Intraocular lens calculation for aspheric intraocular lenses.
PURPOSE To evaluate the possible benefits of biometry and ray-tracing intraocular lens (IOL) calculation for aspheric aberration-correcting IOLs. SETTING Private eye clinic in Germany. DESIGN Retrospective consecutive case series. METHODS Eyes with 3 different aberration-correcting IOLs were reviewed. Before surgery, the axial length, corneal thickness, anterior chamber depth, crystalline...
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 کاملIntraocular Lens Power Calculation Using IOLMaster and Various Formulas in Short Eyes
PURPOSE To evaluate the predictability of intraocular lens (IOL) power calculations using the IOLMaster and four different IOL power calculation formulas (Haigis, Hoffer Q, SRK II, and SRK/T) for cataract surgery in eyes with a short axial length (AL). METHODS The present study was a retrospective comparative analysis which included 25 eyes with an AL shorter than 22.0 mm that underwent uneve...
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...
