目的通过对Suresight手持式自动验光仪在学龄前儿童中筛查屈光不正可行性的探讨,为其在婴幼儿屈光不正筛查中的应用提供理论支持,寻求一种能简单、方便、可靠、客观反映婴幼儿屈光发育情况的筛查方法。方法对就诊的4～6岁的学龄前儿童共148人次,296眼在自然状态下使用Suresight手持式自动验光仪进行屈光检查,与连用1%阿托品2次/日,5天后检影验光的结果比较。结果Suresight手持式自动验光仪屈光检查的结果中柱镜及其轴向与散瞳验光结果的差异无统计学意义(柱镜t=0.902,P=0.368;柱镜轴向t=0.935,P=0.350),球镜及等效球镜的差异有统计学意义(球镜t=2.231,P=0.026;等效球镜t=10.731,P=0.000),Suresight手持式自动验光仪屈光检查的结果球镜及等效球镜比散瞳验光结果轻度偏正,球镜平均0.1759±1.3444D,等效球镜平均0.8679+1.3796D。本文4～6岁的学龄前儿童296眼中远视性屈光不正占多数,比例为64.2%。结论Suresight手持式自动验光仪是一种用于学龄前儿童比较可靠的屈光不正的筛查工具。提示它在婴幼儿屈光不正的筛查中有一定的临床意义。
Objective To explore the feasibility of using Suresight hand-held autorefractometer to screen refractive errors in preschool children, and to provide theoretical support for its application in refractive error screening of infants and young children, and to seek a simple, convenient and reliable , Objectively reflect the infant refractive development of the screening method. METHODS: A total of 148 preschoolers aged 4 to 6 years were enrolled in this study. 296 eyes were examined under natural conditions using a Suresight handheld autorefractor and twice daily with 1% atropine. Results comparison. Results There was no significant difference between the cylinder and the axial and mydriatic optometry results in the Suresight handheld autorefractometer (t = 0.902, P = 0.368; t = 0.935, P = 0.350). There were significant differences between spherical and spherical equivalent (spherical t = 2.231, P = 0.026; equivalent spherical t = 10.731, P = 0.000) The results of spherical and equivalent spherical than the Mydriasis optometry results were mildly positive, spherical average 0.1759 ± 1.3444D, equivalent spherical average of 0.8679 + 1.3796D. In this paper, 4 to 6-year-old presbyopic 296 patients with presbyopia refractive majority, accounting for 64.2%. Conclusion The Suresight Handheld Auto Refractometer is a reliable screening tool for preschool children with refractive errors. Suggesting that it has some clinical significance in infants refractive examination.
