Matrix formula for intraocular lens power calculation.
The matrix calculation was applied to Gaussian optics. Matrices were defined for a single diopter, a lens, an association of two centered systems having the same axis when the origins are taken at the vertices of the first and last refracting surfaces. The matrix formula then was used to calculate the power of the emmetropizing lens implant, and its results compared with the ones obtained by fi...
متن کاملAccuracy of Intraocular Lens Power Calculation Formulas for Highly Myopic Eyes.
Purpose. To evaluate and compare the accuracy of different intraocular lens (IOL) power calculation formulas for eyes with an axial length (AL) greater than 26.00 mm. Methods. This study reviewed 407 eyes of 219 patients with AL longer than 26.0 mm. The refractive prediction errors of IOL power calculation formulas (SRK/T, Haigis, Holladay, Hoffer Q, and Barrett Universal II) using User Group f...
متن کاملcomparison of refractive outcomes of different intraocular lens power calculation formulas in keratoconic patients undergoing phacoemulsification
purpose: in the present study we have tried to find the most reliable intraocular lens (iol) power calculation formula in patients with keratoconus (kcn) and cataract. methods: in a prospective case series between october 2010 and march 2012, eligible patients with cataract and kcn underwent phacoemulsification with iol implantation. preoperatively, based on iol master keratometric data iol pow...
متن کاملAccuracy of Intraocular Lens Power Calculation Formulas in Primary Angle Closure Glaucoma
PURPOSE To compare the accuracy of intraocular lens (IOL) power calculation formulas in eyes with primary angle closure glaucoma (ACG). METHODS This retrospective study compared the refractive outcomes of 63 eyes with primary ACG with the results of 93 eyes with normal open angles undergoing uneventful cataract surgery. Anterior segment biometry including anterior chamber depth, axial length,...
متن کاملAccuracy of Various Intraocular Lens Power Calculation Formulas in Steep Corneas
PURPOSE To compare the accuracy of four different intraocular lens (IOL) power calculation formulas for eyes with mean keratometry values greater than 46 diopters (D). METHODS Forty five eyes from 45 patients who were candidates for senile cataract surgery with mean keratometry values greater than 46 D were included. Calculation of the IOL power was performed by the Lenstar. The implanted IOL...
