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.

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].

First, according to the Gullstrand eye model, the AL of the eye globe is 24.38 mm [15], and other modified schematic eyes and investigation results have shown this length to be around 24 mm [16, 17]. these results, the authors calculated the new values of cardinal points for the eye, and compared with Gullstrand’s opti-cal schematic eye.

How Your Eye Works. Each eye has a lens -- a window made of clear While a change of 1 mm in a long eye will cause a change of only 0.6 D in refraction, a 1 mm shift will translate into 1.9 D of refraction in a short eye. Selection of a suitable IOL calculation formula is critical in these eyes. Dr. Haigis recommends the following formulae: Haigis, HofferQ and Holladay-2 with optimized IOL constants. • ADVANTAGES OF IOL MASTER 700 OVER LENSTAR- • In PSC cataracts, opacity are located nearer to the nodal point of the lens, so more light rays are affected and thus AL measurement becomes difficult with LENSTAR.

With this approach, a three-piece IOL of additional plus power of different material (e.g. silicone piggyback IOL in the presence of acrylic IOL in the capsular bag) can be used in a 1.5:1 ratio (IOL power:Refractive Error). Alternatively, an IOL exchange can be performed as well.

AcrySof IQ ReSTOR Multifocal Lens Implant. The AcrySof ® IQ ReSTOR ® IOL Intraocular lens made by Alcon Laboratories (Ft.Worth, TX) is an artificial lens that is implanted in the eye during cataract or refractive surgery to replace the eye's natural lens that has become cloudy or opaque. It is a unique technological innovation that can provide enhanced image quality and a full range of

The ZEISS IOLMaster sets a new standard for highly accurate, precise measurements of all ocular characteristics necessary for IOL power calculations. The Ze Introduction. Allvar Gullstrand (1862–1930) is the only ophthalmologist who has been awarded the Nobel Prize for work in ophthalmology. 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 Optical Biometer ADVANTAGES OF IOL MASTER 700 OVER LENSTAR- - In PSC cataracts, opacity are located nearer to the nodal point of the lens, so more light rays are affected and thus AL measurement becomes difficult with LENSTAR. IOL MASTER 700 overcomes this problem. - Unusual eye geometries like tilt or decentration of lens can be detected. 17.

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.
