[Automatic refractometry, reliability of the determination of type and degree of refraction anomalies]

The authors report on their experience with and results of using the AR-1000 autorefractometer made by Nidek, particularly with the pre-school children, school children, and students up to 24 years of age. They stress the significance, as well as speed and accuracy of automatic refractometry findings in large groups of testees (regular checkups) as a valuable indicator in one of numerous necessary tests with the aim to determine and correct visual acuity. There is a significant error reduction in the estimate of dioptries when autorefractometry is done in cycloplegia as compared to autorefractometry without cycloplegia.
