpose: Alzheimer's disease (AD) is a neurodegenerative disease generating a progressive neuronal loss as well as cognitive deficiencies. This disease can be accompanied by ocular manifestations, including alterations in ocular motility and visual perception. The aim of the current review article was to collect all the information about these alterations and to analyze if there is scientific evidence supporting the potential use of these changes as biomarkers of the disease.
    Methods: A bibliographic search was performed using two different databases, Pubmed and Google Scholar, as well as a search of material in non-peer reviewed journals about Alzheimer's and Neurology. A total of 227 articles were found in the initial search, but only 76 were included considering their relevance according to the purpose of the reviewResults: This narrative review describes the findings obtained in this area to this date, confirming that deficiencies in saccades is the most common condition among AD patients. Furthermore, other visual alterations have also been reported in these patients, including a compromise of visual acuity and contrast sensitivity, fluctuations of colour vision, stereopsis impairment and visual field losses. Likewise, other complex visuo-spatial and visuo-perceptual impairments can be present. More studies are still needed to understand better what type of changes occurs in ocular alignment, binocularity, and fixation pattern in AD patients.
    Conclusions: AD is associated to visual perception and ocular motility alterations. All the scientific information found in this review should be considered as a guide for designing future studies and to define adequate clinical protocols for the visual evaluation of patients with AD, considering the cognitive limitations that are normally present in this type of patients.
