“…Besides VA, accommodation and binocular evaluation, an analysis of the impact of the wearing of the EDOF CL evaluated on ocular aberrations and perception of photic phenomena was also performed. To date, few studies have evaluated changes in ocular aberrations with CLs for myopia control [17,20,38,39]. In our sample, a significant increase was found with the CL wear in HOA RMS, primary coma RMS, primary spherical aberration Zernike term and secondary astigmatism RMS for both 3 and 5 mm pupils, but always reaching values within the range of variability of ocular aberrations defined for the healthy population using the same multi-diagnostic platform [40].…”

“…Aspheric designs reported a mild decrease in contrast sensitivity, a 0.28 ± 0.40 D reduction in accommodative response and a significant increase in third and fourth aberrations (p < 0.05) [15]. The CL based on concentric rings involved a controlled increase in aberrations and a reduction in contrast sensitivity while maintaining a suitable visual acuity [18][19][20]. The use of MFCLs with high additions designed for myopia progression control was found to reduce peripheral contrast sensitivity but without impairment of central contrast sensitivity [22].…”

“…However, these studies did not evaluate the visual function with CLs. Later, specific multifocal CLs were designed for myopia control using aspheric designs [16,17], patterns of concentric rings [18][19][20] or complex designs based on the combination of an aspherical anterior surface with a double inverse geometry design on the back [21]. Aspheric designs reported a mild decrease in contrast sensitivity, a 0.28 ± 0.40 D reduction in accommodative response and a significant increase in third and fourth aberrations (p < 0.05) [15].…”

This pseudo-experimental, prospective, and longitudinal pilot study was conducted to characterize the optical and visual changes occurring in the short-term wear of a hydrophilic contact lens (CL) based on extended focus technology (EDOF). A total of 30 eyes of 15 children (age, 6–16 years) were fitted with the EDOF CL Mylo (Mark’ennovy Care SL), performing an exhaustive follow-up for one month evaluating changes in visual acuity (VA), accommodation, binocularity, ocular aberrometry, visual quality, pupillometry, keratometry and biometry. Far and near VA with the CL improved progressively (p < 0.001), obtaining mean final binocular values of −0.08 ± 0.01 and −0.07 ± 0.01 LogMAR, respectively. There was a mean reduction in the accommodative LAG of 0.30 D (p < 0.001), without associated alterations in the magnitude of the phoria and fusional vergences (p ≥ 0.066). A controlled but statistically significant increase (p ≤ 0.005) of ocular high order aberration (HOA) root mean square (RMS), primary coma RMS, primary spherical aberration Zernike term and secondary astigmatism RMS was found with the CL wear. In conclusion, the EDOF CL evaluated provides adequate visual acuity and quality, with associated increased of several HOAs and a trend to reduction in the accommodative LAG that should be confirmed in future studies.

“…Therefore, clinicians must be not only aware that DFCL designs can help to reduce myopia progression but also that the reduction of objective quality of vision during DFCL wear might be clinically relevant. Finally, Lopes-Ferreira et al 33 evaluated HOAs RMS values for a 5-mm pupil size after 24 months of DFCL wear. They did not find differences between DFCL and distance SV spectacle correction patients when HOAs were measured without any optical compensation.…”

Objective: The purpose of this study was to assess the visual performance and monochromatic higher-order aberrations (HOAs) obtained while wearing a MiSight dual-focus (DF) contact lenses (CL) in comparison with a single-vision contact lens (SVCL). Methods: A randomized, double-masked, cross-over study was performed. Participants were fitted with a DFCL and a SVCL composed of the same material (omafilcon A) and parameters. Logarithm of the Minimum Angle of Resolution high-contrast (100%) and low-contrast (10%) visual acuity (VA) and contrast sensitivity (CS) for 3, 6, 12, and 18 cycles per degree were measured. Higher-order aberrations were also evaluated using a Hartmann–Shack aberrometer with the CLs on. Results: Twenty-four subjects (21 females and 3 males) with a mean age of 21.9±1.9 years (range: 18–27) were included. Low-contrast VA was significantly lower with the DFCL regarding the SVCL design (0.39±0.23 vs 0.25±0.18, P=0.002). However, there were no differences in high-contrast VA between both CLs (−0.03±0.10 vs −0.09±0.14, P=0.187). Contrast sensitivity was lower with the DFCL under all spatial frequencies (P≤0.048). Second-, third-, fourth-, and fifth-order aberrations were significantly (P<0.001) higher for the DFCL. There were also significant differences between DFCL and SVCL in defocus (0.87±0.28 vs 0.16±0.35, P<0.001), oblique trefoil (−0.16±0.27 vs −0.01±0.08, P=0.005), vertical coma (0.13±0.17 vs 0.00±0.08, P=0.002), and spherical aberration (0.09±0.11 vs −0.02±0.05, P=0.002). Conclusion: Visual performance for detecting low-contrast targets is reduced when wearing MiSight DFCL compared with a SVCL with the same material. The main reason might be the induction of second-order and HOAs by the DFCL design.

Background Myopia is a common refractive error, where elongation of the eyeball causes distant objects to appear blurred. The increasing prevalence of myopia is a growing global public health problem, in terms of rates of uncorrected refractive error and significantly, an increased risk of visual impairment due to myopia‐related ocular morbidity. Since myopia is usually detected in children before 10 years of age and can progress rapidly, interventions to slow its progression need to be delivered in childhood. Objectives To assess the comparative efficacy of optical, pharmacological and environmental interventions for slowing myopia progression in children using network meta‐analysis (NMA). To generate a relative ranking of myopia control interventions according to their efficacy. To produce a brief economic commentary, summarising the economic evaluations assessing myopia control interventions in children. To maintain the currency of the evidence using a living systematic review approach. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register), MEDLINE; Embase; and three trials registers. The search date was 26 February 2022. Selection criteria We included randomised controlled trials (RCTs) of optical, pharmacological and environmental interventions for slowing myopia progression in children aged 18 years or younger. Critical outcomes were progression of myopia (defined as the difference in the change in spherical equivalent refraction (SER, dioptres (D)) and axial length (mm) in the intervention and control groups at one year or longer) and difference in the change in SER and axial length following cessation of treatment ('rebound'). Data collection and analysis We followed standard Cochrane methods. We assessed bias using RoB 2 for parallel RCTs. We rated the certainty of evidence using the GRADE approach for the outcomes: change in SER and axial length at one and two years. Most comparisons were with inactive controls. Main results We included 64 studies that randomised 11,617 children, aged 4 to 18 years. Studies were mostly conducted in China or other Asian countries (39 studies, 60.9%) and North America (13 studies, 20.3%). Fifty‐seven studies (89%) compared myopia control interventions (multifocal spectacles, peripheral plus spectacles (PPSL), undercorrected single vision spectacles (SVLs), multifocal soft contact lenses (MFSCL), orthokeratology, rigid gas‐permeable contact lenses (RGP); or pharmacological interventions (including high‐ (HDA), moderate‐ (MDA) and low‐dose (LDA) atropine, pirenzipine or 7‐methylxanthine) against an inactive control. Study duration was 12 to 36 months. The overall certainty of the evidence ranged from very low to moderate. Since the networks in the NMA were poorly connected, most estimates versus control were as, or more, imprecise than the c...
