17 amblyopic children between 4 and 9 years were fitted with high power plus extended wear soft contact lenses (Scanlens 24 h, Duragel 75) for optical occlusion of strabismic amblyopia. Amblyopia and eccentric fixation responded quickly to treatment between 2 to 13 weeks. Only one patient failed to reach 6/9, and 11 patients achieved equal visual acuity. Out of 10 patients with eccentric fixation only two remained eccentric after treatment. The contact lenses were tolerated by the children. Among the problems, concerning the use of extended wear soft contact lenses, should be mentioned fitting problems, deposits, loss of lenses (1 child needed 4 lenses) and occurrence of conjunctivitis (5 eyes). No major infections were seen. A one year follow-up showed that almost all the children needed renewed occlusion treatment. It is therefore recommended to continue with contact lens occlusion for at total period of 3 months.
17名4至9岁的弱视儿童佩戴高屈光度加长效软性隐形眼镜（Scanlens 24小时型、Duragel 75型），用于对斜视性弱视进行光学遮盖。弱视和旁中心注视在2至13周内对治疗反应迅速。只有1例患者视力未达到6/9，11例患者实现了视力相等。10例旁中心注视患者中，治疗后只有2例仍为旁中心注视。孩子们能耐受隐形眼镜。在与使用长效软性隐形眼镜相关的问题中，应提及配镜问题、沉积物、镜片丢失（1名儿童需要4副镜片）以及结膜炎的发生（5只眼）。未发现重大感染。一年的随访显示，几乎所有儿童都需要重新进行遮盖治疗。因此，建议继续使用隐形眼镜遮盖治疗，总疗程为3个月。
