Gullstrand's equationcan be used to calculate the effective focal length of a thick lens or two separated lenses with respect to the second principal plane. It is often useful to calculate the front and back vertex powersor focal lengths. For lenses with powers P1= diopters and P2= diopters. with separation d = cm,

If the ratio a'/a be sufficiently constant, as is often the case, the above relation reduces to the condition of Airy, i.e. tan w'/ tan w= a constant. This simple relation (see Camb. Phil.

It is often useful to calculate the front and back vertex powersor focal lengths. For lenses with powers P1= diopters and P2= diopters. with separation d = cm, there is a constant ratio (called the Gullstrand ratio from the Gullstrand exact schematic eye) between the anterior and posterior curvatures. For the post-LASIK cornea, how-ever, the Gullstrand ratio is reduced, and the keratometer-reported K reading will overestimate the true corneal power.
