Visually, spherical aberration causes blur, loss of contrast and halos around lights. Surgery such as LASIK can worsen HOAs in the eye — particularly, spherical aberrations. Procedures like keratoplasty (corneal transplants) can also increase the risk of developing spherical aberration. Spherical aberration can … See more An aberration (which literally means a deviation from the usual or natural) of the eye occurs when there is an abnormality on the surface of the cornea. As mentioned, some degree of aberration is natural in every eye, … See more Higher-order aberrations such as spherical aberration are so complex that they cannot be improved with ordinary eyeglasses or soft contact lenses. However, they can be treated with rigid contact lenses. Some … See more Aberrations can be examined and diagnosed through wavefront technology(aberrometry), using an instrument called an aberrometer. Aberrometry … See more It is normal to have some degree of aberration — as no eye is perfect — but if it is unusually high, vision can be noticeably affected. In particular, … See more WebSep 29, 2024 · We propose to construct the higher-order tensor in the frequency domain by spherical harmonics transform. The designed symmetry quantification in Sect. 2 is employed to mimic the diffusion signal required in HARDI. The higher-order tensor construction in the spherical frequency domain will be remarkably more efficient than that …
