[The effect of keratoconus-associated refractive errors on the results of tomographic methods of studying the posterior structures of the eye].

The results obtained in this study demonstrate the practicality of tomographic examination in KC with contact correction. The optimal choice is custom-fit SHCL, which along with proper correction of refractive errors also ensures stable position of the lens on the cornea. In standard examination specialists should take into account the «false» decrease in parameters of the peripapillary retinal nerve fiber layer and increase in ONH cupping.
