Correlation of the Jackson cross cylinder test and the Matsuura autocross test as to cylinder axis and power, subject preference, and administration time

1 April 1968


The purpose of this study is to compare the efficiency of the Matsuura AutoCross with that of the Jackson Cross Cylinder (JCC) in revealing the existance of astigmatism, its axis and amount in the human eye, and to determine if the AutoCross technique was a valid one and could be a practical substitution for the Jackson Cross Cylinder test.
