“…Treatment options that have been proven to be effective by randomized clinical trials (RCTs) are low-dose atropine 8 and vision aids such as multifocal contact lenses 9 , orthokeratology lenses 10 , and spectacle lenses having included lens segments 11 , 12 . Myopia control management uses the therapeutic tools with the aim to decrease an eyeʼs excessive axial growth to approach at a growth rate that corresponds to the growth of children of the same age who become or stay emmetropic 3 , 4 , 13 . Thus, one essential element for proper myopia control management is the assessment of AL growth rate 14 through the measurement of AL (mm) at two points of time.…”

“…Biometer devices for the assessment of eye biometry have a longstanding use in the power calculation for intraocular lenses in mostly middle-aged or elderly patients who undergo cataract surgery or refractive lens exchange 1 , 2 . More recently, biometers have become important tools for ophthalmologists that focus on myopia control management in children and adolescents 3 , 4 . For myopia control management, it is important to detect any deviation from a normal growth pattern in a childʼs eye as early and as safely as possible and to start the appropriate treatment.…”

Purpose: To assess the reproducibility (i.e., inter-device reliability) of the biometers Topcon MYAH, Oculus MyopiaMaster and Haag-Streit Lenstar LS 900 with the Carl Zeiss IOLMaster 700 and the intrasubject repeatability in myopic children to reliably detect axial growth for myopia management. Methods: 22 myopic children (11.1 ± 2.4 yr) with a spherical equivalent of -3.53 ± 2.35 D were subject to each of the biometers to assess axial length (AL), corneal parameters (steepK, flatK, meanK, vectors J0, J45), of which 16 children agreed to a second round of measurements. Reproducibility of the first measurements between the IOLMaster and every other biometer was assessed employing a Bland-Altman approach and paired Student t-test. Repeatability was assessed as intra-subject standard deviation and was used to estimate the minimum time interval required between two axial length measurements to reliably detect axial growth of an eye of at least 0.1 mm/year. Results: Repeatability for AL measurements was IOLMaster: 0.05 mm, MyopiaMaster: 0.06 mm, Myah: 0.06 mm, Lenstar: 0.04 mm; the respective minimal time interval for axial growth assessment in myopia management was estimated as 5.6, 6.6, 6.7, and 5.0 months, respectively. Best reproducibility in AL measurement was found between IOLMaster and Lenstar (95% Limits of Agreement (LoA) for reproducibility -0.06 to 0.02). As for the means, Lenstar measures AL longer than IOLMaster by 0.02 mm (p<0.001). MyopiaMaster measures meanK significantly lower (by 0.21 D with p<0.001) than IOLMaster. Regarding J0, all biometers deviate significantly from IOLMaster measurements (p<0.05). Conclusion: A generally good agreement was observed between all the biometers. When assessing myopia progression in children a timeframe of at least six months between the AL measurements is advisable to reliably determine any deviation from a normal growth pattern.

“…To monitor the effectiveness of myopia treatment, we have developed a routine in which we compare a patient’s annual AL growth rate to the average physiological AL growth rate of an age-matched cohort of children who become and remain emmetropic. Epidemiological data from Truckenbrod et al 20 and our own data collection from emmetropic school children in Germany 30 were used to calculate the physiological AL growth rate. From the degree of agreement of the AL growth rate with the physiological axis growth rate, a conclusion can be drawn about the effectiveness of the current treatment.…”

Background/aimsDefocus incorporated multiple segments (DIMS) spectacle lenses are known to be able to inhibit axial length (AL) growth in myopic children compared with single vision (SV) spectacle lenses. However, it is not known whether AL growth is sufficiently inhibited to achieve the treatment goal of physiological AL growth.MethodsOf the data already collected in 2014–2017 by Lamet al, the AL growth with DIMS and SV spectacle lenses was re-evaluated according to the age-matched myopia control system. The individual AL growth after the first year of treatment of each eye was plotted against the corresponding age of the same time point in a colour-coded scheme. The two treatment groups were further subdivided based on their age and their baseline AL.ResultsOverall, 65% (61% of male, 70% of female) of eyes with DIMS spectacle lenses and 16% (16% of male, 16% of female) of eyes with SV spectacle lenses are within range of physiological AL growth rate. Median AL growth rate of eyes with DIMS spectacle lenses is also within the range of physiological growth. In the subgroups, eyes with DIMS spectacle lenses were also superior to the ones with SV spectacle lenses regarding this treatment goal. Of the children with SV spectacle lenses, older children and children with eyes with high baseline AL were least likely to achieve physiological AL growth rate.ConclusionsDIMS spectacle lenses can bring the AL growth rate of myopic children to the level of physiological AL growth rate, indicating 100% reduction of excessive myopic AL growth, independent of age and baseline AL. Older children and children with eyes with high AL have the risk to have increased AL growth without treatment.

ZusammenfassungEin übermäßiges Längenwachstum des Auges bei Kindern und Jugendlichen führt zu progredienter Myopie, die im Erwachsenenalter schwerwiegende Augenerkrankungen zur Folge haben kann. Es wurden bereits verschiedene Strategien zur Hemmung der Myopieprogression entwickelt. Das vorgestellte neuartige Einstärkenbrillenglas mit „Defocus Incorporated Multiple Segments (DIMS)“-Technologie erweitert das Portfolio der Myopietherapien um eine leicht anzuwendende nichtinvasive Option. Erste Studien dazu liefern vielversprechende Ergebnisse bei sehr geringem Nebenwirkungsprofil.
