Wavefront technology in ophthalmology.
Wavefront sensing is an emerging technology that can measure irregular astigmatism as a higher-order wavefront aberration. The application of wavefront sensing in ophthalmology might enable the non-invasive observation of living retinal cone cells; the measurement of detailed visual function of the central nervous system by eliminating higher-order aberrations during examinations by adaptive optics; the correction of irregular astigmatism; and the prevention of iatrogenic irregular astigmatism induced by conventional refractive surgical procedures. In addition, it will be theoretically possible to obtain supernormal vision by wavefront-guided refractive surgery.
