| Summary: |
The wavefront sensing
device provides a new and objective way of mapping the
profile of refraction and of higher order defocus.
Higher-order optical errors of the human eye are often
responsible for reduced visual acuity, in spite of an
optimal spherical or cylindrical refraction. These
optical aberrations are of natural origin or can results
from operations on the eye, involving optical structures.
Nowadays, there are four different methods of wavefront
technology available: Concept of „Outgoing” Reflective
Aberrometry, Concept of „Retinal Imaging” Aberrometry,
Concept of „Ingoing” Adjustable Aberrometry (Spatially
Resolved Refractometer), Concept of „Double Pass”
Aberrometry. Wavefront analysis is a more sophisticated
method of defining aberrations that the surgeon is
trying to correct through refractive surgery. |
