Comparative characteristics of the results of objective and subjective methods of studying astigmatism before and after cycloplegia

The work aimed to assess the results of the study of astigmatism by subjective and objective methods before and after cycloplegia in military personnel and to clarify the degree of accuracy in determining and correcting astigmatism. We used the subjective method of studying the Krichagin-Volkov refraction and the objective one - skiascopy and refractometry simultaneously in 76 people (152 eyes). The results of the study showed high accuracy of refractive indices with subsequent spectacle correction of astigmatism using the Krichagin-Volkov method in conjunction with skiascopy. The study of astigmatism by three methods at a young age without the use of cycloplegia is unacceptable. In the absence of an autorefractometer in the ophthalmological office, the selection of cylindrical and spherocylindrical corrective glasses using the Krichagin-Volkov method is irreplaceable.
