When worn for myopia control in children, soft multifocal contact lenses with a +2.50 D add reduced the accommodative response over a 3-year period, but wearing them for more than 4 years did not affect accommodative amplitudes, lag, or facility.
PURPOSE
This study aimed to compare the accommodative response to a 3D stimulus between single-vision, +1.50-D add, and +2.50-D add multifocal contact lens wearers during 3 years of contact lens wear and then to compare accommodative amplitude, lag, and facility between the three groups after an average of 4.7 years of wear.
METHODS
Bifocal Lenses In Nearsighted Kids study participants aged 7 to 11 years old were randomly assigned to wear single-vision, +1.50-D add, or +2.50-D add soft contact lenses (CooperVision, Pleasanton, CA). The accommodative response to a 3D stimulus was measured at baseline and annually for 3 years. After 4.7 years, we measured objective accommodative amplitudes, lead/lag, and binocular facility with ±2.00-D flippers. We compared the three accommodative measures using multivariate analysis of variance (MANOVA), adjusting for clinic site, sex, and age group (7 to 9 or 10 to 11 years).
RESULTS
The +2.50-D add contact lens wearers exhibited lower accommodative response than the single-vision contact lens wearers for 3 years, but the +1.50-D add contact lens wearers exhibited only lower accommodative response than did the single-vision contact lens wearers for 2 years. After adjustment for clinic site, sex, and age group, there were no statistically significant or clinically meaningful differences between the three treatment groups for accommodative amplitude (MANOVA, P = .49), accommodative lag (MANOVA, P = .41), or accommodative facility (MANOVA, P = .87) after an average of 4.7 years of contact lens wear.
CONCLUSIONS
Almost 5 years of multifocal contact lens wear did not affect the accommodative amplitude, lag, or facility of children.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus Mesh]Sensibilité au contrasteMots-clés : lentilles de contact souples multifocales à distance centrale Résumé : SIGNIFICANCE: The contrast sensitivity (CS) function provides a more detailed assessment of vision than visual
acuity. It was found that center-distance multifocal contact lens designs that are increasingly being prescribed
for myopia control reduce distance photopic and mesopic CS in nonpresbyopic patients across a range of spatial
frequencies.
PURPOSE: This study aimed to determine the effect of center-distance multifocal soft contact lenses (MFCLs) on
CS under photopic and mesopic conditions in nonpresbyopic patients.
METHODS: Twenty-five myopic, nonpresbyopic adults were fitted binocularly with three lenses: Biofinity single vision
contact lens (SVCL), Biofinity Multifocal D +2.50 add, and NaturalVue Multifocal in random order. Contrast sensitivity was measured at distance (4 m) under photopic and mesopic conditions and at near under photopic conditions. Log CS by spatial frequency and area under the log contrast sensitivity function (AULCSF) were analyzed between lenses.
RESULTS: Distance photopic CS at each spatial frequency was higher with the SVCL than the MFCLs ( P < .001),
but there was no difference between the MFCLs ( P = .71). Distance mesopic CS from 1.5 to 12 cycles per degree
(cpd) was higher with the SVCL than the MFCLs (all P < .02); however, at 18 cpd, there was no difference in CS
between NaturalVue and the SVCL (P = .76), possibly because of spurious resolution. Photopic AULCSF for the SVCL
was roughly 10% greater than both MFCLs. Contrast sensitivity at near was generally similar between lenses, only slightly
lower with the NaturalVue at 11 and 15.5 cpd, but AULCSF at near was not different between lenses ( P > .05).
CONCLUSIONS: Multifocal contact lenses reduce distance contrast sensitivity under both photopic and mesopic
conditions. There is no clinically significant difference in near CS among all three lenses. These data show that
MFCLs have effects on vision that are not captured by standard high-contrast visual acuity testing.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

Children are being fitted at younger ages with soft contact lenses for myopia control. This 3-year investigation of adverse events related to contact lens wear in 7- to 11-year-old participants helps optometrists understand what to expect when fitting children with soft contact lenses.
