To find the optimal dosage of cyclopentolate 1% for cycloplegic refraction in hypermetropes with brown irides, we investigated the difference in cycloplegic auto-refractions obtained after one, two, and three instillations in the same patient. The mean hypermetropia found after three instillations was statistically significantly more compared to that found after one instillation. There was no statistically significant difference in the mean hypermetropia between two and three instillations. There was no significant effect of gender, age, and the presence and type of horizontal deviation. These observations suggest that two drops of cyclopentolate 1% 10 min apart are sufficient for cycloplegic refraction in hypermetropes.
为了找到棕色虹膜远视患者中用 1%环戊通散瞳验光的最佳剂量，我们在同一位患者身上比较了单次、两次和三次滴眼后获得的散瞳自动验光结果的差异。三次滴眼后的平均远视度数明显高于一次滴眼后的平均远视度数。两次和三次滴眼后的平均远视度数之间没有统计学上的显著差异。性别、年龄以及水平斜视的存在和类型对平均远视度数没有显著影响。这些观察结果表明，每隔 10 分钟滴两次 1%环戊通滴眼液足以用于远视患者的散瞳验光。
