Abstract:
Background: A blurred image caused by the shape of the eye which does not bend light correctly. It is a major health problem globally affecting a large number of people with many ocular morbidities. Aim: The aim of the study was to compare the noncycloplegic refractive error with cycloplegic refractive error using autorefractometer. Materials and methods: This study was conducted in Department of ophthalmology, Nizam Medical College, Hyderabad between August 2018 to August 2019. Total number of patients selected were 70. Results: Autorefractometer values were comparable between pre and post cycloplegic values which were 23 and 24 right and left eyes of hypermetropia patients. From dioptric range, number of patients increased significantly (+0.25 to +1.25) to (+2.75 to +3.75) which was 11 to 26 and 21 to 32 right and left eyes respectively. P value in right eye and left eye was <0.0000001, which was significant. Autorefractometer values were comparable between pre and post cycloplegic values which were 38 and 36 right and left eyes of myopic patients. Number of patients decreased in dioptric range (-2.75 to -3.75) from 23 to 2 in right eyes. Number of patients decreased in dioptric range (-4.00 to -5.00) from 17 to 0 in left eyes. In myopic astigmatism, there was no significant shift in number of patients pre and post dilation in both eyes. Conclusion: Measurement of refractive error is influenced by accommodation in younger patients. Hypermetropia is underestimated and myopia is overestimated without cycloplegic refraction using autorefractometer. Post cycloplegic autorefractometer values were accepted by all patients and without any complications with good visual acuity.
