Today, computers can quickly raytrace eye models, so In the principle of these results, the authors calculated the new values of cardinal points for the eye, and compared with Gullstrand's optical schematic eye. So, the refractive power for the eye F = 59.98 D, first focal length f1 = -16.67 mm and second focal length f2 = +22.27 mm. From left to right they are the distribution of Gullstrand from which his shell lens model was developed, 10 the lens of the Liou and Brennan schematic eye 35 and a distribution pattern according to Navarro, Palos and Gonzáles. 31 For the latter, the point of highest refractive index has moved toward the back of the lens, as has been found experimentally 36 but the lens shape is not anatomically accurate at the equator. Gullstrand's NO.1 (exact) schematic eye 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.

Dioptrik d. Auges d. Menschen«. For this work Gullstrand received a Nobel Prize in 1911.1. As yet today, the Gullstrand’s schematic eye exist, sometimes with modification because the dif-ferent values of optical and anatomical of the eye(index of refraction of optical eye media, radius curvature of cornea and lens, axial length of eye globe). Our study and First, according to the Gullstrand eye model, the AL of the eye globe is 24.38 mm, and other modified schematic eyes and investigation results have shown this length to be around 24 mm [16, 17].

The other ophthalmologists who received Nobel Prize Awards were Fritz Pregl in 1923 ‘for his invention of the method of micro‐analysis of organic substances’ and Walter Hess in 1949 ‘for his discovery of the functional organization of the interbrain 2018-05-01 · An accommodated variable version of Gullstrand's exact eye model was defined later by Atchison and Smith. 28 Gullstrand introduced the exact eye model in 2 forms; that is, nonaccommodated and accommodated to 10.87 D. Atchison and Smith modified this eye so its parameters are defined as a function of the accommodated state by assuming that the ACD, lens thickness, and anterior and posterior curvatures of the lens cortex and lens core surfaces vary with accommodation. The reduced eye is an idealized model of the optics of the human eye.

Gullstrand studied in Uppsala, Vienna, and Stockholm, earning a doctorate in 1890. Introduction.
