配戴高非球微透鏡鏡片之兒童近視進展評估

目的評估配戴高非球微透鏡鏡片(Highly Aspherical Lenslets Lenses)的近視兒童在一年內的近視進展以及周邊屈光變化。方法本研究於中山醫學大學視光學系實驗室進行，納入32位8～15歲學童，等效球面屈光度為-1.00 D～-6.00 D之間，分組為低年級組(n=15)以及高年級組(n=17)，配戴研究用鏡片後，分別在基線、4、8、12個月測量等效球面屈光度(SER)、眼軸長(AL)、周邊屈光(RPR)以及視覺功能檢查，並且在所有回訪期間以及每兩個月電話訪談中都進行視覺功能不適以及日常生活舒適度問卷評估。結果一年的研究結果，對於低年級組以及高年級組，SER平均變化分別為，-0.10D ± 0.21 D(P=0.18)、-0.11 ± 0.35 D(P=0.26)，眼軸長的變化分別為0.09 ±0.19 mm(P=0.31)、0.13 ± 0.22 mm(P=0.26)；RPR於高年級組中20N、20T有顯著變化，分別為-0.37 ± 1.27 D (P=0.04)、-0.19 ± 1.28 D(P=0.02)，呈現近視位移，J0以及J45變化在回訪期間均無顯著差異。結論本研究結果證實了在不同的年齡層都有顯著的效果。於高年級組RPR周邊20N、20T有顯著變化，呈現近視位移，這有可能是因為高年級組學童依從性較高，在低年級組當中則無出現顯著差異。高非球微透鏡鏡片為臨床兒童近視管理提出了一個舒適性高且適應性好的選擇。

PurposeTo evaluate the effect of highly aspherical lenslets(HAL) lenses on myopia control in Taiwan myopic children.MethodThirty-two Taiwan school children aged 8-15 years with myopia of -1.00 D to -6.00 D were received spectacle lenses with highly aspherical lenslet. All subjects were divided into two groups: lower grade (LG) group (n=15) and higher grade (HG) group (n=17). Spherical equivalent refraction (SER), axial length (AL), relative peripheral refraction (RPR) and visual functional were measured at baseline, 4, 8, and 12-month. Adaptation and compliance questionnaires were evaluated during all visits. Furthermore, visual function and life style questionnaires also administered by telephone interview every two month.ResultsAfter one year, the mean SER change in the LG and HG group represented -0.10D ± 0.21 D(p=0.18) and -0.11 ± 0.35 D (p=0.26), respectively. The mean AL change were 0.09 ± 0.19 mm(p=0.31) in LG group and 0.13 ± 0.22 mm(p=0.26) in HG group. In HG group, the RPR showed significant myopic shift at 20N and 20T (-0.37 ± 1.27 D(p=0.04) and -0.19 ± 1.28 D(p=0.02).ConclusionIn this study, the HAL lens significantly slow myopia progression and axial elongation in both group. The HAL lens might be a new strategy for myopia control.
