In a postsurgical cornea, standard keratometry or simulated keratometric values from topography cannot accurately measure the corneal curvature, and the calculation of corneal refractive power by ...
Refracts light to focus it onto the retina. The amount of refraction can be adjusted by altering the thickness and curvature of the lens. Ciliary muscles Muscles connected to the lens by ...
In corneal refractive surgery ... including technology for accurately measuring posterior corneal curvature and improved displays, particularly for evaluating corneal wavefront aberrations.
