Gullstrand. Gullstrand är ett svenskt släktnamn vars äldste kände stamfader är Nils Olofsson, född i slutet av 1600-talet. Han var trädgårdsmästare först vid egendomen Ek i Eks socken i Västergötland, sedan från 1724 vid Sjöberg i Björsäters socken i samma landskap. Han efterträddes i tjänsten av sonen Olof Nilsson.

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. Gullstrand lab UNIVERSITET The optics of the eye is an antenna Detection of electromagnetic radiation (400-760 nm) emitted from the sun and scattered on objects on the surface of the earth ng2 Collection of scatterred radiation Optical system Matrix of photodetectors Retina Optical mount The eye wall + sligthly higher pressure The Swedish ophthalmologist and self-taught mathematician Allvar Gullstrand (1862-1930) invented the slit lamp to illuminate the anterior of the eye. With its rectangular beam of very bright light, he studied the structure of the cornea and the function of the lens. GELP - Gullstrand-Emsley Lens Power. Looking for abbreviations of GELP?

He gave mathematical descriptions of the dioptric system of the human eye with Scarce offprint issue of Gullstrand's doctoral thesis on the astigmatism, in the field of ophthalmological optics, the study of the human eye as an optical system.

The first of these was Gullstrand's No. 1 ‘exact’ eye 10 in 1909, which had two corneal and four lens surfaces. It has both relaxed and accommodated (10.9 D) forms (Figure 6 D). The outer cortex had a refractive index of 1.386 and the inner nucleus had a refractive index of 1.406.

Gullstrand's research offered detailed With the high-precision 3D eye measurement of the DNEye ® Scanner from Now, Rodenstock has broken new ground to replace the "Gullstrand's Eye". 11 Nov 2013 1.1 Optical Properties. In the Exact Gullstrand Eye, we assume the refracting surfaces to be spherical and centered at a common optical axis. Theoretical P IOL overestimation up to −5.6 D and −6.2 D using Le Grand and Gullstrand eye models was found for a keratometric index of 1.3375.

Since 1900, a general model of the human eye has been used for the measurement of the eye and the calculation of lenses. Over time, technology and lenses have continously improved. But the so-called "Gullstrand Eye" as the standard calculation basis remained the same. Now, Rodenstock has broken new ground to replace the "Gullstrand's Eye".

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.
