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 aft er three instillations was statistically signifi cantly more compared to that found aft er one instillation. There was no statistically signifi cant diff erence in the mean hypermetropia between two and three instillations. There was no signifi cant eff ect of gender, age, and the presence and type of horizontal deviation. These observations suggest that two drops of cyclopentolate 1% 10 min apart are suffi cient for cycloplegic refraction in hypermetropes.
