编者按:香港理工大学的塑形镜研究一直走在前列,并且比较系统。从2006年发表的塑形镜配戴对眼轴控制有效的文章后,今年又发表高度近视者夜戴镜白天补戴框架眼镜,同样能控制眼轴的增加。该篇从散光换曲面塑形镜角度去研究对近视的眼轴控制,一样的有效。

Abstract
PURPOSE:
This nonrandomized clinical study aimed to investigatethe effectiveness of toric orthokeratology (ortho-k) for myopia control inmyopic children with moderate-to-high astigmatism METHODS: We enrolled 80subjects (aged 6-12 years; ortho-k, 43; control, 37) with myopia of 0.50 to5.00 diopters (D), and with-the-rule astigmatism of -1.25 to -3.50 D, andunremarkable ocular and general conditions. Data collection, including visualacuity, subjective and objective refraction, axial length, corneal topography,and biomicroscopy examination, was performed every 6 months during the 24-monthstudy period. Results from the right eye or the eye with higher astigmatismwere reported.
这项非随机的临床研究,旨在探讨环曲面塑形镜对有中度至高度散光的近视儿童的控制效果
方法:我们招收80人(6-12岁;角膜塑形镜组43人;对照组37人),0.50至5.00屈光度(D)近视,规则散光为-1.25~-3.50 D和无禁忌的眼部和一般条件。在24个月的研究期间,每6个月进行数据收集,包括视力,主观和客观验光,眼轴,角膜地形,裂隙灯检查。从右眼或具有较高的散光的眼睛的结果进行统计分析。
RESULTS:
A total of 35 ortho-k and 23 control subjectscompleted the study successfully. Subjects in both groups demonstrated axialelongation (P < 0.001). The average axial elongation at the end of study was0.31 ± 0.27 and 0.64 ± 0.31 mm in the ortho-k and control groups, respectively(P < 0.001). At the end of 24 months, axial elongation in ortho-k subjectswas 52% slower than that in the control group. Axial elongation was correlatedsignificantly with the initial age of the subjects (P = 0.02) and treatmentassigned (P = 0.04), but not with sex, initial myopia, initial refractivecylinder, or initial corneal toricity (P > 0.08).
共35名塑形镜配戴者和23名对照者成功地完成了这项研究。在这两个组均表现出的眼轴的增长(P <0.001)。在研究结束时,塑形镜组眼轴平均伸长率是0.31±0.27和对照组是0.64±0.31(P<0.001)。在结束的24个月,角膜塑形受试者的轴向伸长比对照组慢52%。眼轴增加与初始年龄的受试者(P = 0.02)和治疗分配(P = 0.04)显着相关性,但不与性别,初步近视度数和总散光、角膜散光角有关(P>0.08)。
CONCLUSIONS:
Toric ortho-k lenses can slow axial elongationeffectively in myopic children with moderate-to-high astigmatism.(ClinicalTrials.gov number, NCT00978692.).
环曲面的塑形镜能有效的减慢有中高度散光的近视儿童眼轴的增长。
