On performing refraction using a plane mirror on a patient who has a refractive error of -3 D sphere with -2 D cylinder at 900 from a distance of 1 metre under no cycloplegia, the reflex would be seen to move
C i.e. Against the movement in both the axis The patient in question is having astigmatism because he has different refractive power in two axis (-3 D in horizontal & -2D in veical axis). Thus in both the axis, myopia is of > 1D.
