WebSpherical aberration (SA) was defined as the RMS of Z 4 0 (spherical aberration) and Z 6 0 (secondary spherical aberration). Coma aberration was defined as the RMS of Z 3 –1 and Z 3 1. S A = Z 4 0 2 + Z 6 0 2 C o m a = Z 3-1 2 + Z 3 1 2. Classification of corneal shapes into five topographic patterns. Topographic patterns were categorised ... WebApr 12, 2024 · Intinya.

WebThe sum of all these circles results in a V-shaped or comet-like flare. As with spherical aberration, coma can be minimised (and in some cases eliminated) by choosing the curvature of the two lens surfaces to match the application. Lenses in which both spherical aberration and coma are minimised are called bestform lenses. Chromatic aberration
