[Thésaurus Mesh]Réfraction oculaireRésumé : SIGNIFICANCE: The performance of the Eye Refract (Luneau Technology, Chartres, France), a new instrument to perform aberrometry-based automated subjective refraction, has been previously evaluated in healthy subjects. However, its clinical implications in other ocular conditions are still unknown. PURPOSE: The purpose of this study was to evaluate the agreement between the Eye Refract and the traditional subjective refraction, as the criterion standard, in keratoconus patients with and without intracorneal ring segments (ICRSs). METHODS: A total of 50 eyes of 50 keratoconus patients were evaluated, dividing the sample into 2 groups: 27 eyes without ICRS (37.78 ± 9.35 years) and 23 eyes with ICRS (39.26 ± 13.62 years). An optometrist conducted the refraction with the Eye Refract, and another different optometrist conducted the traditional subjective refraction on the same day. Spherical equivalent (M), cylindrical vectors (J0 and J45), and corrected distance visual acuity were compared between both methods of refraction. In addition, Bland-Altman analysis was performed to assess the agreement between both methods of refraction. RESULTS: There were no statistically significant differences (P ≥ .05) between the Eye Refract and the traditional subjective refraction for all the variables under study in either group. Without ICRS, the mean difference and 95% limits of agreement (upper, lower) were −0.20 (+1.50, −1.89) D for M, −0.14 (+1.40, −1.68) D for J0, and +0.05 (+1.23, −1.14) D for J45. With ICRS, these values worsened to −0.62 (+3.89, −5.12) D for M, +0.06 (+2.46, −2.34) D for J0, and −0.02 (+2.23, −2.28) D for J45. CONCLUSIONS: The Eye Refract seems to offer similar results compared with the traditional subjective refraction in keratoconus patients not implanted with ICRS. However, some patients could show abnormal measurements, especially those with ICRS, who should be treated with caution in clinical practice.

[Thésaurus Mesh]Troubles de la réfraction oculaireRésumé : SIGNIFICANCE: The SVOne may prove useful to quickly and easily assess refractive correction needs in community
screenings and low-resource settings, but not all subjects were testable with the device
PURPOSE: This study aimed to compare the SVOne handheld, smartphone-based wavefront aberrometer with a
tabletop autorefractor in identifying refractive errors in elderly subjects.
METHODS: Participants 50 years or older at community eye screenings with visual acuity worse than 20/40 in either eye underwent autorefraction followed by two SVOne trials. Power vectors of right eye data were analyzed.
RESULTS: Of 84 subjects who underwent autorefraction, 67 (79.8%) were successfully autorefracted with the
SVOne, of whom 82.1% (55/67) had a successful repeat reading. Mean M (spherical equivalent) values from tabletop and handheld autorefraction were −0.21 D (95% confidence interval [CI], −0.71 to +0.29 D) and −0.29 D
(95% CI, −0.79 to +0.21 D), respectively (P > .05). Mean astigmatism values from tabletop and handheld devices
were +1.06 D (95% CI, 0.87 to 1.26 D) and +1.21 D (95% CI, 0.99 to 1.43 D), respectively (P > .05). Intraclass
correlation coefficients between devices were 0.95 (95% CI, 0.93 to 0.97) for M, 0.78 (95% CI, 0.66 to 0.86)
for J0, and 0.45 (95% CI, 0.24 to 0.63) for J45 (P < .05 for all). Excellent test-retest correlation between SVOne
measurements was noted for M (Pearson correlation [r] = 0.96; P < .05), but a weaker correlation was noted for
J0 and J45 (r = 0.67 and r = 0.63 [P < .05 for both], respectively).
CONCLUSIONS: The SVOne provided strong agreement for M, with the majority of readings within ±1.00 D of each
other, when compared with the tabletop autorefractor. A weaker but still good correlation was noted for astigmatism. Similar findings were noted when assessing repeatability.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
