Allvar Gullstrand, Swedish ophthalmologist, recipient of the 1911 Nobel Prize for Physiology or Medicine for his research on the eye as a light-refracting apparatus. Gullstrand studied in Uppsala, Vienna, and Stockholm, earning a doctorate in 1890. He became professor of diseases of the eye at

He was educated at schools in Landskrona and Jönköping, where he passed his matriculation in 1880; he then went to Uppsala University, which he left in 1885, and spent a year at The invention furthermore relates to a system and a method for predicting the optical outcome of IOL surgery. Use of the system may provide prevention, treatment, or amelioration of diseases and disorders affecting the lens of the eye and which may benefit from IOL surgery. 25.14 ± 1.87 mm by IOL Master in normal eyes group and 24.91 ± 1.80 mm by A-scan ultrasound and 24.03 ± 2.00 mm by IOL Master in detached eyes group, respectively. The mean axial length by A-scan ultrasound was shorter 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 95% LOAs of the Javal keratometer with TMS4-topography, Pentacam, and IOL Master were - 0.361 to 0.49, -0.01 to 1.14, and - 0.36 to 0.36 D, respectively. Conclusion: Although the correlation of Pentacam, TMS4-topography, IOL Master, and Javal keratometer in measuring keratometry was high, only the IOL Master showed no significant difference Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye.Since the cornea is normally responsible for some 70% of the eye's refractive power, its topography is of critical importance in determining the quality of vision and corneal health.

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. The AL measured by Lenstar LS900 was longer than that measured by IOL Master 500 and IOL Master 700 (p < 0.001, p = 0.002, respectively). 2019-04-08 House-12/A, Road-05, Mirpur Main Road, Dhanmondi, Dhaka-1215, Bangladesh.

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

IOL Master. This is one of the most sophisticated and accurate ways to determine the power of the intraocular lens (IOL) implant for cataract surgery. The IOL Master allows for fast, accurate measurements of multiple areas of the eye, such as eye length and surface curvature, which are necessary for cataract surgery. NOTE 3 Any IO-Link Master or Device shall provide an associated manufacturer declaration on the conformity of the device with the "IO-Link Interface and System" … To investigate the influence of the AP ratio on IOL power calculation error, subgroup analyses were performed on 181 patients (181 eyes) who met the following conditions: 1) They underwent only cataract surgery; 2) their axial length was measurable with IOL Master™ before cataract surgery; 3) cataract surgery was performed using a 3.0-mm temporal clear corneal incision; 4) IOL implantation 1999-05-01 Any IOL power calculation has three key ingredients, according to Uday Devgan, MD: (1) the power of the cornea, (2) the axial length of the eye, and (3) the effective lens position (ELP).

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

The model has a total axial length of 22.22 mm, a corneal radius of 5.55 mm, and an For hyperopic surprise, a secondary piggyback IOL may be considered. 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.

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.
