23 Mar 2021 Until recently, paraxial biometric formulas were based on a thin lens eye model, where the corneal Gullstrand equation in a thick eye model.

The complete solution of this problem became the first task of Gullstrand in his work towards his ultimate goal. He has completed his task. He has transformed the theory of optical image-formation and has formulated the fundamental equation from which are derived the hitherto unknown laws of optical image-formation.

next section. Equation (7) represents the general line element for static and spherically symmetric spacetimes. Now, we can use (7) to actually solve the ﬁeld equations. Using GRTensor, we ﬁnd that Gt t = − h′r +h(h−1) r2h2, Gr r = − −f′r +f(h−1) hfr2, (8) where a prime indicates d/dr. By setting these equal to zero, we have a The Human Eye as an Optical System Milton Katz Philip B. Kruger Introduction The eye is a compound optical system composed of a cornea and a lens shown in Figure 1.

From surfaces 1 to 2, a power matrix of the lens may be called the Gullstrand equation, generalized in that it follows from rays traced through toric surfaces with matrix powers and . A lens is stationary and as surface powers in expressions are interchanged, this transposition represents light first incident on a “back” refracting surface.

These equations of motion are simpler than the usual geodesic equations obtained from Christoffel tensors, in that the affine parameter is eliminated. The various terms can be compared against tests of gravity.
