Accuracy 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 کاملIntraocular lens power calculation and optimized constants for highly myopic eyes.
PURPOSE To determine the accuracy of intraocular lens (IOL) power calculations in eyes with high myopia and to suggest adjusted constants for these cases. SETTING Centre for Ophthalmology, Eberhard-Karls-University, Tuebingen, Germany. METHODS Patients with high myopia having phacoemulsification with implantation of an AcrySof MA60MA IOL (power range +5.00 to -5.00 diopters [D]) were evalua...
متن کاملAxial length changes in highly myopic eyes and influence of myopic macular complications in Japanese adults
PURPOSE To investigate changes of the axial length in normal eyes and highly myopic eyes and influence of myopic macular complications in Japanese adults. STUDY DESIGN Retrospective longitudinal case series. METHODS The changes in the axial length of 316 eyes from 316 patients (mean age, 63.8 ± 9.0 years; range, 34-82; 240 females) examined using IOLMaster with a follow-up period of at leas...
متن کاملThe effect of testing distance on intraocular lens power calculation.
The calculation of the intraocular lens (IOL) power required for a specific patient typically uses a “lens constant” back-calculated from the refractive outcomes of earlier surgical results.1,2 An early recommendation was for clinicians to personalize their own lens constants to address systematic errors. However, the introduction of phacoemulsification equipment, continuous curvilinear capsulo...
متن کاملAccuracy of axial length measurements from immersion B-scan ultrasonography in highly myopic eyes.
AIM To evaluate the accuracy of axial length (AL) measurements obtained from immersion B-scan ultrasonography (immersion B-scan) for intraocular lens (IOL) power calculation in patients with high myopia and cataracts. METHODS Immersion B-scan, contact A-scan ultrasonography (contact A-scan), and the IOLMaster were used to preoperatively measure the AL in 102 eyes from 102 patients who underwe...
