Gullstrand studied in Uppsala, Vienna, and Stockholm, earning a doctorate in 1890. He became professor of diseases of the eye at the eye structural parameters, being acknowledged the fact that the most influenced is the eye lens [1-3]. Most early eye models such as Emsley’s reduced eye, Gullstrand simplified or Gullstrand-le Grand eye, Swiegerling eye can be described as ideal theoretical models due to their assumptions valid in the paraxial domain [5], [8-9], [11-12]. Results: Among 124 eyes, 12, 3, and 5 eyes failed to be measured of AL by IOL Master 500, IOL Master 700 and Lenstar LS900, respectively.

In total, 80 eyes were measured using IOL-Master and Lenstar, and these results were compared. Repeatability of Ophtha Top Topography Table 1 shows the repeatability of flat K, steep K, Km, and astigmatism vectors J0 and J45 measured by Ophtha Top topography.

Der ZEISS IOLMaster 500 ist eine gute Wahl für Kataraktchirurgen, die ein zuverlässiges, schnelles und einfach zu bedienendes optisches Biometriegerät für präzise Messungen suchen. 2019-04-08 · I have a patient with silicone oil in the eye and cataract. The retina surgeon says that he never wants to remove the oil. The macula looks ok. The patient’s fellow eye is -2.00 and he requests that his surgical eye (OD) be -2.00. IOL Master 700 set on silicone oil mode recommends a 19.5 diopter DCBOO implant for -1.85 postop refraction. Gullstrand, "The optical system of the eye," Physiological Optics, vol.

2014-09-16 In IOL formulas, the lens itself is represented by specific constants. The effect of axial length on different IOL constants was studied on model calculations in theoretical ametropic eyes derived from the standard Gullstrand eye as well as in clinical results obtained for different surgical centers within the ULIB project in optical biometry. The Gullstrand-Emsley schematic eye shows refractive shifts of 8.710, 4.544, 1.136, and 0.338 D in PPV eyes; 11.044, 20.332, 16.351, and 17.413 D in PPV plus lensectomized eyes; and the need for IOL powers of 22.195, 22.366, 22.292, and 22.312 D in PPV plus IOL eyes in silicone oil, heavy silicone oil, hydrogels, and encapsuled bal- 2018-04-12 Laureate, Sweden) (Gullstrand 1909) and Marius Tscherning (Denmark) (Norn & Jensen 2004).

• 1952 - Emsley made a single surface model for simplicity and speed of raytracing. Today, computers can quickly raytrace eye models, so The refractive effect of the IOL depends on the optic configuration (shape factor) of the IOL, its position within the eye, the power of the implant and the amount of spherical aberration. The optic configuration of the IOL determines the effective lens plane, which represents the principal plane when dealing with paraxial ray tracing. 2017-01-10 · Dr. Harold Ridley (1906-2001), who implanted the first intraocular lens in 1949, lived to see cataract surgery evolve into a true refractive procedure, undergoing IOL implantations himself in 1989 and 1990.

For the main purpose of this study, a formula based on the Gullstrand simplified schematic eye was applied to the calculation of individual AL and was tested for applicability. For the first derivation of the equation, a corneal radius of 7.8 mm and an AL of 24.0 mm were used in the original Gullstrand simplified schematic eye [ 19 ], and a
