Myopia prevalence is increasing worldwide. Axial length, refractive error, and keratometry are important outcome measures in myopia management. Precise measurement methods are required for myopia management. Various devices are used to measure these three parameters, and it is not known whether their results can be used interchangeably.
PURPOSE
The aim of this study was to compare three different devices to evaluate axial length, refractive error, and keratometry.
METHODS
A total of 120 subjects (37.7 ± 15.5 years) were enrolled in this prospective study. All subjects were measured with DNEye Scanner 2 (Rodenstock GmbH, Munich, Germany), Myopia Master (Oculus Optikgeräte GmbH, Wetzlar, Germany), and IOLMaster 700 (Carl Zeiss Meditec AG, Jena, Germany). Myopia Master and IOLMaster 700 use interferometry to measure axial length. Rodenstock Consulting software (Rodenstock GmbH, Munich, Germany) was used to calculate axial length from DNEye Scanner 2 measurement. Differences were analyzed using Bland-Altman 95% limits of agreement.
RESULTS
Differences for axial length were as follows: DNEye Scanner 2 versus Myopia Master, 0.67 ± 0.46 mm; DNEye Scanner 2 versus IOLMaster 700, 0.64 ± 0.46 mm; and Myopia Master versus IOLMaster 700, −0.02 ± 0.02 mm. Differences for mean corneal curvature were as follows: DNEye Scanner 2 versus Myopia Master, −0.20 ± 0.36 mm; DNEye Scanner 2 versus IOLMaster 700, −0.40 ± 0.35 mm; and Myopia Master versus IOLMaster 700, −0.20 ± 0.13 mm. The difference in noncycloplegic spherical equivalent between DNEye Scanner 2 and Myopia Master was 0.05 ± 0.25 D.
CONCLUSIONS
The results for axial length and keratometry from Myopia Master and IOLMaster were comparable. The axial length calculated by DNEye Scanner 2 was significantly different from interferometry devices and is not appropriate for myopia management. The differences in keratometry readings were clinically not significant. All refractive outcomes were comparable.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

During computer work in controlled laboratory conditions, wearing multifocal contact lenses (MFCLs) showed no lower muscle load but increased subjective perception of comfort with equivalent visual quality and comparable tolerance.
PURPOSE
Because musculoskeletal complaints are frequent among computer workers, this study used the muscle electrophysiological activity of shoulder and neck muscles in presbyopic computer workers who received either progressive addition lenses for general purpose (GP-PALs) or MFCLs.
METHODS
For this crossover study, 11 presbyopic computer workers aged 55 ± 4 years (mean ± standard deviation) were equipped with GP-PALs and MFCLs in a randomized order. Surface electromyography signals were recorded bilaterally from shoulder and neck muscles during short-term computer work tasks using an optimally adjusted visual display unit workplace. The amplitude probability distribution function, the number and total duration of EMG gaps, and sustained low-level muscle activity periods of the surface electromyography signals were calculated. Comfort and correction type preferences were assessed. Head inclination was objectively evaluated.
RESULTS
Multifocal contact lenses elicited no significant lower muscle load than GP-PALs. The number of sustained low-level muscle activity periods longer than 60 seconds was similar between visual aids. The total amount of gaps was significantly higher with MFCLs (44 gaps) compared with progressive addition lenses for general purpose (15 gaps) in all analyzed periods for all participants. However, there were no significant differences for the median in the intraindividual comparisons (P = .22, dz = 0.52). Multifocal contact lenses scored statistically significant higher in comfort values with equivalent visual quality and comparable tolerance (P = .003, dz = 1.51).
CONCLUSIONS
Although the study failed to show clear results, wearing MFCLs seems to enhance working comfort compared with GP-PALs subjectively.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