PURPOSE
The purpose of this article is to report the frequency and type of ocular and nonocular adverse events related to soft contact lens wear in children.
METHODS
Seven- to 11-year-old children wore soft contact lenses for 3 years. Adverse events were defined by a slit-lamp examination finding of grade 3 or worse; parental report of a clinically meaningful change (determined by the examiner) in eyes, vision, or health; or a clinically meaningful response (determined by examiner) to a symptom checklist. Adverse events were categorized and reported by examiners and finalized by the Executive Committee. The presence or absence of an infiltrate and a list of diagnoses was determined at the conclusion of the study.
RESULTS
The 294 participants wore their contact lenses 73.0 ± 26.5 hours per week, and 220 (74.8%) encountered at least 1 adverse event. Of the 432 adverse events, 75.2% were ocular, and 24.8% were nonocular. Contact lens wear was probably or definitely related to 60.6% of the ocular and 2.8% of the nonocular adverse events. None of the ocular adverse events were serious or severe or caused permanent contact lens discontinuation. The corneal infiltrate incidence was 185 cases per 10,000 patient-years of wear (95% confidence interval, 110 to 294). The incidence of moderate ocular adverse events that were definitely or probably related to contact lens wear was 405 cases per 10,000 patient-years of wear (95% confidence interval, 286 to 557).
CONCLUSIONS
The adverse events experienced by 7- to 11–year-old myopic children rarely required meaningful treatment and never led to permanent discontinuation of contact lens wear or loss of best-corrected vision.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus HELB]:Optique:Lentilles multifocalesRésumé : SIGNIFICANCE: With multifocal contact lenses (MFCLs) used for myopia control, questions remain regarding visual performance. Information from nonpresbyopic patients provides insight into how MFCLs affect visual acuity
and reading performance.
PURPOSE: The purpose of this study was to examine the visual performance of center-distance MFCLs in
nonpresbyopic adults under different illumination and contrast conditions compared with a single-vision contact
lens (SVCL).
METHODS: Twenty-five adult subjects were fit with three different lenses (CooperVision Biofinity D MFCL +2.50
add, Visioneering Technologies NaturalVue MFCL, CooperVision Biofinity sphere). Acuity and reading performance
were evaluated.
RESULTS: A statistically significant difference in high-contrast distance acuity was observed (Biofinity, −0.18 ± 0.06;
Biofinity MFCL, −0.14 ± 0.08; NaturalVue MFCL, −0.15 ± 0.03; repeated-measures [RM] ANOVA, P = .02). Under
mesopic, high-contrast conditions, MFCLs performed worse than SVCLs (Biofinity, −0.05 ± 0.091; Biofinity MFCL,
+0.03 ± 0.09; NaturalVue MFCL, +0.05 ± 0.091; RM-ANOVA, P < .0001). Under low-contrast conditions, MFCLs performed one line worse in photopic lighting and two lines worse under mesopic conditions (RM-ANOVA, P < .0001).
Glare reduced acuity by 0.5 logMAR for all lenses (RM-ANOVA, P < .001). A statistically significant difference in near
acuity was observed (RM-ANOVA, P = .02), but all lenses achieved acuity better than −0.1 logMAR (Biofinity,
−0.16 ± 0.06; Biofinity MFCL, −0.17 ± 0.04; NaturalVue MFCL, −0.13 ± 0.08). Reading performance in words per
minute (wpm) was worse with MFCLs (Biofinity MFCL, 144 ± 22 wpm; NaturalVue MFCL, 150 ± 28 wpm) than with
SVCLs (156 ± 23 wpm; RM-ANOVA, P = .02) regardless of letter size (RM-ANOVA, P = .13). No difference in acuity
between the MFCLs was detected (RM-ANOVA: all, P > .05).
CONCLUSIONS: Multifocal contact lenses perform similarly to SVCLs for high-contrast targets and display reduced
low-contrast acuity and reading speed. Practitioners should recognize that high-contrast acuity alone does not describe MFCL visual performance.
