9), designed by Allvar Gull- strand and produced by the Carl Zeiss company from about 1911. Gullstrand schematic eye: The exact schematic eye was based on his very precise measurements on the human eye. 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. Again, the formula will think the IOL power should Gullstrand was an honorary Doctor of Philosophy of the Universities of Uppsala, Jena and Dublin, and a member of a number of Swedish and foreign scientific societies. In 1911 he received the Nobel Prize for his work on the dioptrics of the eye. To make simple optical calculations a Reduced Schematic Eye, based on Gullstrand’s model, was later developed that approximately matches the ocular dimensions but simplifies the calculations by combining all the refracting surfaces into one power and location and all the refractive indices into one.

The results are in agreement with experimental values. Gullstrand eye model divides the refractive power of the eye into three main components: anterior cornea (point A), posterior cornea (point B), and lens (point C). TABLE 1. Variables Used in the Gullstrand Eye Model Variable Description Average Value/Figure Standard Gullstrand Eye Model Variable F eye Power of the eye 58.6 D Yes F The Total Keratometry (TK ®) of ZEISS IOLMaster 700 allows you to directly measure the posterior corneal surface using SWEPT Source OCT. In a study the exclusive Barrett True K with TK formula improved the outcome prediction compared to the Barrett True K with Classic Ks within ±0.5 D by >12 % (p = 0.04) in post-myopic LASIK eyes 1. Born at Landskrona, Sweden, Gullstrand was professor (1894–1927) successively of eye therapy and of optics at the University of Uppsala. He applied the methods of physical mathematics to the study of optical images and of the refraction of light in the eye. For this work, he received the Nobel Prize in Physiology or Medicine in 1911.

Now, Rodenstock has broken new ground to replace the "Gullstrand's Eye". Abstract. Allvar Gullstrand (1862–1930) was a Swedish ophthalmologist whose study of the physiological and geometric optics of the eye challenged existing theories by discovering new ways of examining the structures of the eye.

Abbe’s refractometer, by temperature of 33 °C for aqueous, and 36 °C for vitreous, as it’s in human eye. In the principle of these results, the authors calculated the new values of cardinal points for the eye, and compared with Gullstrand’s opti-cal schematic eye.

Today, computers can quickly raytrace eye models, so The Gullstrand schematic eye with a power of 58.64 D and an axial length of 24.4 mm represents a typical emmetropic eye.
