[Thésaurus Mesh]Réfraction oculaireMots-clés : biomètre optique biométrie oculaire Réfraction oculaire Résumé : SIGNIFICANCE: This study provides information about the repeatability of Myopia Master (Oculus, Wetzlar, Germany) and its agreement with Lenstar LS900, which might be useful for the practitioners involved in myopia management. PURPOSE: Myopia Master is a new optical biometer that measures ocular biometry and refractive error. The purpose of this study was to assess its repeatability (intrasession and short-term intersession) and its agreement with Lenstar LS900 for the measurement of axial length and corneal curvature. METHODS: A total of 304 participants including 254 children (mean ± standard deviation age, 13.7 ± 1.6 years) and 50 adults (24 ± 2.9 years) underwent measurements on Myopia Master and Lenstar LS900 to obtain axial length, flat K, and steep K. On a subset of 30 participants, measurements were obtained with Myopia Master in two sessions that were spread over 10 minutes to assess the short-term intersession repeatability. RESULTS: The mean standard deviation of Myopia Master in the measurement of axial length in the total sample was 0.01 mm for intrasession, when the best three measurements were considered. The short-term intersession mean standard deviation for axial length, flat K, and steep K was 0.06 mm, 0.15 D, and 0.21 D, respectively. There were statistically significant differences in mean values of axial length (−0.04 ± 0.06 mm), flat K (−0.07 ± 0.15 D), and steep K (−0.24 ± 0.29 D) between Lenstar LS900 and Myopia Master, with the Lenstar providing slightly longer axial length and steeper K values. Adults showed better repeatability with Myopia Master and better agreement between the biometers for axial length measurement than children. Neither axial length nor refractive error influenced the repeatability or agreement. CONCLUSIONS: Myopia Master is repeatable for the measurement of axial length and corneal curvature. Considering the differences in axial length between the Myopia Master and Lenstar LS900, caution must be applied when these biometers are used interchangeably.

[Thésaurus Mesh]Troubles de la réfraction oculaireMots-clés : optique ondulatoire réfraction objective Résumé : SIGNIFICANCE Increasing prevalence of refractive error requires assessment of ametropia as a screening tool in children. If cycloplegia is not an option, knowledge about the increase in uncertainty for wavefront-based autorefraction is needed. The cycloplegic agent as the principal variant presents cross-reference and allows for extraction of the influence of accommodation.
PURPOSE The purpose of this study was to determine the repeatability, agreement, and propensity to accommodate of cycloplegic (ARc) and noncycloplegic (ARnc) wavefront-based autorefraction (ZEISS i.Profiler plus; Carl Zeiss Vision, Aalen, Germany) in children aged 2 to 15 years.
METHODS In a clinical setting, three consecutive measurements were feasible for 145 eyes (OD) under both conditions. Data are described by spherical equivalent (M), horizontal or vertical astigmatic component (J0), and oblique astigmatic component (J45). In the case of M, the most positive value of the three measurements was chosen, whereas the mean was applied for astigmatic components.
RESULTS Regarding agreement, differences for ARc minus ARnc were statistically significant: for M, 0.55 (0.55 D; mean [SD]; P < .001), that is, more hyperopic in cycloplegia; for J0, −0.03 (0.11 D; P = .002); and for J45, −0.03 D (SD, 0.09 D; P < .001). Regarding repeatability, astigmatic components showed excellent repeatability: SD < 0.11 D (ARnc) and SD < 0.09 D (ARc). The repeatability of M was SD = 0.57 D with a 95% interval of 1.49 D (ARnc). Under cycloplegia, this decreased to SD = 0.17 D (ARc) with a 95% interval of 0.50 D. The mean propensity to accommodate was 0.44 D from repeated measurements; in cycloplegia, this was reduced to 0.19 D.
CONCLUSIONS Wavefront-based refraction measurement results are highly repeatable and precise for astigmatic components. Noncycloplegic measurements of M show a systematic bias of 0.55 D. Cycloplegia reduces the propensity to accommodate by a factor of 2.4; for noncycloplegic repeated measurements, accommodation is controlled to a total interval of 1.49 D (95%). Without cycloplegia, results improve drastically when measurements are repeated.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

[Thésaurus HELB]:Optique:correction de la vision
[Thésaurus HELB]:Optique:lunette correctriceRésumé : SIGNIFICANCE Our study suggests that patients would benefit from adjusting their distance spectacles several years after cataract surgery. This may lead to a better quality of life for these patients.
PURPOSE The purpose of this study was to determine whether patients' distance vision is optimally corrected with spectacles 6 to 7 years after cataract surgery and whether patients with glaucoma who regularly visit an ophthalmologist have more correct power in their spectacles.
METHODS A total of 153 patients (153 eyes) who underwent cataract surgery with phacoemulsification at Oslo University Hospital were examined 6 to 7 years after surgery. Patients with better or equal best-corrected distance visual acuity in the study eye compared with the other eye were included (n = 90; 59%). Vision-related outcomes were measured and analyzed, including a modified version of the visual function questionnaire, Visual Function-14 (VF-14).
RESULTS A significant difference was found in the logMAR score between the patients' habitual correction (if any) and those with best-corrected distance visual acuity measured at the postoperative study examination (0.20 ± 0.40 and 0.10 ± 0.39, respectively; P < .0001). Patients with glaucoma (n = 17) did not have more correct power of their spectacles than did patients without glaucoma (n = 73; P = .38). The overall mean VF-14 score was 89%, with a statistically significant correlation between a high VF-14 score and a good habitual distance correction (r = −0.82; P < .0001).
CONCLUSIONS This study indicates that, although the patients are quite satisfied with their visual function 6 to 7 years after cataract surgery, many patients are not making the most of their visual potential. Thus, there seems to be a need for better monitoring of patients' distance refraction and spectacle use for an extended period after cataract surgery.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
