Figure 9-1 Schematic representation of the Helmholtz theory of accommodation, in which contraction of the ciliary muscle during accommodation (bottom) leads to relaxation of the zonular fibers. The reduced zonular…
Because accurate testing results are crucial to the success of refractive surgery, the refractive surgeon must closely supervise office staff members who are performing the various tests (eg, corneal topography…
