Aim and objectives: The present study was undertaken to compare subjective and objective (autorefractometer and retinoscopy) methods of refraction, before and after using cycloplegics. Material and Methods: The present prospective study, comprised 200 eyes of 100 patients with visual acuity <6/12 and patients having asthenopic symptoms. The results of subjective refraction testing were compared with the readings from auto refractometer and retinoscopy with and without the use of cycloplegia. Statistically data was compared using chi-square test and p value ≤0.005 was considered significant. Results: The present study found that in hypermetropic patients mean and standard deviations of spherical error and spherical equivalence were very different when calculated before using cycloplegic as compared to post cycloplegic values, where as cycloplegia had no significant effect on values of cylindrical error. They were same with all the three methods both before and after using cycloplegic. In myopic patients there was no significant difference of mean and standard deviations values between all the three parameters by using autorefractometer, retinoscopy and subjective method both before and after using cycloplegic. Conclusion: Non-cycloplegicre fraction cannot be considered as a reliable method to assess the refractive error in children.
