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.
