PURPOSE To compare the accuracy of intraocular lens (IOL) power calculation methods for post-myopic excimer laser surgery patients without previous refractive surgery data using the Holladay IOL Consultant Program and the American Society of Cataract and Refractive Surgery (ASCRS) IOL Power Calculator. SETTING Wang Vision Cataract and LASIK Center, Nashville, Tennessee, USA. DESIGN Case ser...

PURPOSE To determine the accuracy of Pentacam Scheimpflug system Holladay equivalent keratometry (K) readings (EKRs) in calculating intraocular lens (IOL) power after corneal refractive surgery, including laser in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), and radial keratotomy (RK). SETTING Jules Stein Eye Institute, David Geffen School of Medicine at University of Calif...

The refractive result is a criterion for the quality of surgical correction cataract. aim this study was to analyze results obtained in calculating optical power intraocular lens (IOL), by applying formulas Holladay II and Barrett Universal II, treatment patients. conducted over period 2 years analyzed 235 eyes 160 patients (80 women 80 men) who underwent surgery at MMA Eye Clinic (Sofia) betwe...

purpose : to evaluate the accuracy of the two methods the clinical history method (chm), and the contact lens method (clm), in refractive corneal power determination and comparing the accuracy of srk ii, srk t and holladay ii (h ii) formulas for intraocular lens (iol) power calculation in patients who had laser in situ keratomileusis (lasik) surgery for myopia with or without astigmatism method...

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...

Aims: To study the refractive outcome of cataract surgery employing IOLMaster biometry data and to compare it with that of applanation ultrasonography in a prospective study of 100 eyes that underwent phacoemulsification with intraocular lens implantation. Methods: The Holladay formula using IOLMaster data was employed for the prediction of implanted intraocular lenses (IOLs). One month after c...

BACKGROUND In the 1920s and 1930s, disability glare was a topic of great interest in the Commission Internationale de l'Eclairage (CIE). The Second World War prevented agreement being reached on a standard to quantify disability glare but the Stiles-Holladay formula was widely accepted as such. In 1983, CIE started a new effort to develop a CIE standard making use of research data published in ...

PURPOSE Cataract development is common following retinal detachment surgery that necessitates silicone oil injection. Intraocular lens (IOL) power calculation in the presence of silicone oil is challenging for many reasons. The authors evaluated the accuracy of intraoperative biometry during cataract surgery in silicone-filled eyes. METHODS Twelve cases of cataract in eyes filled with silicon...
