儿童混合散光配镜原则(学习笔记及时整理)
  先举例：4岁儿童，右眼R：+1.50-3.25X170   矫正视力VA 0.6
                              左眼L：+1.50-3.75X5     矫正视力VA 0.6 
思考：需要减+1.00D 的生理远视吗？
解析：
  混合散光的处方给予关键在于最小弥散圆和视网膜的位置关系，即等效球镜。
1等效球镜为负，例如+1.00-3.00X180
处理：散光度数全部矫正，不能降低任何正镜度数。
2等效球镜为零，例如+1.50-3.00X180
处理:散光度数全部矫正，不能降低任何正镜度。
3等效球镜为正  例如+4.50-5.00X175
处理：散光全部矫正，可以降低正镜度，一般情况下可降低+1.00DS，但是需要注意不能超过等效球镜的数值。
现在再看一下4岁儿童的最终配镜度数就容易判断多了。
附加这位4岁儿童可能出现的现象
可能他当时的裸眼视力就能达到0.5，戴上眼镜视力能达到0.6，这么来看家长会认为，这戴上眼镜才提升1行，也没提升多少，心里可能犯嘀咕。这个时候要和家长说，一开始可能是这样，让小孩坚持佩戴，我们三个月后再复查看一下。
 3个月后复查视力恢复0.8-
半年后复查视力恢复0.9-
1年后视力恢复1.0
所以不要着急，等待恢复。
